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. Identify the type stability if the aircraft attitude remains in the new position after the controls have been neutralized.

Negative longitudinal static stability.
Neutral longitudinal dynamic stability.
Neutral longitudinal static stability.

2. What is a characteristic of longitudinal instability?

Pitch oscillations becoming progressively greater.
Bank oscillations becoming progressively greater.
Aircraft constantly tries to pitch down.

3. Describe dynamic longitudinal stability.

Motion about the longitudinal axis.

4. What is the reason for variations in geometric pitch along a propeller or rotor blade?

it permits a relatively constant angle of attack along its length when in cruising flight.
It prevents the portion of the blade near the hub or root from stalling during cruising flight.
It permits a relatively constant angle of incidence along its length when in cruising flight.

5. If an engine failure occurs at an altitude above single-engine ceiling, what airspeed should be maintained?

Positive static stability.
Neutral dynamic stability.

10. What effect does landing at high elevation airports have on groundspeed with comparable conditions relative to temperature, wind, and airplane weight?

Higher than at low elevation.
Lower than at low elevation.
The same as at low elevation.

11. What flight condition should be expected when an aircraft leaves ground effect?

An increase in induced drag requiring a higher angle of attack.
A decrease in parasite drag permitting a lower angle of attack.
An increase in dynamic stability.

12. What characteristic should exist if an airplane is loaded to the rear of its CG range?

Sluggish in aileron control.
Sluggish in rudder control.
Unstable about the lateral axis.

13. What will be the ratio between airspeed and lift if the angle of attack and other factors remain constant and airspeed is doubled? It will be

the same.
two times greater.
four times greater.

14. What true airspeed and angle of attack should be used to generate the same amount of lift as altitude is increased?

The same true airspeed and angle of attack.
A higher true airspeed for any given angle of attack.
A lower true airspeed and higher angle of attack.

15. How can an airplane produce the same lift in ground effect as when out of ground effect?

The same angle of attack.
A lower angle of attack.
A higher angle of attack.

16. What are some characteristics of an airplane loaded with the CG at the aft limit?

Lowest stall speed, highest cruise speed, and least stability.
Highest stall speed, highest cruise speed, and least stability.
Lowest stall speed, lowest cruise speed, and highest stability.

17. Which maximum range factor decreases as weight decreases?

Altitude.
Airspeed.

18. By changing the angle of attack of a wing, the pilot can control the airplane's

lift, gross weight, and drag.

Maximum range and distance glide.
Best angle of climb.
Maximum endurance.

20. The primary purpose of high-lift devices is to increase the

L/D_max
lift at low speeds.
drag and reduce airspeed.
