While already at high speed, what happens if Mach is allowed to increase?
a. Airflow over parts of the airplane begin 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 Correct Ans-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?
, ATP-CTP course test Questions and Answers
a. A high-speed stall and sudden pitch-up
b. Severe porpoising.
c. A severe moment or "Mach Tuck". Correct Ans-c. A severe moment or "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. Correct Ans-a. The air temperature decreases.
Critical Mach number can be defined as:
a. The speed at which the aircraft is traveling faster than 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 Correct 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:

C. Chemical energy stays above certain thresholds (not running out of fuel)
D. All of the above Correct Ans-D. All of the above
What is the effect on total drag if airspeed slows below L/DMax?
A. Drag increases because of increased parasite drag.
B. Drag decreases because of lower induced drag.
C. Drag increases because of increased induced drag. Correct Ans-C. Drag increases
because of increased induced drag
A jet pilot flying at L/DMax will obtain best:
A. Range
B. Endurance
C. Ride Quality Correct Ans-B. Endurance
