Aircraft/Aerodynamics Quiz #2

There are at least 2 ways to practice this quiz. One way is to check your answer by clicking the "Check answer" button. This will give you immediate feedback regarding specific questions. The other option is to simply answer all the questions as a test and "Flip the switch" or "Press the button" (grade the test) after the last question to receive a test score. You can then check each question individually to see which questions were missed. If you have any problems or suspect an error, feel free to contact me anytime.

Thank you and good luck.

1. How can turbulent air cause an increase in stalling speed of an airfoil?

An abrupt change in relative wind.
A decrease in angle of attack.
Sudden decrease in load factor.

2. What effect does an increase in airspeed have on a coordinated turn while maintaining a constant angle of bank and altitude?

The rate of turn will decrease resulting in a decreased load factor.
The rate of turn will increase resulting in an increased load factor.
The rate of turn will decrease resulting in no changes in load factor.

3. What is the effect on total drag of an aircraft if the airspeed decreases in level flight below that speed for maximum L/D?

Drag increases because of increased induced drag.
Drag increases because of increased parasite drag.
Drag decreases because of lower induced drag.

4. What is load factor?

Lift multiplied by the total weight.
Lift subtracted from the total weight.
Lift divided by the total weight.

5. What affects indicated stall speed?

Weight, load factor, and power.
Load factor, angle of attack, and power.
Angle of attack, weight, and air density.

6. If no corrective action is taken by the pilot as angle of bank is increased, how is the vertical component of lift and sink rate affected?

Lift increases and the sink rate increases.
Lift decreases and the sink rate decreases.
Lift decreases and the sink rate increases.

7. Why must the angle of attack be increased during a turn to maintain altitude?

Compensate for loss of vertical component of lift.
increase the horizontal component of lift equal to the vertical component.
Compensate for increase in drag.

8. How can the pilot increase the rate of turn and decrease the radius at the same time?

Steepen the bank and increase airspeed.
 Steepen the bank and decrease airspeed.
Shallow the bank and increase airspeed.

9. What is the relationship of the rate of turn with the radius of turn with a constant angle of bank but increasing airspeed?

Rate will decrease and radius will increase.
Rate will increase and radius will decrease.
Rate and radius will increase.

10. Upon which factor does wing loading during a level coordinated turn in smooth air depend?

Rate of turn.
Angle of bank.
True airspeed.

11. If an aircraft with a gross weight of 2,000 pounds were subjected to a total load of 6,000 pounds in flight, the load factor would be

2 G's.
3 G's.
9 G's.

12. Airflow separation over the wing can be delayed by using vortex generators,

directing high pressure air over the top of the wing or flap through slots and making the wing surface smooth.
directing a suction over the top of the wing or flap through slots and making the wing surface smooth.
making the wing surface rough and/or directing high pressure air over the top of the wing or flap through slots.

13. In a light, twin-engine airplane with one engine inoperative, when is it acceptable to allow the ball of a slip-skid indicator to be deflected outside the reference lines?

While maneuvering at minimum controllable airspeed to avoid overbanking.
When operating at any airspeed greater than VMc.
When practicing imminent stalls in a banked attitude.

14. What is the safest and most efficient takeoff and initial climb procedure in a light, twin-engine airplane? Accelerate to

best engine-out, rate-of-climb airspeed while on the ground, then lift off and climb at that speed.
VMC, then lift off at that speed and climb at maximum angle-of-climb airspeed.
an airspeed slightly above VMC, then lift off and climb at the best rate-of-climb airspeed.

15. What procedure is recommended for an engineout approach and landing?

The flightpath and procedures should be almost identical to a normal approach and landing.
The altitude and airspeed should be considerably higher than normal throughout the approach.
A normal approach, except do not extend the landing gear or flaps until over the runway threshold.

16. What performance should a pilot of a light, twin- engine airplane be able to maintain at Vc?

Heading.
Heading and altitude.
Heading, altitude, and ability to climb 50 ft/min.

17. What criteria determines which engine is the "critical" engine of a twin-engine airplane?

The one with the center of thrust closest to the centerline of the fuselage.
The one designated by the manufacturer which develops most usable thrust.
The one with the center of thrust farthest from the centerline of the fuselage.

18. What effect, if any, does altitude have on Vc for an airplane with unsupercharged engines?

None.
Increases with altitude.
Decreases with altitude.

19. Under what condition should stalls never be practiced in a twin-engine airplane?

With one engine inoperative.
With climb power on.
With full flaps and gear extended.

20. What does the blue radial line on the airspeed indicator of a light, twin-engine airplane represent?

Maximum single-engine rate of climb.
Maximum single-engine angle of climb.
Minimum controllable airspeed for single-engine operation.
