Which of the following statements regarding energy is true?
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:
What is the effect on total drag if airspeed slows below L/D Max?
A jet pilot flying at L/D Max will obtain best:
Endurance
When a jet aircraft is flown at the appropriate airspeed for maximum range, which type of drag predominates?
While already at high speed, what happens if Mach is allowed to increase?
What is the result of a shock-induced separation of airflow occuring symmetrically near the wing root of a swept wing aircraft?
The speed of sound generally decreases with increasing altitude. This occurs because:
Critical Mach number can be defined as:
Stability in the vertical axis tends to drive the sideslip ange toward zero. The most dynamic stability about the vertical axis on modern jet transports is from:
Swept wings cause a dignificant:
reduction in effectiveness of flaps.
Why is convergence of Stall AOA and Mmo hazardous?
To maintain alitude in a banked turn, the lift produced by the airplane must be:
Excessive bank angles at high altitudes can be hazardous because:
When operating at a constant airspeed 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 is increased. High altitude recovery from slow flight while turning is best accomplished by:
Increasing thrust to accelerate to airspeed above L/D max speed. –
while accelerating to airspeed above L/D Max speed. In a thrust limited
situation, exiting slow flight will require an immediate descent as an
aerodynamic stall is imminent.
