Vol 1
What controls air into the AC pack?
Pack valve
Vol 2 16-37
Heavy pressure damage is called
Compression

Vol 1
The point on an aircraft that the Center of Gravity is located is called?
The ARM
What acts as the reservoir in a vapor cycle system?
The Receiver Dryer
What happens to cable tension (rigged) as the temperature decreases?
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.
Scratch or flute damage is defined as
Marks penetrating the surface material but not the complete thickness
Stop drill damage is considered what kind of damage?
Negligible

Creeps or Bows
How are bolts measured?
8ths and 16ths
What is the recommended bend radius for aircraft fire detection systems?
3in
What happens when the boiling point rises to gas?
Pressure decrease, boiling point decreases
When you have a high volume of gas what happens?
Volume increases, pressure decreases
