PRIVATE PILOT: FAA WRITTEN EXAM
QUESTIONS AND ANSWERS UPDATED
(2024/2025) (VERIFIED ANSWERS)
Trim systems are designed to do what? - ANS ✓They relieve the pilot of the
need to maintain constant back pressure on the flight controls
The four forces acting on an airplane in flight are: - ANS ✓Lift, Weight,
Thrust, and Drag
When are the four forces that act on an airplane in equilibrium? - ANS
✓During unaccelerated flight
What is the relationship of lift, drag, thrust, and weight when the airplane is
in straight-and-level flight? - ANS ✓Lift equals weight
Thrust equals drag
Which statement relates to Bernoulli's principle? - ANS ✓Air traveling faster
over the curve upper surface of an airfoil causes lower pressure on the top
surface
The term "angle of attack" is defined as the angle... - ANS ✓Between the wing
chord line and the relative wind
Angle of attack is defined as the chord line of an airfoil and the... - ANS
✓Direction of the relative wind

The angle of attack at which an airplane wing stalls will... - ANS ✓Remain the
same regardless of gross weight
As altitude increases, the indicated airspeed at which a given airplane stalls
in a particular configuration will... - ANS ✓Remain the same regardless of
altitude
In what flight condition must an aircraft be placed in order to spin? - ANS
✓Stalled
During a spin to the left, which wing(s) is/are stalled? - ANS ✓Both wings are
stalled
How will frost on the wings of an airplane affect takeoff performance? - ANS
✓Frost will disrupt the smooth flow of air over the wing, adversely affecting its
lifting capability
Why is frost considered hazardous to flight? - ANS ✓Frost spoils the smooth
flow of air over the wings, thereby decreasing lifting capability
How does frost affect the lifting surfaces of an airplane on takeoff? - ANS
✓Frost my prevent the airplane from becoming airborne at normal takeoff speed
What is ground effect? - ANS ✓The result of inference of the surface of the earth
with the airflow patterns about an airplane
Floating caused by the phenomenon of ground effect will be most realized
during an approach to land when at... - ANS ✓Less than the length of the
wingspan above the surface
What must a pilot be aware of as a result of ground effect? - ANS ✓Induced
drag decreases; therefore, any excess speed at the point of flare may cause
considerable floating

Ground effect is most likely to result in which problem? - ANS ✓Becoming
airborne before reaching recommended takeoff speed
What force makes an airplane turn? - ANS ✓The horizontal component of lift
An airplane said to be inherently stable will... - ANS ✓Require less effort to
control
What determines the longitudinal stability of an airplane? - ANS ✓The
location of the CG with respect to the center of lift
Changes in the center of pressure of a wing affect the aircraft's... - ANS
✓Aerodynamic balance and controllability
An airplane has been loaded in such a manner that the CG is located aft of
the aft CG limit. One undesirable flight characteristic a pilot might
experience with this airplane would be... - ANS ✓Difficulty in recovering from
a stalled condition
What causes an airplane (except a T-tail) to pitch nosedown when power is
reduced and controls are not adjusted? - ANS ✓The downwash on the
elevators from the propeller slipstream is reduced and the elevator effectiveness
is reduced
Loading an airplane to the most aft CG will cause the airplane to be... - ANS
✓Less stable at all speeds
In what flight condition is torque effect the greatest in a single-engine
airplane? - ANS ✓Low airspeed, high power, high angle of attack

The left turning tendency of an airplane caused by P-factor is the result of
the... - ANS ✓Propeller blade descending on the right, producing more thrust
than the ascending blade on the left
When does P-factor cause the airplane to yaw to the left? - ANS ✓When at
high angles of attack
The amount of excess load that can be imposed on the wing of an airplane
depends upon the... - ANS ✓Speed of the airplane
Which basic flight maneuver increases the load factor on an airplane as
compared to straight-and-level flight? - ANS ✓Turns
What is one purpose of wing flaps? - ANS ✓To enable the pilot to make steeper
approaches to a landing without increasing the airspeed
One of the main functions of flaps during approach and landing is to... - ANS
✓Increase the angle of descent without increasing the airspeed
What is the purpose of the rudder on an airplane? - ANS ✓To control yaw
Which is not a primary flight control surface?
A. Flaps
B. Stabilator
C Ailerons - ANS ✓A. Flaps
The elevator controls movement around which axis? - ANS ✓Lateral
Which statement is true concerning primary flight controls?
A. The effectiveness of each control surface increases with speed because
there is more airflow over them.
