Force of Flight
50

Which force allows an aircraft to rise into the air?

Lift

50

This force pulls an aircraft towards the ground due to gravity?

Weight

50

Which force moves an aircraft forward?

Thrust

50

Which force slows an aircraft down?

Drag

50

How many main forces act on an aircraft in flight?

4

100

Lift is mainly produced by what part of the aircraft?

Wings or Airfoil

100

Weight includes the aircraft, fuel, cargo, and what other factor?

Passangers

100

What produces thrust on most aircraft?

Engines or propellers

100

Drag acts in the opposite direction of which force?

Thrust

100

Name all four forces of flight.

Lift, weight, thrust, drag

150

Why does increasing airspeed increase lift?

Faster airflow over the wing increases lift

150

As aircraft weight increases, what must also increase to maintain level flight?

Lift

150

Why is thrust important for producing lift?

It provides airspeed needed for lift

150

Name one factor that increases drag.

Higher speed, poor shape, or extended landing gear

150

Which two forces act vertically on an aircraft?

Lift and weight

200

This factor a long with wing shape, greatly affects how much lift is produced?

Airspeed

200

Name two things that contribute to an aircraft’s weight.

Aircraft structure, fuel, passengers, or cargo

200

If thrust is reduced while drag stays the same, what happens to airspeed?

Airspeed decreases

200

What happens to drag as airspeed increases?

Drag increases

200

Which two forces must be balanced for straight and level flight?

 Lift and weight, thrust and drag

250

For an aircraft to climb, lift must be greater than this force?

Weight

250

Why does an overloaded aircraft need a longer takeoff distance?

More lift is needed to overcome the increased weight

250

An aircraft is flying level and thrust suddenly equals drag. What happens next?

The aircraft continues at the same speed

250

Why do pilots try to reduce drag during flight?

To improve performance and fuel efficiency

250

If lift equals weight and thrust equals drag, what type of flight is occurring?

Straight and level flight
