Unit 1 Flashcards
(20 cards)
Angle of Attack is the angle between?
The chord line and relative wind
The angle of attack at which the airplane stalls
Is always the same and depends on the airfoil design
Induced drag is the result of
Generation of lift
Parasite drag is affected as follows by airspeed
As airspeed increases, parasite drag increases
To clear obstacles close to the departure end of the runway climb at
Vx
Adverse yaw during turn is caused by
Increased drag on the high wing
During a turn a steeper bank angle will result in
Increased rate of turn
The purpose of the elevator trim is to
Relieve the control pressures the pilot must hold
The function of the flaps is to
Allow flight at slower airspeed
If the ball in the turn and bank indicator is displaced to the right during a right turn
Increase right rudder input
During engine failure in flight, the best glide airspeed is the airspeed that results in
The longest glide distance
An airplane with CG close to its aft limit
Is less stable
To gain the most altitude in a specified time you must climb at
Vy
Ground effect when flying close to the ground is caused by
Change of the effective relative wind which results in less induced drag and increased lift
While taxiing you observe the wind is blowing from your front left. The controls must be held as follows
Yoke to the left, right ailerons down left up ( turn into the wind)
For the airplane to maintain constant speed climb
There must be excess power available than what is required for cruise flight
The force that causes an airplane to turn is
The horizontal component of lift resulting from banking
The direction of relative wind is
Opposite to the flight path
Takeoff and landing is accomplished into wind to
Allow us to develop the requires lift at slow ground speed
Wing washout refers to the
Decreasing angle of incidence from root to wingtip
