Private Pilot Ground School Midterm Exam
UPDATED ACTUAL Exam Questions and
CORRECT Answers
What is one purpose of wing flaps? - CORRECT 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 - CORRECT
ANSWER - Increase Angle of descent without increasing the airspeed
What is the purpose of the rudder on an airplane - CORRECT ANSWER - To control yaw
Which is not a primary flight control surface - CORRECT ANSWER - Flaps
The elevator controls movement around which axis - CORRECT ANSWER - Lateral
Which statement is true concerning primary flight controls - CORRECT 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 - CORRECT ANSWER - Flaps allow an
increase in the angle of descent without increasing airspeed.
Which device is a secondary flight control - CORRECT ANSWER - Spoilers
Trim systems are designed to do what? - CORRECT 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 - CORRECT ANSWER - lift weight
thrust and drag
When are the four forces that act on an airplane in equilibrium? - CORRECT ANSWER -
During unaccelerated level flight
What is the relationship of lift drag thrust and weight when the airplane is straight and in level
flight - CORRECT ANSWER - Lift equals weight and thrust equals drag
Which statement relates to bernoulli principle - CORRECT 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 - CORRECT ANSWER - attack
The term angle is defined as the angle between the - CORRECT 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 -
CORRECT ANSWER - attack
The angle of attack at which an airplane wing stalls will - CORRECT 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 - CORRECT ANSWER - remain the same regardless of altitude
In what flight condition must an aircraft be placed in order to spin? - CORRECT
ANSWER - Stalled
During a spin to the left, which wing(s) is/are stalled? - CORRECT ANSWER - Both
wings are stalled
, What is ground effect? - CORRECT 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 - CORRECT ANSWER - less than the length of the wingspan above the
surface
What must a pilot be aware of as a result of ground effect? - CORRECT ANSWER -
Induced drag decreases therefore any excess speed at the point may cause considerable floating
An aircraft leaving ground effect during takeoff will - CORRECT ANSWER - experience
an increase in induced drag and decrease in performance
Ground effect is most likely to result in which problem? - CORRECT ANSWER -
Becoming airborne before reaching recommended takeoff speed
What forces make an airplane turn - CORRECT ANSWER - The horizontal component of
lift.
What determines the longitudinal stability of an airplane - CORRECT ANSWER - The
location of the CG with respect to the center of lift
An airplane said to be inherently stable will - CORRECT ANSWER - require less effort to
control
Changes in the center of pressure of a wing affect the aircraft's - CORRECT ANSWER -
aerodynamic balance and controllability
