Module 8. Basic aerodynamics
Mach trim operates
•  along the longitudinal axis.
•  along the lateral axis.
•  to reduce Dutch roll.

paulofly@yahoo.com asking:
•  It´s correct?

Module 12. Helicopter aerodynamics, structures and systems
The coning angle of the rotor blades is the angle between
•  the horizontal and the rotor blades.
•  the rotor blades and the tip path plane.
•  the normal axis and the rotor blades.

Jordi asking:
•  I think this is also wrong.It should be horizontal plane and tip oath od the blades.

Module 12. Helicopter aerodynamics, structures and systems
Solidity of the rotor is the ratio of the
•  blade area to disc area.
•  all up weight to blade area.
•  all up weight to disc area.

Jordi asking:
•  This question has a 100% wrong answer.It should be the opposite .The correct term is solidity=disk area/blade area.

Module 12. Helicopter aerodynamics, structures and systems
A redundant structure is
•  on-condition structure.
•  a safe-life structure.
•  a failsafe structure.

Jordi asking:
•  why not safe life?

Module 12. Helicopter aerodynamics, structures and systems
In straight and level flight, the forward air speed is controlled by the
•  cyclic stick and the throttle.
•  the cyclic stick and the collective lever.
•  collective lever and the throttle.

Jordi asking:
•  Shouldn't it be collective with throttle?
