- knowledge of range and endurance flying
- wing design – anhedral, dihedral, aspect ratio, wash-out
- factors affecting aircraft stability
- flow dynamics – pressure changes with changes in angles of attack
- take-off and landing – ‘ground effect’ and how it effects aeroplane performance.

Subject feedback for previous years
Most topics have been well handled. However a higher than expected percentage of candidates appears to be inadequately prepared in the following areas:
- Spoilers and vortex generators
- Knowledge of range and endurance flying
- Wing design – anhedral, dihedral, aspect ratio, wash-out
- Factors affecting aircraft stability
- Flow dynamics – pressure changes with changes in angles of attack
- Take-off and landing – ‘ground effect’ and how it effects aeroplane performance
