SOLUTION
Which of the following statements regarding energy is true? 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:
Answer - d. All of the above
What is the effect on total drag if airspeed slows below L/D Max? Answer - c.
Drag increases because of increased induced drag.
A jet pilot flying at L/D Max will obtain best: Answer - b. Endurance
When a jet aircraft is flown at the appropriate airspeed for maximum range,
which type of drag predominates? Answer - a. Parasite
While already at high speed, what happens if Mach is allowed to increase?
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? Answer - c. A severe
moment of "Mach tuck"
, The speed of sound generally decreases with increasing altitude. This occurs
because: Answer - a. The air temperature decreases.
Critical Mach number can be defined as: 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:
Answer - c. An active stability augmentation system / yaw damper.
Swept wings cause a significant: Answer - b. Reduction in effectiveness of flaps.
Why is convergence of Stall AOA and Mmo hazardous? Answer - d. All of the
above
To maintain altitude in a banked turn, the lift produced by the airplane must
be: 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: 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: Answer - c. Increasing thrust to maximum available
thrust and reducing bank angle while accelerating to airspeed above L/D Max
