Additionals Aeridinamic Flashcards
What is the relationship between induced drag and parasite drag when gross weight is increased?
Induced drag increases more than parasite drag.
What effect , if any, does altitude have on VMC for an airplane with unsupercharged engines?
Decreases with altitude
What is the purpose of the flight spoilers?
Reduce lift without decreasing airspeed.
What affects indicated stall speed?
weight, load factor and power.
Which is the purpose of the wing mounted vortex generators?
Delays the onset of drag divergence at high speeds and aids in maintaining aileron effectiveness at high speed.
When are inboard ailerons normally used?
Low speed and high speed flight
What effect does an increase in airspeed have on a coordinated turn while maintaining a cosntant angle of banck and altitude?
The rate of turn will decrease resulting in no changes in load factor.
By changing the angle of attck of a wing , the pilot can control the airplane’s
lift, airspeed, and drag
What will be the ratio bet ween speed and lift if angle of attack remain constant and speed is doubled?
Lift will be 4 times greather
Subsonic range
Mach below .75
Transonic range
Mach .75 to 1.20
Supersonic range
Mach 1.20 to 5.0
Hypersonic range
Mach above 5.0
What is the purpose of a servo tab?
Reduce control forces by deflecting in the proper direction to move a primary flight control.
If no corrective action is taken by the pilot as angle of bank is increased?
Lift decreases and sink rate increases.
