Forces of Flight
Miscellaneous
Stability
Turns
Spins/Stalls
100
This line goes from the leading edge of the wing to the trailing edge.
What is the chord line?
100
This is the is result of the earth' surface altering airflow around an airplane.
What is ground effect?
100
An airplane loaded to its aft (backward) CG limit will be less this.
What is stable?
100

As the angle of bank increases the load factor does this.

What is increase?

100
In order to spin an airplane, this must happen first.
What is a stall?
200
These are the four forces that affect flight.
What are lift, weight, thrust, and drag?
200
The four forces of flight are in equilibrium when the airplane is in this state.
What is straight and level, unaccelerated flight?
200
This is abbreviated CG.
What is center of gravity?
200

Which way should we turn?

Right

200
An aircraft will always stall when this exceeded regardless of speed, attitude, or weight.
What is critical angle of attack?
300
This is the angle formed by the chord line and the relative wind.
What is angle of attack?
300
Ground effect reduces this which may cause floating on landing or getting airborne early.
What is induced drag?
300
When you move the center of gravity too far aft (backward) it will be difficult to recover from this.
What is a stall or a spin?
300
Reference the load factor diagram. An aircraft weighing 4000 lbs. at 75 degrees angle of bank will need to support this weight (approximately).
What is 16,000 lbs?
300
When an airplane enters a spin both wings must be in this condition.
What is stalled?
400
His principle helps explain lift by stating that as the speed of air increases over a curved surface (wing), its pressure gets lower.
Who is Bernoulli?
400
Ground effect happens within this distance from the surface.
What is one wingspan?
400
The relative position between these two things determines longitudinal stability.
What are center of gravity and center of pressure (lift)?
400
Torque most affects an airplane when these three conditions are present.
What are high angle of attack, high power, and low speed?
400
When an airplane enters a spin it will spin in the direction of the wing that has done this.
What is stalled more (or first)?
500
This device allows you to fly at slower airspeeds and steepen landing approaches without stalling.
What are flaps?
500
These are the four basic flight maneuvers.
What are straight and level flight, turns, climbs, and descents.
500
A decrease in downwash over the horizontal stabilizer due to power reduction will cause this.
What is the nose to pitch down?
500
This is another name for asymmetric thrust that turns an airplane to the left.
What is P-factor?
500
As the load factor increases the stall speed will do this.
What is increase?
