, Aviation Exam Prep 2026: 105 Questions & Answers
SECTION A: PRINCIPLES OF FLIGHT AND PHYSICS
1. Which principle explains the relationship between fluid speed and pressure that is
fundamental to lift generation in aircraft?
A) Archimedes' Principle
B) Newton's Third Law
C) Bernoulli's Principle
D) Pascal's Principle
Answer: C
Explanation: Bernoulli's Principle states that an increase in the speed of a fluid results in a
decrease in pressure. This principle is fundamental to understanding how airfoils generate lift,
as the faster-moving air over the curved upper surface creates lower pressure compared to the
slower-moving air beneath the wing.
2. An object submerged in a fluid experiences an upward force equal to the weight of
the fluid it displaces. This statement defines which principle?
A) Bernoulli's Principle
B) Archimedes' Principle
C) Boyle's Law
D) Charles's Law
Answer: B
Explanation: Archimedes' Principle describes the buoyant force acting on objects in fluids.
This principle is essential for understanding lighter-than-air flight and explains why hot air
balloons and gas balloons rise when the total weight of the aircraft is less than the weight of
the air it displaces.
3. What is the term for the maximum distance between the upper and lower surfaces of
an airfoil?
A) Chord
B) Span
,C) Camber
D) Thickness
Answer: D
Explanation: Thickness is defined as the maximum distance between the upper and lower
wing surfaces, measured perpendicular to the chord line. This measurement is crucial in
determining an airfoil's structural integrity and aerodynamic characteristics.
4. An aircraft wing that has identical upper and lower surface shapes is classified as a:
A) Asymmetrical airfoil
B) Symmetrical airfoil
C) Cambered airfoil
D) Reflex airfoil
Answer: B
Explanation: A symmetrical airfoil features identical upper and lower surfaces, resulting in
no camber. These airfoils are often used in aerobatic aircraft and helicopter rotor blades
because they produce zero lift at zero angle of attack and maintain predictable handling
characteristics throughout various flight attitudes.
5. The straight line connecting the leading edge to the trailing edge of an airfoil is called
the:
A) Camber line
B) Chord line
C) Mean line
D) Pressure line
Answer: B
Explanation: The chord line is an imaginary straight line that connects the leading edge to
the trailing edge of an airfoil. This fundamental reference line is essential for measuring angle
of attack and understanding the aerodynamic properties of the wing.
, SECTION B: FORCES OF FLIGHT
6. Which force acts in opposition to the motion of an aircraft through the air?
A) Lift
B) Thrust
C) Weight
D) Drag
Answer: D
Explanation: Drag is the aerodynamic force that resists an aircraft's forward motion through
the air. It is caused by friction between the air and the aircraft's surfaces, as well as pressure
differences around the aircraft. Drag must be overcome by thrust for the aircraft to maintain
or increase its speed.
7. When all forces acting on an aircraft are balanced and it maintains a constant
altitude and airspeed, the aircraft is in a state of:
A) Acceleration
B) Equilibrium
C) Turbulence
D) Stall
Answer: B
Explanation: Equilibrium occurs when all forces acting on an aircraft are perfectly balanced.
In this state, lift equals weight and thrust equals drag, resulting in unaccelerated flight where
the aircraft maintains a constant velocity and altitude.
8. The force generated by a propeller, jet engine, or rocket that moves an aircraft
forward is called:
A) Lift
B) Drag
C) Thrust
D) Weight
Answer: C
