Assistant Flight
1. Which force acts opposite to thrust in steady level flight?
A. Lift
B. Drag
C. Weight
D. Centripetal force
B. Drag. Drag opposes the forward motion of the aircraft, while lift
opposes weight.
2. The angle between the chord line of a wing and the relative airflow is
called the
A. angle of attack
B. angle of incidence
C. dihedral angle
D. sweep angle
A. angle of attack. Angle of attack is measured between the chord line
and the oncoming relative wind.

,3. An aerofoil stalls when
A. airspeed falls below 60 knots
B. the engine loses power
C. the critical angle of attack is exceeded
D. the flaps are retracted
C. the critical angle of attack is exceeded. A stall is caused by airflow
separation at the critical angle of attack, whatever the speed or attitude.
4. The load factor in a level 60° banked turn is approximately
A. 1.4 g
B. 1.15 g
C. 3.0 g
D. 2.0 g
D. 2.0 g. Load factor equals 1 divided by the cosine of the bank angle,
which is 2.0 at 60°.
5. Stalling speed will increase when
A. the aircraft becomes lighter
B. flaps are extended fully
C. the aircraft descends to a lower altitude
D. load factor increases
D. load factor increases. A higher load factor, as in a steep turn, raises
the stall speed by the square root of that factor.
6. Induced drag is greatest at
A. low speed and high angle of attack
B. high speed and low angle of attack
C. cruise speed only
D. the speed of minimum drag only
A. low speed and high angle of attack. Induced drag is a by-product of
lift and is highest when flying slowly at high angles of attack.

,7. Parasite drag varies approximately with
A. the inverse of airspeed
B. the square of the airspeed
C. the angle of attack only
D. aircraft weight
B. the square of the airspeed. Doubling the airspeed quadruples parasite
drag.
8. Flying at the speed for maximum lift-to-drag ratio gives the
A. best rate of climb
B. lowest stall speed
C. best glide distance in still air
D. greatest load factor
C. best glide distance in still air. At L/D max the aircraft covers the
greatest distance per unit of height lost.
9. Ground effect causes
A. an increase in induced drag
B. a reduction in induced drag
C. a higher stalling speed
D. a reduction in lift at a given angle
B. a reduction in induced drag. Near the surface, wingtip vortices are
weakened, which reduces induced drag.
10. Washout is built into a wing so that
A. the tip stalls before the root
B. top speed is increased
C. parasite drag is removed
D. the root stalls before the tip
D. the root stalls before the tip. A lower incidence at the tip keeps
aileron control effective when the root stalls first.

, 11. Adverse yaw is mainly caused by
A. engine torque reaction
B. propeller slipstream
C. the gyroscopic effect
D. greater induced drag on the wing with the downward-deflected
aileron
D. greater induced drag on the wing with the downward-deflected
aileron. The wing producing more lift also produces more induced drag,
yawing the nose away from the turn.
12. Which control surface primarily controls movement about the
longitudinal axis?
A. Elevator
B. Rudder
C. Trim tab
D. Ailerons
D. Ailerons. Ailerons produce roll about the longitudinal axis.
13. Movement about the lateral axis is called
A. roll
B. yaw
C. pitch
D. spin
C. pitch. Pitch is rotation about the lateral axis and is controlled by the
elevator.
14. Positive static stability means that after a disturbance the aircraft
A. continues to move away from it
B. stays in the new attitude
C. oscillates with growing amplitude
D. tends to return toward its original attitude
D. tends to return toward its original attitude. Positive static stability
produces an initial tendency to return to equilibrium.
