AFCAT Aviation & Aeronautics

Question 1

According to Bernoulli's principle, what creates lift on an aircraft wing?

Accepted Answer

Lower air pressure above the wing and higher pressure below

Answer

Higher air pressure above the wing than below

Answer

Equal pressure on both surfaces of the wing

Answer

Engine thrust pushing the aircraft upward

Question 2

What does the term 'angle of attack' refer to in aviation?

Accepted Answer

The angle between the wing chord line and the relative airflow

Answer

The angle between the aircraft's nose and the horizon

Answer

The angle at which a pilot approaches a target

Answer

The pitch angle during takeoff rotation

Question 3

In aviation, what is a 'stall'?

Accepted Answer

When the aircraft exceeds its critical angle of attack and loses lift

Answer

When an aircraft's engine stops working mid-flight

Answer

When the landing gear fails to deploy on approach

Answer

When the aircraft runs out of fuel at altitude

Question 4

What does Mach 1 represent?

Accepted Answer

The speed of sound

Answer

An airspeed of exactly 1,000 km/h

Answer

Twice the aircraft's normal cruising speed

Answer

One-tenth the speed of light

Question 5

What are ailerons primarily used for on an aircraft?

Accepted Answer

Controlling roll (banking left and right)

Answer

Controlling pitch (nose up and down movement)

Answer

Controlling yaw (nose left and right rotation)

Answer

Increasing engine thrust during takeoff

Question 6

What is the primary purpose of flaps during takeoff and landing?

Accepted Answer

To increase lift at lower airspeeds by increasing wing camber and area

Answer

To increase the aircraft's maximum airspeed

Answer

To control the aircraft's directional stability

Answer

To reduce the wingspan and improve aerodynamics

Question 7

What does IFR stand for in aviation?

Accepted Answer

Instrument Flight Rules

Answer

Internal Flight Regulations

Answer

Integrated Flight Response

Answer

International Flying Requirements
