While already at high speed, what happens if Mach is allowed to increase?
a. airflow over parts of the airplane begins to exceed the speed of sound
b. shock waves can cause local airflow separation
c. characteristics such as pitch up, pitch down, or buffeting may occur
d. all of the above - ANS: d. All of the above

a. a high-speed stall and sudden pitch up
b. severe porpoising
c. a severe moment or 'Mach tuck' - ANS: c. A severe moment of "Mach tuck"
The speed of sound generally decreases with increasing altitude. This occurs because:
a. the air temperature decreases
b. the air pressure decreases
c. the composition of the air changes - ANS: a. The air temperature decreases.
Critical Mach number can be defined as:
a. the speed at which the aircraft is travelling faster than the speed of sound
b. the maximum mach number at which an aircraft may be safely operated
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 - ANS: 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:
a. the vertical fin
b. the rudder
c. An active stability augmentation system / yaw damper
d. pilot roll input - ANS: c. An active stability augmentation system / yaw damper.
Swept wings cause a significant:
a. an increase in effectiveness of flaps
b. reduction in effectiveness of flaps
c. flap actuation reliability issue - ANS: b. Reduction in effectiveness of flaps.
Why is convergence of Stall AOA and Mmo hazardous?
a. any decrease in airspeed will cause the aircraft to buffet and potentially stall
b. any increase in airspeed will cause the aircraft to buffet and potentially suffer mach tuck
c. airspeed changes may occur due to environmental factors, without pilot input
d. all of the above - ANS: d. All of the above
To maintain altitude in a banked turn, the lift produced by the airplane must be:
a. greater than the airplane weight, and the amount is a function of bank angle
b. greater than the airplane weight, and the amount is a function of altitude
c. equal to the weight of the airplane - ANS: 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:
a. the extra drag produced by the turn can lead to an excursion below L/D max
b. aircraft engines at higher altitudes produce less thrust to overcome drag
c. the aircraft will be operating closer to its buffet boundaries
d. all of the above - ANS: 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:
a. increasing thrust to arrest the slowdown
b. increasing thrust to accelerate to airspeed above L/D max speed
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 - ANS: 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.
Maximum Altitude is the highest altitude at which an airplane can be operated. Maximum Altitude for an airplane is:
a. maximum certified altitude - the altitude determined during certification set by the pressurisation structural load limits on the fuselage [Show Less]
