ATPL P.O.F EXAM 1 SEM 1 LIFT
QUESTIONS AND ANSWERS
1. To maintain altitude, what must be done as Indicated Airspeed (IAS) is reduced? -
Correct Answers -b. Increase angle of attack to maintain the correct lift force.
2. If more lift force is required because of greater operating weight, what must be done
to fly at the angle of attack which corresponds to CLMAX? - Correct Answers -d.
Increase the Indicated Airspeed (IAS).
3. Which of the following statements is correct?
1. To generate a constant lift force, any adjustment in IAS must be accompanied by a
change in angle of attack.
2. For a constant lift force, each IAS requires a specific angle of attack.
3. Minimum IAS is determined by CLMAX.
4. The greater the operating weight, the higher the minimum IAS. - Correct Answers -d.
1, 2, 3 and 4.
4. What effect does landing at high altitude airports have on ground speed with
comparable conditions relative to temperature, wind and aeroplane weight? - Correct
Answers -a. Higher than at low altitude.
5. What flight condition should be expected when an aircraft leaves ground effect? -
Correct Answers -b. An increase in induced drag and a requirement for a higher angle
of attack.
6. If the angle of attack and other factors remain constant and airspeed is doubled, lift
will be: - Correct Answers -b. four times greater.
7. What true airspeed and angle of attack should be used to generate the same amount
of lift as altitude is increased? - Correct Answers -a. A higher true airspeed for any given
angle of attack.
8. How can an aeroplane produce the same lift in ground effect as when out of ground
effect? - Correct Answers -a. A lower angle of attack.
9. By changing the angle of attack of a wing, the pilot can control the aeroplane's: -
Correct Answers -c. lift, airspeed, and drag.
