Which of the following statements regarding energy is true?
- correct answer d. Kinetic energy can be traded for potential energy, and potential energy can be
traded for kinetic energy
The objective in maneuvering the airplane is to manage energy so that:
- correct answer d. All of the above
What is the effect on total drag if airspeed slows below L/D Max?
- correct answer c. Drag increases because of increased induced drag.
A jet pilot flying at L/D Max will obtain best:
- correct answer b. Endurance
When a jet aircraft is flown at the appropriate airspeed for maximum range, which type of drag
predominates?
- correct answer a. Parasite
While already at high speed, what happens if Mach is allowed to increase?
- correct answer d. All of the above
, What is the result of a shock-induced separation of airflow occurring symmetrically near the wing root
of a swept wing aircraft?
- correct answer c. A severe moment of "Mach tuck"
The speed of sound generally decreases with increasing altitude. This occurs because:
- correct answer a. The air temperature decreases.
Critical Mach number can be defined as:
- correct answer c. The speed of an aircraft in which airflow over any part of the aircraft or structure first
reaches, but doesn't exceed Mach 1.0.
Stability in the vertical axis tends to drive the sideslip angle toward zero. The most dynamic stability
about the vertical axis on modern jet transports is from:
- correct answer c. An active stability augmentation system / yaw damper.
Swept wings cause a significant:
- correct answer b. Reduction in effectiveness of flaps.
Why is convergence of Stall AOA and Mmo hazardous?
- correct answer d. All of the above
To maintain altitude in a banked turn, the lift produced by the airplane must be:
- correct answer a. Greater than the airplane weight, and the amount is a function of bank angle.
Excessive bank angles at high altitudes can be hazardous because:
- correct answer d. All of the above
When operating at constant speed with constant thrust setting at high altitude (typically above FL250) in
slow flight below L/D Max airspeed, any disturbance causing a decrease in airspeed will result in a
further decrease in airspeed unless thrust in increased. High altitude recovery from slow flight while
turning is best accomplished by:
- correct answer c. Increasing thrust to maximum available thrust and reducing bank angle while
accelerating to airspeed above L/D Max speed. In a thrust limited situation, exiting slow flight will
require an immediate descend as an aerodynamic stall is imminent.
