answer ✔✔Overbalance
What is the smallest size cable that can be used in flight controls - correct answer ✔✔1/8th"
When MUST a cable be replaced? - correct answer ✔✔When it has 1 broken wire in a critical
fatigue area 40%-50% of wear
3 Types of Cables - correct answer ✔✔1. Non-Flexible
2. Flexible
3. Extra-Flexible
Turnbuckle Installation - correct answer ✔✔NEVER more than 3 threads of rod end showing
outside the Turnbuckle barrel
How do deicer boots work? - correct answer ✔✔rubber "boot" on the L/E inflates to break up
ice
Wing dihedral - correct answer ✔✔Wing angle from the root out

A/C
Wash-in/out - correct answer ✔✔Wash in: Increase AOI, more lift

How far can a fairlead deflect a cable? - correct answer ✔✔No more than 3 degrees
3 modes of pressurization - correct answer ✔✔1. un-pressurized
2. isobaric
3. constant differential
Unpressurized Mode - correct answer ✔✔outflow valve remains open and cabin pressure is
same as ambient pressure
Isobaric Mode - correct answer ✔✔maintained at a specific cabin altitude as flight altitude
changes by opening and closing the outflow valve. (modulates)
constant differential mode - correct answer ✔✔the cabin differential pressure expressed in psi
is the ratio between the internal and external(ambient) air pressure and is a measure of the
