Question 1

What does Newton's Third Law of Motion state?

Accepted Answer

For every action, there is an equal and opposite reaction.

Answer

The force acting on an object is equal to its mass times acceleration.

Answer

A body in motion stays in motion unless acted upon by an external force.

Answer

A body at rest stays at rest unless acted upon by an external force.

Question 2

Which of the following describes equilibrium in flight?

Accepted Answer

The aircraft is in straight flight at constant airspeed.

Answer

The aircraft is accelerating upward.

Answer

The aircraft is turning at constant height and airspeed.

Answer

The aircraft is descending rapidly.

Question 3

How is lift generated by an aerofoil?

Accepted Answer

By the pressure differential between the upper and lower surfaces of the wing.

Answer

By reducing drag to zero.

Answer

By increasing the angle of incidence.

Answer

By increasing the weight of the aircraft.

Question 4

What does Bernoulli's theorem state?

Accepted Answer

As the velocity of air increases, its pressure decreases.

Answer

Air pressure increases with altitude.

Answer

Air pressure remains constant regardless of velocity.

Answer

As the velocity of air decreases, its pressure increases.

Question 5

Which of the following is NOT one of the four main forces acting on an aircraft?

Weight

Question 6

What happens when lift equals weight during flight?

Accepted Answer

The aircraft maintains level flight.

Answer

The aircraft stalls.

Answer

The aircraft climbs.

Answer

The aircraft descends.

Question 7

What is the angle of attack?

Accepted Answer

The angle between the wing chord and relative airflow.

Answer

The angle between the tail plane and the horizon.

Answer

The fixed angle between the wing chord and the aircraft's longitudinal axis.

Answer

The angle between the propeller and the fuselage.

Question 8

What happens if the angle of attack exceeds the stalling angle?

Accepted Answer

The aircraft stalls.

Answer

The aircraft descends smoothly.

Answer

The aircraft climbs rapidly.

Answer

The aircraft accelerates.

Question 9

What is induced drag?

Accepted Answer

Drag caused by wingtip vortices and downwash

Answer

Drag caused by interference between aircraft parts

Answer

Drag caused by air clinging to the aircraft's surface
