Israel CAA PPL Theory Exam cheat sheet

ICAO Annex 2 classifies airspace into A-G; controlled airspace is A-E (and class F in some states), class G is uncontrolled; VFR is normally not permitted in class A.

VMC minima at and above 3,050 m (10,000 ft) AMSL: 8 km flight visibility, 1,500 m horizontal and 300 m (1,000 ft) vertical distance from cloud; below 3,050 m: 5 km visibility, 1,500 m horizontal, 300 m vertical.

Special VFR in a control zone requires ATC clearance, ground visibility of at least 1,500 m (Israel: per local AIP), remains clear of cloud and in sight of ground; it does not change the aircraft's VFR/IFR flight plan status.

Semi-circular rule (cruising levels, magnetic track): 000-179 use odd thousands (FL 10, 30, 50...), 180-359 use even thousands (FL 20, 40, 60...); IFR uses the same levels in most states.

Quadrantal rule applies in some airspace (Israel follows ICAO semi-circular rule for IFR/VFR cruising levels above the transition altitude).

Right-of-way: converging aircraft of the same category - the one on the right has right of way; head-on - both turn right; overtaking - the overtaken aircraft has right of way; landing aircraft have priority over taxiing aircraft.

An aircraft must not fly closer than 150 m (500 ft) to any person, vessel, vehicle or structure except with permission or during take-off/landing; over congested areas of cities, minimum 300 m (1,000 ft) above the highest obstacle within 600 m.

ATC clearance: read back all clearances involving runway, holding point, altitude, heading and SSR code; an ATC clearance does not relieve the pilot from responsibility for terrain separation and wake turbulence avoidance.

Wake turbulence categories: L (<=7,000 kg), M (7,000-136,000 kg), H (>136,000 kg); separation minima depend on leading/following category (e.g., H behind H: 4 NM).

Emergency: MAYDAY (distress, repeated 3x) vs PAN PAN (urgency, repeated 3x); set transponder 7700 (emergency), 7600 (radio failure), 7500 (unlawful interference).

Four-stroke cycle: intake, compression, power, exhaust; two crankshaft revolutions per cycle; valve overlap improves volumetric efficiency.

Detonation is uncontrolled explosive combustion causing high cylinder pressure and temperature; causes: low octane, high manifold pressure, high CHT, lean mixture at high power; remedy: reduce MAP, enrich mixture, reduce temperature.

Pre-ignition occurs when the charge ignites before spark; causes: hot spots (carbon deposits, spark plug electrode); can lead to detonation and engine damage.

Mixture: best power ratio approximately 12:1 (fuel:air), best economy approximately 16:1; EGT peaks at stoichiometric ratio (approximately 15:1); lean of peak reduces power and CHT.

Magneto: engine-driven, self-generating; two magnetos provide redundancy; a magneto check drop of more than 150 RPM or 50 RPM difference between magnetos is abnormal.

Carburettor icing: most likely at 0 to +15 °C with high humidity; use carb heat before reducing power; apply full carb heat if icing suspected; carb heat reduces power by approximately 5-10%.

Constant-speed propeller: governor controls RPM by varying blade angle; oil pressure to the governor increases pitch (coarser) to reduce RPM; loss of oil pressure drives propeller to fine pitch (high RPM).

Electrical: bus bar, alternator, battery, voltage regulator; alternator failure indicated by zero ammeter/voltage drop; battery alone provides limited endurance (typically 20-30 min in light aircraft).

Electrical system: master switch controls battery and alternator contactors; circuit breakers protect circuits; ammeter shows charge/discharge; a stuck starter contactor can be identified by continued ammeter discharge after engine start.

Hydraulic/brake system: check fluid level, no leaks; brake fade from overheating; parking brake should not be set with hot brakes.

Mass and balance: MTOW, MLW, MZFW, MRW limits; CG must lie between forward and aft limits; forward CG increases stability but increases stall speed and landing distance; aft CG reduces stability and can cause pitch-up.

Moment = mass × arm; CG = total moment / total mass; use datum (reference point) consistently; shifting mass formula: shift = (mass moved × distance moved) / total mass.

Density altitude = pressure altitude + 120 × (OAT - ISA temp at that level); ISA sea level 15 °C, lapse 1.98 °C/1,000 ft; high DA reduces power, thrust and lift, increases TAS and take-off/landing distances.

Take-off distance (TOD) and take-off run (TOR) increase with mass, altitude, temperature, headwind reduction, tailwind, uphill slope, dry/wet grass; wet grass factor approximately 1.15-1.30.

Landing distance increases with mass, altitude, temperature, tailwind, downhill slope, wet/contaminated runway; approach speed increase of 10% increases landing distance approximately 20%.

Climb gradient (%) = (altitude gain / horizontal distance) × 100; ROC (ft/min) = gradient × groundspeed (kt) × 101.3 / 60 (approximately gradient × GS × 1.69).

Endurance = usable fuel / fuel consumption; range = TAS × endurance; specific range = TAS / fuel flow; best range in still air at maximum L/D, best endurance at minimum power required.

Flight plan fuel: trip fuel + contingency (usually 5% of trip fuel) + alternate fuel + final reserve (30 min at holding speed, 45 min for IFR commercial) + taxi fuel.

ISA deviation: pressure altitude from altimeter set to 1013.25 hPa; true altitude = indicated altitude + 4 ft per 1,000 ft per 1 °C ISA deviation (approximately).

Load sheet: verify zero fuel mass, take-off mass, landing mass, CG position within envelope; last-minute changes (LMC) must be recorded and checked against limits.

Hypoxia types: hypoxic (altitude, reduced oxygen partial pressure), hypemic (anaemia, CO poisoning), stagnant (G-forces, poor circulation), histotoxic (alcohol, drugs).

Time of useful consciousness (TUC) at 25,000 ft approximately 3-5 min; at 35,000 ft approximately 30-60 s; at 40,000 ft approximately 15-20 s; supplemental oxygen required above 10,000 ft (Israel: per local regulation, typically 10,000 ft).

Hyperventilation causes hypocapnia (low CO2), leading to dizziness, tingling, and possible unconsciousness; treatment: slow breathing, talk aloud, reduce rate; distinguish from hypoxia by response to oxygen.

Spatial disorientation: somatogyral illusion (false sensation of rotation), somatogravic illusion (false pitch sensation during acceleration), Coriolis illusion (head movement during turn); trust instruments, not sensations.

Grey-out/black-out from positive G; red-out from negative G; G-LOC occurs around +5 to +6 G sustained without anti-G measures; straining manoeuvre (M1) increases tolerance.

Vision: foveal (cones, colour, detail) vs peripheral (rods, night vision, motion detection); night vision requires 30 min dark adaptation; avoid bright light and smoking before night flight; empty-field myopia and autokinesis affect night approaches.

Hearing: noise-induced hearing loss from prolonged exposure above 85 dB; use headsets; hearing protection and ANR reduce risk; vestibular system can mislead in IMC.

Stress: performance follows the Yerkes-Dodson curve; moderate arousal optimises performance; chronic stress reduces attention and decision quality; use checklists and prioritise aviate-navigate-communicate.

Fatigue: circadian low at 02:00-06:00 and 14:00-16:00; sleep debt impairs reaction time and judgement; controlled rest and proper pre-flight rest are primary mitigations.

Alcohol: elimination approximately 0.015% BAC per hour; effects persist after BAC returns to zero; Israel CAA rule: no alcohol within 8 hours before flight and BAC below 0.02% (verify current regulation).

ISA: sea level 15 °C, 1013.25 hPa, lapse rate 1.98 °C/1,000 ft up to 11 km (tropopause), then isothermal to 20 km.

QNH = pressure reduced to sea level (altimeter reads elevation when set); QFE = pressure at aerodrome elevation (altimeter reads zero on ground); QNE = 1013.25 hPa (standard).

Altimeter: flying from high to low pressure without resetting causes the altimeter to over-read (aircraft lower than indicated); from high to low temperature also over-reads; use 'high to low, look out below'.

Cloud base estimate: cloud base (ft) = (temperature - dew point) × 400 (for spread in °C, at surface); convergence and lifting increase cloud; subsidence decreases it.

Stability: stable air - stratiform cloud, steady precipitation, smooth air, poor visibility; unstable air - cumuliform cloud, showers, turbulence, good visibility outside precipitation.

Fronts: cold front - rapid passage, cumulonimbus, gusty winds, veering wind, rapid pressure rise; warm front - gradual, stratiform, steady rain, backing wind, slow pressure fall.

Thunderstorm life cycle: cumulus (updrafts), mature (updrafts and downdrafts, hail, lightning, gust front), dissipating (downdrafts); avoid by at least 20 NM, do not fly under the anvil.

Icing: clear ice from large supercooled droplets (0 to -10 °C), rime ice from small droplets (-10 to -20 °C); most severe in cumuliform cloud; use anti-ice/de-ice and exit conditions.

Wind: surface friction reduces wind speed and backs direction over land; veering with height in the northern hemisphere (Ekman spiral); mountain waves produce lenticular clouds and severe turbulence on the lee side.

Israel climate: Mediterranean coastal climate, hot dry summers (Sharav/sirocco with low humidity and haze), winter rains from October to April, occasional dust storms (khamsin), sea breeze along the coast in afternoon.

Great circle = shortest path on a sphere; rhumb line = constant track crossing all meridians at the same angle; Mercator projection shows rhumb lines as straight lines, great circles as curved.

1 minute of latitude = 1 NM (approximately 1,852 m); 1 minute of longitude = 1 NM × cos(latitude); 1 degree = 60 NM.

Track vs heading: heading = track ± wind correction angle; drift = difference between heading and track; wind correction angle = arcsin((wind speed / TAS) × sin(wind angle)).

Triangle of velocities: GS and track derived from TAS, heading, wind speed and direction; use the wind side of the flight computer or vector addition; GS = TAS only in still air.

VOR: 108.0-117.95 MHz, line-of-sight, provides radial (magnetic bearing from station); CDI centred with TO/FROM indicates on-radial; reverse sensing if OBS set incorrectly.

NDB/ADF: 190-535 kHz (NDB usually 200-415 kHz), bearing relative to aircraft; ADF needle points to station; relative bearing + heading = magnetic bearing to station.

ILS: localiser 108.10-111.95 MHz (odd tenths), glideslope 329.15-335.0 MHz; localiser provides lateral guidance, glideslope typically 3° (approximately 300 ft/NM); marker beacons at outer, middle, inner.

GPS: requires at least 4 satellites for 3D fix, 5 for RAIM; RAIM predicts integrity; if RAIM unavailable, alternate means of navigation required.

Transponder: Mode A code (4 octal digits), Mode C includes pressure altitude; squawk 7000 (VFR Europe), 7500/7600/7700 emergency codes; Israel uses 7000 for VFR (verify AIP).

Time and longitude: 15° = 1 hour; local mean time = UTC ± longitude/15; sunrise/sunset tables use latitude and date; Israel is UTC+2 (winter) / UTC+3 (summer, IDT).

Pre-flight: check NOTAMs, weather, mass and balance, fuel, documents (ARO, certificate of registration, airworthiness, licences, insurance), and aircraft technical log.

Take-off briefing: engine failure before/after Vr, rejected take-off decision, crosswind limit, abort point; for light twins, Vmc demonstration and single-engine procedure.

Engine failure after take-off (single-engine): pitch for best glide speed (Vy), select landing site, attempt restart only if altitude permits, MAYDAY call, forced landing checklist; do not turn back below 500 ft AGL.

Fire: engine fire - fuel selector OFF, mixture idle cut-off, master OFF, extinguisher, forced landing; cabin/electrical fire - master OFF, extinguisher, ventilate, land as soon as possible.

Emergency descent: oxygen masks on, squawk 7700, MAYDAY, descend at Vmo/Mmo or maximum practicable, turn away from terrain and traffic, advise ATC.

Radio failure (IFR): squawk 7600, maintain last assigned level for 7 min, then follow flight plan; VFR: remain VMC, land at nearest suitable aerodrome, advise ATC on landing.

Wake turbulence: avoid by flying above the preceding aircraft's flight path, land beyond its touchdown point, take off before its rotation point; stay upwind.

Runway incursion prevention: read back hold-short instructions, use standard phraseology, maintain situational awareness, sterilise cockpit during taxi.

Emergency equipment: fire extinguisher, first aid kit, ELT (121.5/406 MHz), life jackets (over water), survival kit; check serviceability and expiry dates.

Post-flight: report defects in technical log, complete journey log, report occurrences (mandatory occurrence reporting per Israel CAA).

Lift L = ½ ρ V² S CL; induced drag Di = L² / (½ ρ V² π b² e); parasite drag Dp = ½ ρ V² S CD0; total drag minimum at speed where induced = parasite drag (best L/D speed).

Angle of attack is the angle between chord line and relative airflow; stall occurs at critical AoA (typically 15-18°) regardless of speed, mass, or attitude; stall speed increases with mass (Vs ∝ √mass) and load factor (Vs ∝ √n).

Load factor n = L/W; in a level turn n = 1/cos(bank); at 60° bank n = 2, stall speed increases by √2 (approximately 41%).

Stability: positive static stability (tendency to return), positive dynamic stability (oscillation damped); longitudinal stability requires CG forward of the neutral point; dihedral provides lateral stability.

Control: elevator controls pitch, ailerons roll, rudder yaw; adverse yaw from aileron drag countered by rudder; aileron reversal at high speed due to wing twist; Vne is the never-exceed speed.

Flaps: increase CLmax and drag; lowering flaps decreases stall speed and increases lift at a given speed but increases drag; go-around: reduce flaps in stages to avoid sink.

Mach effects: critical Mach number is where local airflow reaches Mach 1; shock waves cause drag rise, buffet, and Mach tuck; swept wings increase critical Mach.

Spin: aggravated stall with yaw; recovery: power idle, ailerons neutral, full opposite rudder, forward elevator, then recover from dive; spin differs from spiral dive (ASI increasing, high G).

Ground effect: within one wingspan of the ground, induced drag reduces and lift increases; aircraft may float on landing and feel 'sinking' on climb-out.

Propeller: thrust = mass flow × velocity change; propeller efficiency highest at cruise; constant-speed propeller maintains RPM; windmilling propeller produces high drag.

Standard call: station called, station calling, position, altitude, intention; e.g., 'Tel Aviv Approach, 4X-ABC, Cessna 172, 5 NM south, 2,500 ft, request landing information'.

Read-back requirements: ATC clearances, runway, hold-short, altitude, heading, SSR code, frequency; read back exactly as given.

Phonetic alphabet: Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu.

Numbers: 0 zero, 1 one, 2 two, 3 tree, 4 fower, 5 fife, 6 six, 7 seven, 8 eight, 9 niner; altitudes in hundreds of feet ('two thousand five hundred' or 'two five hundred').

Emergency: MAYDAY MAYDAY MAYDAY (distress) - callsign, nature, position, altitude, intention; PAN PAN PAN PAN PAN PAN (urgency); use 121.5 MHz for emergency.

VFR position report: callsign, position, altitude, next position and ETA; use 'over', 'out', 'roger', 'wilco', 'affirm', 'negative', 'standby', 'say again'.

ATIS: record the information code (e.g., 'Information Alpha'), QNH, runway in use, wind, visibility, cloud; advise ATC on initial call that you have the ATIS.

Transponder phraseology: 'squawk 7000', 'squawk ident' (press ident button), 'confirm squawk'; ATC may instruct 'stop squawk', 'squawk standby'.

Frequency change: 'contact Tower 118.4', 'request frequency change'; maintain listening watch on assigned frequency; 121.5 MHz emergency frequency monitored when practicable.

Israel RT: English is standard for international operations; Hebrew used on some domestic frequencies; use standard ICAO phraseology; Israel CAA AIP SUP for local procedures.

Israel CAA (Civil Aviation Authority of Israel) regulates licensing, airworthiness, and operations under the Aviation Law; PPL issued per ICAO Annex 1 standards; check current CAAI publications for validity periods and medical requirements.

Airspace: Israel has FIR Tel Aviv (LLLL); controlled airspace classes A-E; Ben Gurion (LLBG) is class C/D; military airspace (e.g., Nevatim, Hatzerim) requires coordination; check AIP Israel for current boundaries.

VFR flight in Israel: flight plan required for cross-country and for entry into controlled airspace; PPR may be required at some aerodromes; radio mandatory in controlled airspace.

Local procedures: Ben Gurion special VFR and noise abatement procedures; coastal and low-level routes; parachute and glider activity areas; firing zones and danger areas (e.g., in the Negev) must be avoided.

Weather minima: Israel VFR minima in controlled airspace per AIP; coastal fog in winter mornings; Sharav conditions in spring/summer with haze and turbulence.

Security: Ben Gurion and other airports have security zones; pilots must follow instructions; EL AL and other operators have specific procedures; do not enter restricted areas (e.g., Dimona nuclear site).

Licensing: PPL(A) requires 45 h total time (per ICAO/EASA standard; verify current CAAI requirement), including dual and solo; class 2 medical; radio telephony licence; biennial flight review (check current CAAI validity).

Aircraft registration: 4X- prefix; certificate of airworthiness; maintenance per CAAI-approved programme; annual inspection; ELT and transponder requirements per CAAI.

Flight plan filing: file with ARO at least 30 min before departure (verify current); close flight plan after landing; SAR alerting if not closed.

Accident/incident reporting: report to CAAI AIB (Accident Investigation Board) and to ATC; mandatory occurrence reporting scheme; preserve evidence and records.

ICAO Annex 2 classifies airspace into A-G; controlled airspace is A-E (and class F in some states), class G is uncontrolled; VFR is normally not permitted in class A.

VMC minima at and above 3,050 m (10,000 ft) AMSL: 8 km flight visibility, 1,500 m horizontal and 300 m (1,000 ft) vertical distance from cloud; below 3,050 m: 5 km visibility, 1,500 m horizontal, 300 m vertical.

Special VFR in a control zone requires ATC clearance, ground visibility of at least 1,500 m (Israel: per local AIP), remains clear of cloud and in sight of ground; it does not change the aircraft's VFR/IFR flight plan status.

Semi-circular rule (cruising levels, magnetic track): 000-179 use odd thousands (FL 10, 30, 50...), 180-359 use even thousands (FL 20, 40, 60...); IFR uses the same levels in most states.

Quadrantal rule applies in some airspace (Israel follows ICAO semi-circular rule for IFR/VFR cruising levels above the transition altitude).

Right-of-way: converging aircraft of the same category - the one on the right has right of way; head-on - both turn right; overtaking - the overtaken aircraft has right of way; landing aircraft have priority over taxiing aircraft.

An aircraft must not fly closer than 150 m (500 ft) to any person, vessel, vehicle or structure except with permission or during take-off/landing; over congested areas of cities, minimum 300 m (1,000 ft) above the highest obstacle within 600 m.

ATC clearance: read back all clearances involving runway, holding point, altitude, heading and SSR code; an ATC clearance does not relieve the pilot from responsibility for terrain separation and wake turbulence avoidance.

Wake turbulence categories: L (<=7,000 kg), M (7,000-136,000 kg), H (>136,000 kg); separation minima depend on leading/following category (e.g., H behind H: 4 NM).

Emergency: MAYDAY (distress, repeated 3x) vs PAN PAN (urgency, repeated 3x); set transponder 7700 (emergency), 7600 (radio failure), 7500 (unlawful interference).

Four-stroke cycle: intake, compression, power, exhaust; two crankshaft revolutions per cycle; valve overlap improves volumetric efficiency.

Detonation is uncontrolled explosive combustion causing high cylinder pressure and temperature; causes: low octane, high manifold pressure, high CHT, lean mixture at high power; remedy: reduce MAP, enrich mixture, reduce temperature.

Pre-ignition occurs when the charge ignites before spark; causes: hot spots (carbon deposits, spark plug electrode); can lead to detonation and engine damage.

Mixture: best power ratio approximately 12:1 (fuel:air), best economy approximately 16:1; EGT peaks at stoichiometric ratio (approximately 15:1); lean of peak reduces power and CHT.

Magneto: engine-driven, self-generating; two magnetos provide redundancy; a magneto check drop of more than 150 RPM or 50 RPM difference between magnetos is abnormal.

Carburettor icing: most likely at 0 to +15 °C with high humidity; use carb heat before reducing power; apply full carb heat if icing suspected; carb heat reduces power by approximately 5-10%.

Constant-speed propeller: governor controls RPM by varying blade angle; oil pressure to the governor increases pitch (coarser) to reduce RPM; loss of oil pressure drives propeller to fine pitch (high RPM).

Electrical: bus bar, alternator, battery, voltage regulator; alternator failure indicated by zero ammeter/voltage drop; battery alone provides limited endurance (typically 20-30 min in light aircraft).

Electrical system: master switch controls battery and alternator contactors; circuit breakers protect circuits; ammeter shows charge/discharge; a stuck starter contactor can be identified by continued ammeter discharge after engine start.

Hydraulic/brake system: check fluid level, no leaks; brake fade from overheating; parking brake should not be set with hot brakes.

Mass and balance: MTOW, MLW, MZFW, MRW limits; CG must lie between forward and aft limits; forward CG increases stability but increases stall speed and landing distance; aft CG reduces stability and can cause pitch-up.

Moment = mass × arm; CG = total moment / total mass; use datum (reference point) consistently; shifting mass formula: shift = (mass moved × distance moved) / total mass.

Density altitude = pressure altitude + 120 × (OAT - ISA temp at that level); ISA sea level 15 °C, lapse 1.98 °C/1,000 ft; high DA reduces power, thrust and lift, increases TAS and take-off/landing distances.

Take-off distance (TOD) and take-off run (TOR) increase with mass, altitude, temperature, headwind reduction, tailwind, uphill slope, dry/wet grass; wet grass factor approximately 1.15-1.30.

Landing distance increases with mass, altitude, temperature, tailwind, downhill slope, wet/contaminated runway; approach speed increase of 10% increases landing distance approximately 20%.

Climb gradient (%) = (altitude gain / horizontal distance) × 100; ROC (ft/min) = gradient × groundspeed (kt) × 101.3 / 60 (approximately gradient × GS × 1.69).

Endurance = usable fuel / fuel consumption; range = TAS × endurance; specific range = TAS / fuel flow; best range in still air at maximum L/D, best endurance at minimum power required.

Flight plan fuel: trip fuel + contingency (usually 5% of trip fuel) + alternate fuel + final reserve (30 min at holding speed, 45 min for IFR commercial) + taxi fuel.

ISA deviation: pressure altitude from altimeter set to 1013.25 hPa; true altitude = indicated altitude + 4 ft per 1,000 ft per 1 °C ISA deviation (approximately).

Load sheet: verify zero fuel mass, take-off mass, landing mass, CG position within envelope; last-minute changes (LMC) must be recorded and checked against limits.

Hypoxia types: hypoxic (altitude, reduced oxygen partial pressure), hypemic (anaemia, CO poisoning), stagnant (G-forces, poor circulation), histotoxic (alcohol, drugs).

Time of useful consciousness (TUC) at 25,000 ft approximately 3-5 min; at 35,000 ft approximately 30-60 s; at 40,000 ft approximately 15-20 s; supplemental oxygen required above 10,000 ft (Israel: per local regulation, typically 10,000 ft).

Hyperventilation causes hypocapnia (low CO2), leading to dizziness, tingling, and possible unconsciousness; treatment: slow breathing, talk aloud, reduce rate; distinguish from hypoxia by response to oxygen.

Spatial disorientation: somatogyral illusion (false sensation of rotation), somatogravic illusion (false pitch sensation during acceleration), Coriolis illusion (head movement during turn); trust instruments, not sensations.

Grey-out/black-out from positive G; red-out from negative G; G-LOC occurs around +5 to +6 G sustained without anti-G measures; straining manoeuvre (M1) increases tolerance.

Vision: foveal (cones, colour, detail) vs peripheral (rods, night vision, motion detection); night vision requires 30 min dark adaptation; avoid bright light and smoking before night flight; empty-field myopia and autokinesis affect night approaches.

Fatigue: circadian low at 02:00-06:00 and 14:00-16:00; sleep debt impairs reaction time and judgement; controlled rest and proper pre-flight rest are primary mitigations.

Alcohol: elimination approximately 0.015% BAC per hour; effects persist after BAC returns to zero; Israel CAA rule: no alcohol within 8 hours before flight and BAC below 0.02% (verify current regulation).

ISA: sea level 15 °C, 1013.25 hPa, lapse rate 1.98 °C/1,000 ft up to 11 km (tropopause), then isothermal to 20 km.

QNH = pressure reduced to sea level (altimeter reads elevation when set); QFE = pressure at aerodrome elevation (altimeter reads zero on ground); QNE = 1013.25 hPa (standard).

Altimeter: flying from high to low pressure without resetting causes the altimeter to over-read (aircraft lower than indicated); from high to low temperature also over-reads; use 'high to low, look out below'.

Cloud base estimate: cloud base (ft) = (temperature - dew point) × 400 (for spread in °C, at surface); convergence and lifting increase cloud; subsidence decreases it.

Stability: stable air - stratiform cloud, steady precipitation, smooth air, poor visibility; unstable air - cumuliform cloud, showers, turbulence, good visibility outside precipitation.

Fronts: cold front - rapid passage, cumulonimbus, gusty winds, veering wind, rapid pressure rise; warm front - gradual, stratiform, steady rain, backing wind, slow pressure fall.

Thunderstorm life cycle: cumulus (updrafts), mature (updrafts and downdrafts, hail, lightning, gust front), dissipating (downdrafts); avoid by at least 20 NM, do not fly under the anvil.

Icing: clear ice from large supercooled droplets (0 to -10 °C), rime ice from small droplets (-10 to -20 °C); most severe in cumuliform cloud; use anti-ice/de-ice and exit conditions.

Wind: surface friction reduces wind speed and backs direction over land; veering with height in the northern hemisphere (Ekman spiral); mountain waves produce lenticular clouds and severe turbulence on the lee side.

Israel climate: Mediterranean coastal climate, hot dry summers (Sharav/sirocco with low humidity and haze), winter rains from October to April, occasional dust storms (khamsin), sea breeze along the coast in afternoon.

Great circle = shortest path on a sphere; rhumb line = constant track crossing all meridians at the same angle; Mercator projection shows rhumb lines as straight lines, great circles as curved.

1 minute of latitude = 1 NM (approximately 1,852 m); 1 minute of longitude = 1 NM × cos(latitude); 1 degree = 60 NM.

Track vs heading: heading = track ± wind correction angle; drift = difference between heading and track; wind correction angle = arcsin((wind speed / TAS) × sin(wind angle)).

Triangle of velocities: GS and track derived from TAS, heading, wind speed and direction; use the wind side of the flight computer or vector addition; GS = TAS only in still air.

VOR: 108.0-117.95 MHz, line-of-sight, provides radial (magnetic bearing from station); CDI centred with TO/FROM indicates on-radial; reverse sensing if OBS set incorrectly.

NDB/ADF: 190-535 kHz (NDB usually 200-415 kHz), bearing relative to aircraft; ADF needle points to station; relative bearing + heading = magnetic bearing to station.

ILS: localiser 108.10-111.95 MHz (odd tenths), glideslope 329.15-335.0 MHz; localiser provides lateral guidance, glideslope typically 3° (approximately 300 ft/NM); marker beacons at outer, middle, inner.

GPS: requires at least 4 satellites for 3D fix, 5 for RAIM; RAIM predicts integrity; if RAIM unavailable, alternate means of navigation required.

Transponder: Mode A code (4 octal digits), Mode C includes pressure altitude; squawk 7000 (VFR Europe), 7500/7600/7700 emergency codes; Israel uses 7000 for VFR (verify AIP).

Time and longitude: 15° = 1 hour; local mean time = UTC ± longitude/15; sunrise/sunset tables use latitude and date; Israel is UTC+2 (winter) / UTC+3 (summer, IDT).

Pre-flight: check NOTAMs, weather, mass and balance, fuel, documents (ARO, certificate of registration, airworthiness, licences, insurance), and aircraft technical log.

Take-off briefing: engine failure before/after Vr, rejected take-off decision, crosswind limit, abort point; for light twins, Vmc demonstration and single-engine procedure.

Engine failure after take-off (single-engine): pitch for best glide speed (Vy), select landing site, attempt restart only if altitude permits, MAYDAY call, forced landing checklist; do not turn back below 500 ft AGL.

Fire: engine fire - fuel selector OFF, mixture idle cut-off, master OFF, extinguisher, forced landing; cabin/electrical fire - master OFF, extinguisher, ventilate, land as soon as possible.

Emergency descent: oxygen masks on, squawk 7700, MAYDAY, descend at Vmo/Mmo or maximum practicable, turn away from terrain and traffic, advise ATC.

Radio failure (IFR): squawk 7600, maintain last assigned level for 7 min, then follow flight plan; VFR: remain VMC, land at nearest suitable aerodrome, advise ATC on landing.

Wake turbulence: avoid by flying above the preceding aircraft's flight path, land beyond its touchdown point, take off before its rotation point; stay upwind.

Runway incursion prevention: read back hold-short instructions, use standard phraseology, maintain situational awareness, sterilise cockpit during taxi.

Emergency equipment: fire extinguisher, first aid kit, ELT (121.5/406 MHz), life jackets (over water), survival kit; check serviceability and expiry dates.

Post-flight: report defects in technical log, complete journey log, report occurrences (mandatory occurrence reporting per Israel CAA).

Lift L = ½ ρ V² S CL; induced drag Di = L² / (½ ρ V² π b² e); parasite drag Dp = ½ ρ V² S CD0; total drag minimum at speed where induced = parasite drag (best L/D speed).

Angle of attack is the angle between chord line and relative airflow; stall occurs at critical AoA (typically 15-18°) regardless of speed, mass, or attitude; stall speed increases with mass (Vs ∝ √mass) and load factor (Vs ∝ √n).

Load factor n = L/W; in a level turn n = 1/cos(bank); at 60° bank n = 2, stall speed increases by √2 (approximately 41%).

Stability: positive static stability (tendency to return), positive dynamic stability (oscillation damped); longitudinal stability requires CG forward of the neutral point; dihedral provides lateral stability.

Control: elevator controls pitch, ailerons roll, rudder yaw; adverse yaw from aileron drag countered by rudder; aileron reversal at high speed due to wing twist; Vne is the never-exceed speed.

Flaps: increase CLmax and drag; lowering flaps decreases stall speed and increases lift at a given speed but increases drag; go-around: reduce flaps in stages to avoid sink.

Mach effects: critical Mach number is where local airflow reaches Mach 1; shock waves cause drag rise, buffet, and Mach tuck; swept wings increase critical Mach.

Spin: aggravated stall with yaw; recovery: power idle, ailerons neutral, full opposite rudder, forward elevator, then recover from dive; spin differs from spiral dive (ASI increasing, high G).

Ground effect: within one wingspan of the ground, induced drag reduces and lift increases; aircraft may float on landing and feel 'sinking' on climb-out.

Propeller: thrust = mass flow × velocity change; propeller efficiency highest at cruise; constant-speed propeller maintains RPM; windmilling propeller produces high drag.

Standard call: station called, station calling, position, altitude, intention; e.g., 'Tel Aviv Approach, 4X-ABC, Cessna 172, 5 NM south, 2,500 ft, request landing information'.

Read-back requirements: ATC clearances, runway, hold-short, altitude, heading, SSR code, frequency; read back exactly as given.

Phonetic alphabet: Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu.

Numbers: 0 zero, 1 one, 2 two, 3 tree, 4 fower, 5 fife, 6 six, 7 seven, 8 eight, 9 niner; altitudes in hundreds of feet ('two thousand five hundred' or 'two five hundred').

Emergency: MAYDAY MAYDAY MAYDAY (distress) - callsign, nature, position, altitude, intention; PAN PAN PAN PAN PAN PAN (urgency); use 121.5 MHz for emergency.

VFR position report: callsign, position, altitude, next position and ETA; use 'over', 'out', 'roger', 'wilco', 'affirm', 'negative', 'standby', 'say again'.

ATIS: record the information code (e.g., 'Information Alpha'), QNH, runway in use, wind, visibility, cloud; advise ATC on initial call that you have the ATIS.

Transponder phraseology: 'squawk 7000', 'squawk ident' (press ident button), 'confirm squawk'; ATC may instruct 'stop squawk', 'squawk standby'.

Frequency change: 'contact Tower 118.4', 'request frequency change'; maintain listening watch on assigned frequency; 121.5 MHz emergency frequency monitored when practicable.

Israel RT: English is standard for international operations; Hebrew used on some domestic frequencies; use standard ICAO phraseology; Israel CAA AIP SUP for local procedures.

Israel CAA (Civil Aviation Authority of Israel) regulates licensing, airworthiness, and operations under the Aviation Law; PPL issued per ICAO Annex 1 standards; check current CAAI publications for validity periods and medical requirements.

Airspace: Israel has FIR Tel Aviv (LLLL); controlled airspace classes A-E; Ben Gurion (LLBG) is class C/D; military airspace (e.g., Nevatim, Hatzerim) requires coordination; check AIP Israel for current boundaries.

VFR flight in Israel: flight plan required for cross-country and for entry into controlled airspace; PPR may be required at some aerodromes; radio mandatory in controlled airspace.

Local procedures: Ben Gurion special VFR and noise abatement procedures; coastal and low-level routes; parachute and glider activity areas; firing zones and danger areas (e.g., in the Negev) must be avoided.

Weather minima: Israel VFR minima in controlled airspace per AIP; coastal fog in winter mornings; Sharav conditions in spring/summer with haze and turbulence.

Security: Ben Gurion and other airports have security zones; pilots must follow instructions; EL AL and other operators have specific procedures; do not enter restricted areas (e.g., Dimona nuclear site).

Licensing: PPL(A) requires 45 h total time (per ICAO/EASA standard; verify current CAAI requirement), including dual and solo; class 2 medical; radio telephony licence; biennial flight review (check current CAAI validity).

Aircraft registration: 4X- prefix; certificate of airworthiness; maintenance per CAAI-approved programme; annual inspection; ELT and transponder requirements per CAAI.

Flight plan filing: file with ARO at least 30 min before departure (verify current); close flight plan after landing; SAR alerting if not closed.

Accident/incident reporting: report to CAAI AIB (Accident Investigation Board) and to ATC; mandatory occurrence reporting scheme; preserve evidence and records.
