COMMERCIAL PILOT TEST PREP CHAPTER 1 QUESTIONS
AND VERIFIED DETAILED SOLUTIONS ( MULTIPLE
CHOICES) |100% CORRECT!!
By changing the AOA of a wing, the pilot can control the airplane's
A. lift, airspeed, and drag
B. lift, airspeed, and CG
C. lift, and airspeed, but not drag. Correct Answers A
An aircraft airfoil is designed to produce lift resulting from a difference
in the
A. negative air pressure below and a vacuum above the airfoil surface.
B. vacuum below the airfoil's surface and greater air pressure above the
airfoil's surface
C. higher air pressure below the airfoil's surface and lower air pressure
above the airfoil's surface Correct Answers C
The AOA of a wing directly controls the
A. angle of incidence of the wing
B. amount of airflow above and below the wing
C. distribution of pressures acting on the wing Correct Answers C
,In theory, if the AOA and other factors remain constant and the airspeed
is doubled, the lift produced at the higher speed will be
A.the same as at the lower speed
B. two times greater than at the lower speed
C. four times greater than at the lower speed. Correct Answers C
Which statement is true, regarding the opposing forces acting on an
airplane in steady-state level flight?
A. These forces are equal
B. Thrust is greater than drag and weight and lift are equal
C. Thrust is greater than drag and lift is greater than weight Correct
Answers A
To generate the same amount of lift as altitude is increased, an airplane
must be flown at
A. the same true airspeed regardless of AOA
B. a lower true airspeed and a greater AOA
C. a higher true airspeed for any given AOA Correct Answers C
What changes in airplane longitudinal control must be made to maintain
altitude while the airspeed is being decreased?
, A. increase the AOA to produce more lift than drag
B. increase the AOA to compensate for the decreasing lift
C. decrease the AOA to compensate for increasing drag Correct
Answers B
In theory, if the airspeed of an airplane is doubled while in level flight,
parasite drag will become
A. twice as great
B. half as great
C. four times greater Correct Answers C
In theory, of the airspeed of an aircraft in level flight is cut in half,
parasite drag will become
A. 1/3 as much
B. 1/2 as much
C. 1/4 as much Correct Answers C
As airspeed decreases in level flight below that speed for maximum L/D
ratio, the total drag of an airplane
A. decreases because of lower parasite drag
B. increases because of increased induce drag
