What is one purpose of wing flaps?
To enable the pilot to make steeper approaches to a landing without increasing the airspeed
What is the purpose of the rudder on an airplane?
To control yaw.
The four forces acting on an airplane in flight are…
lift, weight, thrust, and drag.
When are the four forces that act on an airplane in equilibrium?
During unaccelerated level flight.
The angle between the chord line of an airfoil and the relative wind is known as the angle of
Attack
What is ground effect?
The result of the interference of the surface of the Earth with the airflow patterns about
What force makes an airplane turn?
The horizontal component of lift
An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be
difliculty in recovering from a stalled condition.
The left turning tendency of an airplane caused by P-factor is the result of the
propeller blade descending on the right, producing more thrust than the ascending blade on the left.
Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flighr?
Turns
Density altitude
Reduces power because the engine is taking in less air
Bernoulies principle
High pressure below the wing/low pressure above the wing
Induced drag
Is associated with lift
It slows the aircraft movement
Bernoulies principle
High pressure below the wing/low pressure above the wing
Wake Turbulence
When the plane is heavy, clean and slow

What are the two components of a turn

When will a wing stall
B. Exceeding the critical angle of attack
