Types of Airplane Drag

How does Induced Drag vary with Speed?

• It increases with Speed

• It decreases with Speed

• It remains constant

• It doubles

What happens to the Lift of an aircraft once density of the air decreases?

• The Lift force increases

• The Lift force remains constant

• The Lift force decreases

• The Lift forces doubles

Drag depends on several factor:

• Dynamic Pressure, Drag force, velocity

• Velocity, air density

• Drag coefficient, Lift force, velocity

• Dynamic Pressure, Drag Coefficient, Wing Surface

What is the minimum drag speed?

• Best Glide Speed

• The maximum speed of an aircraft

• The minimum speed of an aircraft

• The speed, a Pilot may retract Flaps
