Q

The point on an aircraft that the Center of Gravity is located is called?

A

17
Q

What acts as the reservoir in a vapor cycle system?

A

The Receiver Dryer

18
Q

What happens to cable tension (rigged) as the temperature decreases?

A

Tension reads lower (decreases).

Cold Wx: Aluminum airframe shrinks more than steel cables, tension will read lower.

Hot Wx: Airframe expands more than cables when hot, so cables will be rigged to a higher tension.

19
Q

Scratch or flute damage is defined as

A

Marks penetrating the surface material but not the complete thickness

20
Q

Stop drill damage is considered what kind of damage?

A

Negligible
