AVIA 305: AIRCRAFT
PERFORMANCE
An airplane flying at CL(max) will have - ANSWERS-more induced
drag than parasite drag.
Induced drag is - ANSWERS-more important to low aspect ratio
airplanes than to high aspect ratio airplanes.
reduced when the airplane enters ground effect.
reduced if the airplane has winglets.
Induced drag results from the lift vector being tilted to the rear, because
- ANSWERS-the tip vortices cause downwash behind the wing.
the relative wind behind the wing is pushed downward.
the local relative wind at the AC is depressed.

PERFORMANCE
An airplane with a heavy load _____ it can when lightly loaded -
ANSWERS-can glide the same distance as
If an airplane has a symmetrical wing that has an angle of incidence of
0° during takeoff, all the drag is - ANSWERS-parasite drag.
A low‐tailed airplane with static ports beneath the wing leaves ground
effect after takeoff. It will have: - ANSWERS-increased drag, nose‐up
pitch, higher IAS
The equation Ta = Q(V2 - V1) shows that - ANSWERS-you can get
more thrust from a jet engine by using water injection.
you can get more thrust from a jet engine by decreasing the exhaust pipe
area.
Q in Ta = Q(V2 - V1) is the mass flow (slugs/sec). The mass flow
depends on - ANSWERS-the cross‐sectional area of the turbojet engine
inlet.

the engine inlet velocity.
the density of the air at the same point.
The equation Np = 2V1 / (V2 + V1) shows that decreasing the exhaust
pipe area will - ANSWERS-decrease the propulsive efficiency of a jet
engine.
