PPL Aircraft General Knowledge study plan

PPL Aircraft General Knowledge · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Airframe, systems and powerplant

  • Sketch the airframe primary structure (fuselage, wing, empennage, landing gear) and label load paths and stress members from memory

  • Explain the four-stroke cycle and list the function of each major engine component (cylinder, piston, crankshaft, camshaft, valves)

  • Describe the carburettor and fuel metering system, including mixture control and the cause of carburettor icing

  • Distinguish the electrical, vacuum/pneumatic, hydraulic, and pitot-static system layouts on a light aircraft and state what each drives

Your checkpoint

One hand-drawn aircraft systems map with all major systems labelled and a one-page written summary of the piston engine cycle

Week 2

Airframe, systems and powerplant

  • Explain lubrication and cooling systems, including oil flow path, oil pressure/temperature limits, and cowl flap use

  • Describe the ignition system from magneto to spark plug and explain why dual ignition is fitted

  • Explain constant-speed propeller operation, pitch control, and the effect of RPM/MP settings on power

  • List the causes and symptoms of detonation and pre-ignition and the corrective actions

  • Interpret typical engine and system limitations from a POH-style limitations section

Your checkpoint

A 20-item self-quiz on powerplant and systems with written answers, scored and any item below full marks re-explained in your own words

Week 3

Mass and balance

  • Define mass, weight, arm, moment, and centre of gravity and compute a CG from a loading table

  • Convert between mass and weight using standard gravity and state the units used in load sheets

  • Calculate the effect of adding, removing, and shifting load on the CG position

  • Explain maximum take-off mass, maximum zero-fuel mass, and maximum landing mass and why each is limiting

  • Describe how CG position ahead of or behind the aft limit affects stability, stall recovery, and performance

Your checkpoint

Three fully worked loading problems (nose-loaded, aft-loaded, and within limits) with CG plotted on a moment envelope, all arithmetic shown

Week 4

Mass and balance & Performance

  • Compute take-off and landing distances from tabulated data, applying wind, slope, temperature, and pressure-altitude corrections

  • State the definition and use of the take-off, accelerate-stop, and landing distance concepts in light aircraft performance

  • Explain how density altitude is derived and its effect on engine power, propeller thrust, and lift

  • Describe climb performance: rate of climb, climb gradient, service ceiling, and the effect of mass and configuration

  • Interpret a typical performance chart and identify the assumptions printed on it

Your checkpoint

A performance worksheet solving four scenarios (hot/high, short field, tailwind landing, heavy mass) with corrected distances and a short note on which correction dominated each case

Week 5

Performance

  • Compute stall speeds at different masses using the square-root relationship and explain the load-factor effect on stall speed

  • Explain the forces in a turn, load factor in level and banked turns, and the resulting increase in stall speed

  • Describe the effect of flaps, gear, and contamination (ice, frost) on take-off, climb, and landing performance

  • Explain the factors affecting glide performance and the use of a glide ratio in a forced landing

  • Identify the factors that increase landing distance and state the recommended corrections

Your checkpoint

A one-page performance summary card (stall speed vs mass, load factor vs bank, and correction factors) that you can reproduce from memory in under five minutes

Week 6

Flight planning and monitoring

  • Plan a cross-country flight: select route, altitude, and alternates, and compute leg times and fuel from wind triangle data

  • Compute headwind/tailwind components and drift from wind speed and direction relative to track

  • Apply fuel reserves and calculate endurance and range from usable fuel and consumption

  • Interpret NOTAM-style and weather information relevant to a planned flight and state go/no-go criteria

  • Describe in-flight monitoring: fuel log, position reporting, and revising the plan when actual conditions differ

Your checkpoint

A complete written flight plan for a 250 nm cross-country with wind-corrected legs, fuel log, reserves, and a go/no-go decision with reasons

Week 7

Aircraft instruments & Electrics and electronics

  • Explain the pitot-static system and the errors affecting the altimeter, airspeed indicator, and vertical speed indicator

  • Describe the operation of the magnetic compass, turning and bank indicator, and heading indicator, and state their limitations

  • Explain gyroscopic principles (rigidity, precession) as applied to attitude and heading instruments

  • Describe a basic aircraft electrical system: battery, alternator/generator, bus, fuses/circuit breakers, and the meaning of a failed alternator

  • Interpret instrument readings in a given scenario and identify the most likely instrument or system fault

Your checkpoint

A two-column fault table: 15 abnormal indications mapped to the most probable instrument, electrical, or pitot-static cause, with a one-line justification each

Week 8

Airframe, systems and powerplant & Mass and balance & Performance & Flight planning and monitoring & Aircraft instruments & Electrics and electronics

  • Complete a timed mixed-domain mock test and record the score per domain

  • Re-study every domain where the mock score was below 75 percent, reworking the underlying calculation or system explanation

  • Reproduce the mass and balance and performance calculations under time pressure without notes

  • Recite the key definitions (CG, density altitude, load factor, service ceiling) in precise wording

  • Review flagged weak items and confirm each is now answered correctly with reasoning

Your checkpoint

A timed 60-question mock test scored by domain, plus a written remediation list with every missed item reworked and re-answered correctly

Milestones

Week 2: Score at least 80 percent on the 20-item powerplant and systems self-quiz, with no unanswered item on the engine cycle, lubrication, ignition, or propeller

Week 4: Solve a fresh mass and balance problem and a fresh take-off distance problem, unaided, with the correct CG inside limits and the correct wind/slope/temperature corrections applied

Week 6: Produce a complete cross-country flight plan with wind-corrected leg times, fuel log, and reserves, and defend the go/no-go decision in writing

Week 7: Score at least 80 percent on a 30-question instruments and electrics set, and correctly map at least 12 of 15 abnormal indications to their cause

Week 8: Score at least 85 percent overall on the timed 60-question mock with no single domain below 75 percent, and show reworked answers for every missed item
