8 weeks · About 6 hours per week
Advanced Aerodynamics
Derive and write out from memory the relationships between lift coefficient, angle of attack, and indicated airspeed for a fixed mass and load factor, explaining why stall speed varies with the square root of load factor
Sketch and label lift, drag, thrust and weight in a steady climb, glide and level turn, and calculate the load factor in a level 45-degree banked turn
Define critical angle of attack and explain, in writing, why stall is an angle-of-attack phenomenon rather than a speed phenomenon, including the effect of weight, load factor, CG position and ice contamination
Produce a one-page summary table of induced, parasite and total drag versus airspeed, marking minimum drag speed and minimum power speed and stating which is used for maximum endurance and maximum range
Your checkpoint
A closed-book written sheet of 15 self-set calculation and explanation questions on lift, drag, load factor and stall, scored and corrected, achieving at least 12 correct
Advanced Aerodynamics
Explain the causes of and recovery from shock stall and Mach tuck, including critical Mach number, local acceleration over the wing and the function of sweepback
Describe how a swept wing trades low-speed lift for high-speed delay of drag rise, and state the effects on stall characteristics and pitch-up tendencies
Calculate true airspeed from indicated airspeed and density altitude, and explain position error, compressibility error and instrument error in the high-speed regime
Compare stability in pitch, roll and yaw, explaining the roles of static margin, dihedral, fin area and CG position, and describe spiral divergence and Dutch roll and their standard recovery actions
Your checkpoint
A written comparison of straight and swept wing high-speed characteristics plus three worked TAS/compressibility problems, all answers checked against a reference text
Aircraft Performance
Define the four take-off and landing distance segments (ground roll, transition, climb, and for landing the approach and flare) and state which factors affect each
Calculate density altitude from pressure altitude and temperature, and explain its effect on take-off run, climb gradient and landing roll
Explain the effect of wind, slope, runway surface, flap setting, mass and anti-skid or reverse thrust on take-off and landing distances
Interpret a take-off distance required versus mass and density altitude relationship, and state the meaning of V1, VR, V2, VMCA, VMCG and VMBE
Your checkpoint
A set of eight worked performance problems (density altitude, take-off and landing distance corrections, wind and slope adjustments) with a formula sheet showing each step
Aircraft Performance
Calculate climb gradient and rate of climb from excess thrust or excess power, and convert between gradient and rate of climb at a given groundspeed
Explain the effect of mass, altitude, temperature and flap setting on climb performance, including the service ceiling and absolute ceiling
Explain the construction and use of the take-off flight path and obstacle clearance requirements, including net versus gross gradient and the 35 ft screen height
Distinguish maximum range from maximum endurance speeds and explain the effect of wind, altitude, mass and configuration on each
Your checkpoint
A timed 60-minute mock section of 25 performance questions (calculation and explanation), scored, with every error reworked and annotated
Aircraft Systems
Describe the layout and function of a typical hydraulic system, including reservoirs, pumps, accumulators, filters, relief valves and selector valves, and explain how system pressure is maintained
Explain the function of the electrical system, including busbar distribution, generators and alternators, battery, and the consequences of a generator failure on load shedding
Describe the pitot-static system, its sources of error (blocked pitot, blocked static, water in lines) and the resulting instrument indications
Explain the operation of the air data and attitude reference systems, including redundancy and failure indications
Your checkpoint
A hand-drawn schematic of the hydraulic and electrical systems with a written fault-effect table covering at least six failure cases
Aircraft Systems
Describe the fuel system from tanks through pumps, filters, valves and engine feed, and explain fuel imbalance, transfer and jettison procedures
Explain the operation of the ice and rain protection systems, including thermal, chemical and pneumatic de-icing, and the effect of airframe icing on performance and stall speed
Describe the pressurisation system, including outflow valve control, cabin altitude and differential pressure limits, and the response to a rapid decompression
Explain the fire detection and extinguishing systems, including zones, detectors, warnings and the actions required for an engine or cargo fire
Your checkpoint
A written systems fault-finding report of 12 scenarios (symptom given, system identified, cause and crew action stated), reviewed against the aircraft type notes
Aircraft Systems & Mass and Balance
Explain the principles of mass and balance, including datum, moment, arm, centre of gravity, and the calculation of CG position from a load sheet
Calculate the effect of loading changes (passengers, cargo, fuel burn) on CG and determine whether the result lies within the forward and aft limits
Explain the effect of forward and aft CG on stability, stall speed, cruise performance and fuel consumption, and state the reasons for forward and aft CG limits
Describe the standard load sheet and the meaning of dry operating mass, operating mass, take-off mass, landing mass and traffic load
Your checkpoint
Three complete load sheets calculated from scratch, each with a CG plot and a written statement of whether the loading is within limits and why
Advanced Aerodynamics & Aircraft Performance & Aircraft Systems
Consolidate all four domains by reworking every previously missed question and stating the underlying principle for each
Complete two full timed mock examinations under exam conditions and analyse the results by domain to identify the weakest two areas
Produce a one-page revision sheet per domain containing only the formulas, limits and failure actions most likely to be examined
Verify that all mass and balance calculations can be completed accurately and within time without reference notes
Your checkpoint
Two completed timed mock examinations with a written error analysis by domain and a final one-page revision sheet for each domain
