What creates wingtip vortices?
High-speed airflow over the wing
Difference in pressure between the top and bottom of the wing
The shape of the fuselage
Low-speed airflow under the wing
How does the angle of attack affect induced drag?
Higher angles of attack increase induced drag
Angle of attack has no effect on induced drag
Higher angles of attack decrease induced drag

Reduces induced drag
What is 'washout' in aircraft design?
A twist in the wing to reduce induced drag
A method to clean the aircraft
A landing gear configuration
A type of engine cooling system
What happens to induced drag at low airspeeds?
Induced drag is lower
Induced drag remains constant
Induced drag is negligible
Induced drag is higher
What is the 'total drag' on an aircraft?
The difference between parasite and induced drag
