Quiz: Stability
IncorrectQuestion 1
0 / 2.5 pts
In a hover turn, what are the yaw pedals used for?
Vary the collective pitch of the tail rotor blades
Vary the angle of attack of the tail rotor blades
Vary the cyclic pitch of the tail rotor blades
Vary the RPM of the tail rotor blades
Question 2
2.5 / 2.5 pts
Vortex generators mix lower kinetic energy air from outside the boundary
layer with the faster air in the boundary layer and delay separation.
True
False
Question 3
2.5 / 2.5 pts
An increase in wing sweep will have what effect on supersonic flight?
The aircraft can fly faster due to a reduced drag coefficient
The aircraft is limited in speed because of an increased drag coefficient
It places the wing outside of the Mach wave cone of the aircraft
I don't care because I never want to go that fast
Question 4
2.5 / 2.5 pts
A double-wedge airfoil has become commonplace on modern, swept-wing
corporate aircraft, and replaces supercritical airfoils.
True
False
Question 5
2.5 / 2.5 pts
Weight and balance of airplanes is important because
The CG affects the stability and control
If the CG is moved forward the static pitch stability is increased
If the CG is too far forward, the plane may not respond to elevator
commands
All of the above
