and Correct Answers
Which of the following statements regarding energy is true?
d. Kinetic energy can be traded for potential energy, and potential energy can be traded for
kinetic energy
What is the effect on total drag if airspeed slows below L/D Max?
c. Drag increases because of increased induced drag.
A jet pilot flying at L/D Max will obtain best:
b. Endurance
When a jet aircraft is flown at the appropriate airspeed for maximum range, which type of drag
predominates?
a. Parasite
What is the result of a shock-induced separation of airflow occurring symmetrically near the
wing root of a swept wing aircraft?
,c. A severe moment of "Mach tuck"
The speed of sound generally decreases with increasing altitude. This occurs because:
a. The air temperature decreases.
Critical Mach number can be defined as:
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. An active stability augmentation system / yaw damper.
Swept wings cause a significant:
b. Reduction in effectiveness of flaps.
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.
, Excessive Bank Angles At High Altitudes Can Be Hazardous Because:
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:
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:
E. The Lowest Of The Above Listed Altitudes.
Exceed The Critical Angle Of Attack And The Surface Will Stall, And Lift Will Decrease Instead Of
Increasing. This Is True:
D. Regardless Of Airplane Speed Or Attitude.
Which Of The Following Statements Is True?
D. Recovery From Approach To Stall Warning Is The Same As Recovery From A Stall.
