PRIVATE PILOT PRACTICE QUESTIONS
AND ACCURATE ANSWERS GRADED A+
●● Under what number may information about Air Traffic Control and
General Operations be found in the Advisory Circular?
Answer: Under subject 90
●● Under what number may information about Airmen be found in the
Advisory Circular?
Answer: Under subject 60
●● Under what number may information about Airspace be found in the
Advisory Circular?
Answer: Under subject 70
●● Changes in the center of pressure of a wing affect the aircraft's
Answer: Aerodynamic balance and controllability.
The center of pressure (CP) changes with the angle of attack. The plane's
aerodynamic balance and controllability are governed by changes in the
center of pressure.
●● An airplane said to be inherently stable will...
,Answer: require less effort to control.
●● When does P-factor cause the airplane to yaw to the left?
Answer: When at high angles of attack.
Asymmetric propeller loading (or P-factor) occurs when the airplane is
at a high angle of attack (AOA).
●● What is Bernoulli's principle?
Answer: Air traveling faster over the curved upper surface of an airfoil
causes lower pressure on the top surface.
●● What is the critical angle of attack?
Answer: The point at which the wing will stall.
If the speed decreases enough, the required AOA will increase to the
critical AOA. Any further increase in AOA will result in the wing
stalling.
●● In the following image, the horizontal dashed line from point C to
point E represents the...
Answer: positive limit load factor.
,This figure is a VG diagram. The line C to E represents the maximum
load factor for the airplane. Flight beyond this may cause structural
damage.
●● What is parasite drag?
Answer: The drag caused by the fuselage and other protrusions
disrupting the flow of air.
Parasite drag is composed by all of the forces that work to slow an
aircraft's movement.
●● In what flight condition is torque effect the greatest in a single-
engine airplane?
Answer: Low airspeed, high power, and high angle of attack.
Torque effect is the influence of engine torque on aircraft movement and
control. It is generally exhibited as a left turning tendency in piston
single engine propeller driven aircraft.
●● What are the four forces that act on an airplane in equilibrium?
Answer: Lift, Thrust, Weight, and Drag
●● Define the term "Angle of Attack."
, Answer: The acute angle formed between the chord line of an airfoil and
the direction of the air striking the airfoil.
●● A standard rate turn is defined as...
Answer: a turn rate of 3^o per second.
The turn coordinator only indicates the rate and direction of a turn; it
does not display the angle of bank.
●● When an aircraft is flying at a high angle of attack, the downward
moving blade of the propeller has a higher resultant velocity, creating
more lift than the upward moving blade, causing...
Answer: the airplane's nose to pull to the left.
●● The left turning tendency of an airplane caused by P-factor is the
result of the...
Answer: propeller blade descending on the right, producing more thrust
than the ascending blade on the left.
●● T or F - Form drag increases as airspeed increases.
Answer: True.
Form drag is the portion of parasite drag, generated by the aircraft due to
its shape and airflow around it and increases with velocity.
