What is used in some wings to improve its lateral stability?
- Wing twist
- Wing dihedral
- Angle of incidence - ANS_Wing Dihedral
During powered flight of a helicopter, the direction of airflow through the rotor is...
- At right angles to the rotor
- From top to bottom
- From bottom to top - ANS_From top to bottom
A condition which causes a single main rotor helicopter to drift in the direction of the tail rotor thrust is
referred to as...
- Ground effect
- Translational lift
- Translating tendency - ANS_Translating tendency
Which trailing edge flap system increases wing area?
, - Fowler flaps
- Krueger flaps
- Slotted flaps - ANS_Fowler flaps
Pilot pulls aft on the control column, while rotating the control wheel clockwise:
- Nose will pitch up, and the aircraft will roll to the right
- Nose will pitch down, and the aircraft will roll to the right
- Nose will pitch down, left aileron will move up, the right aileron will move down, causing the aircraft to
roll left - ANS_Nose will pitch up, and the aircraft will roll to the right
By turning the control wheel counter-clockwise:
- The left aileron will deflect down the right will deflect up causing the aircraft to roll to the right
- The left aileron will deflect down the right will deflect up causing the aircraft to rol to the left
- The left aileron will deflect up the right will deflect down causing the aircraft to roll to the left -
ANS_The left aileron will deflect up and the right will deflect down causing the aircraft to roll to the left
What aircraft structure gives the aircraft directional stability?
- Horizontal stabilizer
- Elevator
- Vertical Stabilizer - ANS_Vertical Stabilizer
The additional lift produced by the helicopter main rotor system as it enters horizontal flight is referred
to as...
