2. Where can you best determine the effects of flaps on stall speeds?

3. What is Vso?

4. What is Vs1(subscript)?

5. What is Va?

6. What is load factor?

7. What can occur in a constant rate turn in which the angle of bank is allowed to increase?

8. What is the effect on the elevator if flown with an aft CG?

9. What happens to stall speed with increases in weight?

10. What changes occur in an aircraft's indicated stall speed with an increase in altitude?

11. How can a pilot protect the aircraft from turbulence caused stall?

12. When are stalls resulting from improper airspeed management most likely to occur?

13. What is the key procedure required to initiate a stall recovery?

14. What is the cause of a secondary stall?

15. What is the maneuver in which an aircraft descends in a helicial path while flying at greater than the critical AOA?

16. How is an incipient spin distinguished from a fully developed steady state spin?

17. How is the pitch attitude of a spin different from that of a flat spin?

18. What is the most distinguishing characteristic of a spiral from a spin?


Answer
1. The stall is the result of excessive angle of attack, not insufficient airspeed.
2. You can best determine flap effects on stalls by reference to the airspeed indicator markings.

---The power-off stall in landing configuration is the low end of the white arc

---The power-off stall in clean configuration is the low end of the green arc.

3. Vso is the stall speed or minimum steady flight speed possible in a landing configuration

4. Vs1 (subscript) is the stall speed or minimum steady flight speed in a specified configuration.

5. Va is the design maneuvering speed. The speed above which full or abrupt control movements may result in structural damage.

6. Load Factor is the ratio of the lifting force produced by the wings to the actual weight of the aircraft including its contents. Load factors are expressed in G's.

7. The increase load factors of the steeper banks will cause an increase in the stall speed.

8. An aft CG causes elevator forces required for movement to be very light. Light elevator forces can cause over-control and abrupt stall entries that may be unrecoverable.

9. As weight increases so does the indicated stall speed.

10. There is little effect in indicated stall speed with changes in altitude.

11. Flying as fast as possible below Va is a protection against turbulence caused stalls.

12. Distraction of the pilot is the most common cause of airspeed management related stalls.

13. The key factor in recovering from a stall is regaining control by reducing the AOA.

14. Hurrying the completion of the primary stall most likely causes a secondary stall.

15. This is the basic definition of a spin.

16, The spin is distinguished from the incipient spin by the addition of an established rotation.

17, A spin has a marked nose down attitude. A flat spin is near level in pitch and roll.

18. Instrument readings are essentially the same except for the higher and increasing airspeed of the spiral. A spin is a low airspeed maneuver except after recovery.

Question
1. A landing on a narrower than usual runway will give what sensations?

2. What is autokinesis?

3. How might a runway in featureless terrain appear?

4. What illusion occurs at night during rapid acceleration?

5. An abrupt level off from a climb at night causes what illusion?

6. What visual hazard exists when flying on a clear night?

7. What landing incident is likely to occur when landing in heavy rain?

8. What illusion occurs if you move your head during a turn?

Answers:

1. A narrow runway gives the impression that you are higher than you are above the runway.
2. Autokinesis is a visual illusion at night where a single light seems to move when stared at.

3. The relative height distance between aircraft and runway will appear greater than it is.

4. The somatogravic illusion occurs giving a sense of extreme nose-high attitude when accelerating along the ground without outside cues.

5. The inversion illusion occurs when a night or in the cloud climb returns to level flight. This sensation makes you feel as though you were tumbling backwards.

6. On a clear night lighted object appears farther away and higher than it is.

7. Windshield rain gives an illusion of height. Aircraft tend to land short of the runway.

8. A rapid head movement during a turn may cause the coriolis illusion which may be a sense of pitching up or down, or rolling left or right.

 Questions

1. What defines the angle between the wing chord line and the relative wind?

2. Probable cause of high oil temperature and cylinder head temperatures above normal is?

3. What is the probable cause of a rough engine during carburetor heat check?

4. You have leaned at 10,000' for best operation. You descend to 4000' without any mixture adjustment. What happens?

5. How does C.H affect the mixture setting?

6. How can you make the engine to continue to operate if you have leaned, applied C.H. and leaned still further till the engine barely operates?

7. What is probable cause for engine to exceed its normal operating temperatures?

8. High engine temperatures can be related to what oil condition?
9. What is the purpose of making your first clearing turn to the left?
10. A pilot who services the wheel bearings of an aircraft is considered to be doing what?

11. Weather forecasts covering several states is called an…?

12. A red rectangle with a centered white circle with a white - inside means…?

13. What is the significance of a large area covered with evenly spaced diagonal yellow lines?

14. What illusions occur when flying in and out of clouds?

15. What illusion occurs due to reflected light on the canopy?

16. In a high density situation, what could cause a carburetor heat check fail to show a drop in rpm or power?

Answers

1. The angle of attack is defined as the angle between the wing chord line and the relative wind.

2. Excessive power on a lean mixture causes high engine operating temperatures.

3. Lean mixture and run another C.H. check.

4. Your aircraft will be running on an excessively lean mixture.
5. The addition of hot air enriches the mixture.

6. Pumping the primer will make the engine continue to put out power.
7. Use of a fuel that is less than required fuel specifications will cause excess temperatures.
8. High engine temperatures can be caused by low oil level.

9. You should make your first clearing turns to the left because following traffic will be passing to your right.
10. Servicing wheel bearings is considered to be pilot authorized preventative maintenance.
11. Area forecasts cover weather conditions over several states.

12. Red rectangle with white circle and white - inside identifies paved area where aircraft are prohibited.

13. This is a 'taxiway ending marker and says that the taxiway stops at the intersection.

14. Flying in and out of clouds make it appear that you are climbing and changing speeds.

15. Reflected canopy light make is appear as though the airplane is in a steep turn and lower than it is.

16. A well leaned mixture can cause a carburetor heat check not to show a drop.
