4,600 pounds

If an airplane weighs 4,500 pounds, what approximate wight would the airplane structure be required to support during a 45* banked turn while maintaining altitude

Changes in the center of pressure of a wing affect the aircrafts

Aerodynamic balance and controllability

Which statement relates to Bernoulli's principle

Air traveling faster over The curved paper surface of an airfoil causes lower pressure on the top surface

The term "angle of attack" is defined as the angle...

Between the wing chord line and the relative wind

An airplane has been loaded in such a manner the the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be

Difficultly in recovering from a stalled condition

When are the four forces that act on an airplane in equilibrium

During unaccelerated flight

If an emergency situation requires a downwind landing, pilots should expect a faster

Ground speed at touchdown, a longer ground roll, and the likelihood of overshooting the desired touchdown point

One of the main functions of flaps during approach and landing is to

Increase the angle of descent without increasing the airspeed

What is the relationship of lift, drag, thrust, and weight, when the airplane is in straight and level flight

Lift equals weight and thrust equals drag

The four forces acting on an airplane in flight are

Lift, weight, thrust, and drag

As altitude increases , the indicated airspeed at which a given airplane stalls in a particular configuration will

Remain the same regardless of altitudes

An airplane said to be inherently stable will

Require less effort to control

The amount of excess load that can be imposed on the wing of an airplane depends upon the

Speed of the plane

What causes an airplane (except T-tail) to pitch nose down when power is reduced and controls are not adjusted

The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness reduced

What determines the longitudinal stability of an airplane

The location of the CG with respect to the center of lift

What is the purpose of the rudder on an airplane

To control yaw

What is one purpose of wing flaps

To enable the pilot to make steeper approaches to a landing without increasing the airspeed

Which basic flight maneuver increases the load factor on an airplane as compared to straight and level flight
