What is the primary function of an aircraft's wings?

  1. To provide lift

  2. To provide stability

  3. To provide control

  4. To provide propulsion


Correct Option: A
Explanation:

The wings of an aircraft are designed to generate lift, which is the force that opposes gravity and allows the aircraft to fly.

What is the term for the curved shape of an aircraft's wing?

  1. Camber

  2. Dihedral

  3. Sweep

  4. Aspect ratio


Correct Option: A
Explanation:

Camber is the curved shape of an aircraft's wing, which helps to generate lift.

What is the primary function of an aircraft's fuselage?

  1. To house the passengers and crew

  2. To provide structural support

  3. To generate lift

  4. To provide control


Correct Option: A
Explanation:

The fuselage of an aircraft is the main body of the aircraft, which houses the passengers and crew.

What is the term for the horizontal tail surface of an aircraft?

  1. Elevator

  2. Rudder

  3. Aileron

  4. Horizontal stabilizer


Correct Option: D
Explanation:

The horizontal stabilizer is the horizontal tail surface of an aircraft, which helps to provide stability and control.

What is the primary function of an aircraft's engine?

  1. To generate thrust

  2. To provide lift

  3. To provide stability

  4. To provide control


Correct Option: A
Explanation:

The engine of an aircraft is responsible for generating thrust, which is the force that propels the aircraft forward.

What is the term for the angle at which an aircraft's wing is swept back?

  1. Camber

  2. Dihedral

  3. Sweep

  4. Aspect ratio


Correct Option: C
Explanation:

Sweep is the angle at which an aircraft's wing is swept back.

What is the primary function of an aircraft's ailerons?

  1. To provide roll control

  2. To provide pitch control

  3. To provide yaw control

  4. To provide thrust


Correct Option: A
Explanation:

Ailerons are the primary flight control surfaces that provide roll control for an aircraft.

What is the term for the ratio of an aircraft's wingspan to its wing chord?

  1. Camber

  2. Dihedral

  3. Sweep

  4. Aspect ratio


Correct Option: D
Explanation:

Aspect ratio is the ratio of an aircraft's wingspan to its wing chord.

What is the primary function of an aircraft's rudder?

  1. To provide roll control

  2. To provide pitch control

  3. To provide yaw control

  4. To provide thrust


Correct Option: C
Explanation:

The rudder is the primary flight control surface that provides yaw control for an aircraft.

What is the term for the angle at which an aircraft's wing is tilted upward?

  1. Camber

  2. Dihedral

  3. Sweep

  4. Aspect ratio


Correct Option: B
Explanation:

Dihedral is the angle at which an aircraft's wing is tilted upward.

What is the primary function of an aircraft's elevator?

  1. To provide roll control

  2. To provide pitch control

  3. To provide yaw control

  4. To provide thrust


Correct Option: B
Explanation:

The elevator is the primary flight control surface that provides pitch control for an aircraft.

What is the term for the ratio of an aircraft's lift to its drag?

  1. Lift-to-drag ratio

  2. Thrust-to-weight ratio

  3. Power-to-weight ratio

  4. Glide ratio


Correct Option: A
Explanation:

Lift-to-drag ratio is the ratio of an aircraft's lift to its drag.

What is the primary function of an aircraft's flaps?

  1. To increase lift

  2. To increase drag

  3. To provide roll control

  4. To provide pitch control


Correct Option: A
Explanation:

Flaps are used to increase lift, typically during takeoff and landing.

What is the term for the angle at which an aircraft's propeller is tilted upward?

  1. Camber

  2. Dihedral

  3. Sweep

  4. Propeller pitch


Correct Option: D
Explanation:

Propeller pitch is the angle at which an aircraft's propeller is tilted upward.

What is the primary function of an aircraft's slats?

  1. To increase lift

  2. To increase drag

  3. To provide roll control

  4. To provide pitch control


Correct Option: A
Explanation:

Slats are used to increase lift, typically during takeoff and landing.
