27
Q

Loading an airplane to the most aft CG will cause the airplane to be:

A

Less stable at all speeds.

28
Q

The left turning tendency of an airplane caused by P-factor is the result of:

A

Prop blade descending on the right producing more thrust than the ascending blade on the left.

A

VLE.

30
Q

What v-speed stands for maximum landing gear operating?

A

What force makes an airplane turn?

A

The horizontal component of lift.

Q

What does the red line on an airspeed indicator represent?

A

The term “angle of attack” is defined as the angle between:

A

Q

What is an important airspeed limitation that is not color coded on airspeed indicators?

A
