Distinguish primary from secondary flight controls and explain the function of flaps, slats, spoilers, trim tabs and balance tabs, including mass balance and flutter prevention.

Explain the purpose of structural inspection items such as stress corrosion, fatigue cracking and lightning-strike bonding in airframe construction.

Describe the layout and function of a typical hydraulic system: reservoir, filters, engine-driven and electric pumps, accumulators, pressure relief and selector valves, and actuators.

Explain how accumulator pre-charge provides emergency pressure and damps pressure surges, and interpret typical hydraulic system indications such as pressure, quantity and low-pressure warning.

Explain brake system operation from pedal input through master cylinders or power brake valves to brake units, and describe the role of anti-skid systems and their wheel speed sensors.

State the inspection and servicing considerations for landing gear, tyres, wheels and brakes, including tyre creep, wear limits and hydraulic fluid contamination.

Describe the configuration of horizontally opposed and inline piston engines, naming the major components of the crankcase, crankshaft, connecting rods, pistons, cylinders, valves and valve train.

Explain the four-stroke cycle and the induction system, including carburettor venturi operation, mixture control, carburettor icing and the purpose of carburettor heat.

Describe fuel injection and ignition systems, including magnetos, spark plugs, ignition timing and the reason for dual ignition.

Explain lubrication and cooling in piston engines, covering oil pumps, oil coolers, pressure and scavenge flow, and air cooling with cylinder fins and baffles.

Explain propeller theory including blade angle, angle of attack, pitch, slip, thrust and centrifugal loads, and describe constant-speed unit operation, feathering and synchronising.

Describe propeller icing and the protection methods used, and explain the effect of ice on thrust and vibration.

Describe the construction and function of the compressor, combustion chamber and turbine sections of a gas turbine engine, and explain how each stage contributes to thrust.

Explain gas turbine lubrication and starting, including starter types, ignition sequence, light-up indications and the parameters monitored during start.

Describe thrust augmentation methods and the differences between turbojet, turbofan, turboprop and turboshaft configurations.

Explain DC and AC generation on aircraft, including generators, alternators, voltage regulators, bus bars and distribution, and describe battery types and their care.

Explain circuit protection devices including fuses, circuit breakers and current limiters, and state when each is used.

Describe the sources of pneumatic power on an aircraft, including engine bleed, compressors and ground carts, and explain how bleed air is regulated and protected against overpressure and overheat.

Explain the operation of the air-conditioning system, including the air cycle machine, heat exchangers, water separation and temperature control, and describe cabin pressurisation with outflow valves and pressure controllers.

Describe the layout of fuel tanks, including integral, bladder and rigid types, and explain venting, baffles and the reasons for fuel imbalance limits.

Explain fuel pump types, selector and shut-off valves, cross-feed operation and the meaning of quantity and flow indications in the cockpit.

Explain fuel management considerations including contamination, water and sediment checks, fuel grade and the effect of temperature on fuel.

Describe ice protection methods for airframe, propeller, pitot and static systems, distinguishing anti-icing from de-icing and thermal, chemical and pneumatic approaches.

Explain rain protection including windscreen wipers and rain repellent, and state the limitations imposed on operations in heavy rain.

Describe fire detection methods such as heat, smoke and rate-of-rise detectors, and explain the operation of fire extinguishing systems including agent types, bottles, squibs and discharge indication.

Explain oxygen system types, including gaseous and chemical generators, masks, regulators and the pre-flight checks required.

Revisit propeller icing and synchronising, and explain how propeller ice affects engine operation and what the pilot does about it.

Re-derive from memory the load paths and control chain from week 1, and correct any gaps found.

Re-explain hydraulic system components and indications, and solve at least 10 numerical or sequencing problems on pressure, accumulator pre-charge and actuator travel.

Re-explain landing gear, brake and anti-skid operation, and describe at least five failure modes with their cockpit indications and pilot actions.

Integrate airframe, hydraulic and gear knowledge by describing how a gear-door or flap hydraulic failure affects aircraft handling and what limitations apply.

Complete a timed mixed review covering all ten domains, weighting time in proportion to the published domain percentages.

Re-explain from memory the five highest-risk topics identified by your earlier test scores, without notes.

State the key limitations, warnings and normal operating figures for each system studied, in a single consolidated list.

Identify remaining weak areas and write a short revision list to carry into final exam preparation.
