Module 11. Aeroplane aerodynamics, structures and systems
The type of fluid in an oleo strut will depend upon
•  the type of seal material.
•  heat generated in operation of the system.
•  type of fluid most readily available.

Trevordodd asking:
•  i thought the answer to this question was type of seal material, does anyone know why its heat generated in operation as the type of fluid may break the seal down.

•  change direction.
•  reflect.
•  change speed.

Richiegeee asking:
•  Will it not change direction too?

Module 7. Maintenance practices
At which frequency is the calibration of frequently used crimping tools carried out?
•  Bi-annually
•  Annually
•  Every 1000 crimps

marcoff asking:
•  How do I know when 1000 crimps were made?
The right answer should be every x time?

Module 12. Helicopter aerodynamics, structures and systems
The stalling speed of an helicopter blade
•  does not change.
•  is increased when the helicopter is heavier.
•  is increased when the helicopter is lighter.

YukonGhetto asking:
•  Blade stall is more likely when the HC is heavier. Does that not mean that the stalling speed of the blade is increased when the HC is lighter and will stall at a lower speed when the HC is heavier? Just getting ready for my A3 and this is confusing me!
