What are the three axes an aircraft can rotation freely on?

• Lateral, Vertical and Longitudinal

• Horizontal, Diagonally and straight

• Pitch, roll, yaw

Regardless of which axis is involved, the aircraft will always move around which point?

• Aft CG

• Before CG

• At the CG

Motion at the longitudinal axis is?

• Pitch

• Roll

• Yaw

Which axis is parallel line joining the wing tips?

• Longitudinal

• Lateral

• Vertical

What is control about the vertical axis called?

• Directional control

• Vertical control

• Pitch control

Leading edge flaps and slates are considered to be part of which system in flight controls?

• Primary

• Secondary

• Third

What is the maximum decrease in lift on a wing moving down that flight spoilers can provide?

• 30%

• 80%

• 70%

What is the undesirable effect caused by displacement of ailerons called?

• Aileron Drag

• Turbulence

• Adverse Yaw

The drag near the wing tip pulling the nose of the aircraft around in the direction opposite to the turn is called?

• Alerion Drag

• Turbulence

• Adverse Yaw

What is installed with a stabilator to provide a control similar to what you experience with an elevator?

• Anti servo tab

• Balance arm
