PRIVATE PILOT GROUND
SCHOOL MIDTERM EXAM 2025
QUESTIONS AND ANSWERS
What is one purpose of wing flaps? - ....ANSWER ...-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 -
....ANSWER ...-Increase Angle of descent without increasing the airspeed
What is the purpose of the rudder on an airplane - ....ANSWER ...-To control yaw
Which is not a primary flight control surface - ....ANSWER ...-Flaps
The elevator controls movement around which axis - ....ANSWER ...-Lateral
Which statement is true concerning primary flight controls - ....ANSWER ...-The
effectiveness of each control surface increases with speed because there is more airflow
over them
Which of the following is true concerning flaps - ....ANSWER ...-Flaps allow an
increase in the angle of descent without increasing airspeed.
Which device is a secondary flight control - ....ANSWER ...-Spoilers

,Trim systems are designed to do what? - ....ANSWER ...-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 - ....ANSWER ...-lift weight
thrust and drag
When are the four forces that act on an airplane in equilibrium? - ....ANSWER ...-
During unaccelerated level flight
What is the relationship of lift drag thrust and weight when the airplane is straight and in
level flight - ....ANSWER ...-Lift equals weight and thrust equals drag
Which statement relates to bernoulli principle - ....ANSWER ...-Air traveling faster
over curved surface of an airfoil causes lower pressure on the top surface
The Acute angle A is the angle of - ....ANSWER ...-attack
The term angle is defined as the angle between the - ....ANSWER ...-chord line of
the wing and the relative wind
The angle between the chord line of the airfoil and relative wind is known as the angle of
- ....ANSWER ...-attack
The angle of attack at which an airplane wing stalls will - ....ANSWER ...-remain
the same regardless of gross weight
As altitude increases, the indicated airspeed at which a given airplane stalls in a
particular configuration will - ....ANSWER ...-remain the same regardless of
altitude

, In what flight condition must an aircraft be placed in order to spin? -
....ANSWER ...-Stalled
During a spin to the left, which wing(s) is/are stalled? - ....ANSWER ...-Both
wings are stalled
What is ground effect? - ....ANSWER ...-The result of the interference 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 - ....ANSWER ...-less than the length of the wingspan
above the surface
What must a pilot be aware of as a result of ground effect? - ....ANSWER ...-
Induced drag decreases therefore any excess speed at the point may cause considerable
floating
An aircraft leaving ground effect during takeoff will - ....ANSWER ...-experience an
increase in induced drag and decrease in performance
Ground effect is most likely to result in which problem? - ....ANSWER ...-
Becoming airborne before reaching recommended takeoff speed
What forces make an airplane turn - ....ANSWER ...-The horizontal component of
lift.
What determines the longitudinal stability of an airplane - ....ANSWER ...-The
location of the CG with respect to the center of lift
