, Aviation Exam Prep 2026/2027: 90 Questions & Answers
SECTION A: MULTIPLE CHOICE QUESTIONS
Instructions: Select the best answer from the options provided. Each question carries one
mark.
Topic 1: Aerodynamics and Flight Principles
1. Which term describes the science that deals with the forces of air in motion?
A. Aeronautics
B. Aerodynamics
C. Aviation
D. Aerospace
Answer: B
Explanation: Aerodynamics is specifically the branch of physics that studies the forces
exerted by air in motion and the interaction between moving air and solid bodies, such as
aircraft wings.
2. What is the approximate composition of Earth's atmosphere?
A. 70% nitrogen, 29% oxygen, 1% other gases
B. 78% nitrogen, 21% oxygen, 1% other gases
C. 65% nitrogen, 34% oxygen, 1% other gases
D. 80% nitrogen, 19% oxygen, 1% other gases
Answer: B
Explanation: The atmosphere consists primarily of nitrogen (78%) and oxygen (21%), with
the remaining 1% composed of argon, carbon dioxide, and trace gases. This composition is
critical for understanding atmospheric properties and their effects on flight.
3. According to Daniel Bernoulli's principle, what happens to fluid pressure when its velocity
increases?
A. Pressure remains constant
B. Pressure increases
C. Pressure decreases
D. Pressure becomes zero
Answer: C
Explanation: Bernoulli's principle states that as the velocity of a fluid increases, the pressure
,exerted by that fluid decreases. This principle is fundamental to understanding how aircraft
wings generate lift.
4. Which force opposes the forward movement of an aircraft in flight?
A. Lift
B. Thrust
C. Drag
D. Gravity
Answer: C
Explanation: Drag is the aerodynamic resistance force that acts opposite to the aircraft's
direction of motion. It is a natural force that must be overcome by thrust for forward flight.
5. The upward force that opposes gravity and supports the weight of an aircraft is called:
A. Thrust
B. Lift
C. Drag
D. Buoyancy
Answer: B
Explanation: Lift is the aerodynamic force perpendicular to the relative wind that
counteracts the weight of the aircraft. It is generated primarily by the wing's airfoil shape and
angle of attack.
6. Which axis of rotation passes from the nose of an aircraft through the tail?
A. Vertical axis
B. Lateral axis
C. Longitudinal axis
D. Horizontal axis
Answer: C
Explanation: The longitudinal axis runs from the nose to the tail of the aircraft. Rotation
around this axis is called roll, which is controlled by the ailerons.
7. Movement of an aircraft around the lateral axis is known as:
A. Roll
B. Yaw
C. Pitch
D. Drift
, Answer: C
Explanation: The lateral axis extends from wingtip to wingtip, and rotation around this axis
produces pitching motion. This is controlled by the elevator or stabilator.
8. The surface on an aircraft that controls yaw is the:
A. Aileron
B. Elevator
C. Flap
D. Rudder
Answer: D
Explanation: The rudder is the control surface located on the vertical stabilizer. When
deflected, it generates a sideways force that rotates the aircraft around its vertical axis,
creating yaw.
9. What is the name for the component of an aircraft specifically designed to produce lift,
thrust, or directional stability?
A. Fuselage
B. Airfoil
C. Empennage
D. Landing gear
Answer: B
Explanation: An airfoil is any structural component whose shape is specifically designed to
produce a desired aerodynamic force. Wings, propeller blades, and control surfaces all
function as airfoils.
10. The curved upper surface of an airfoil from the leading edge to the trailing edge is called
the:
A. Chord
B. Camber
C. Crown
D. Flange
Answer: B
Explanation: Camber refers to the curvature of an airfoil's surfaces. The upper camber is
curved to create a longer path for air to travel over the wing, generating lift through
Bernoulli's principle.
