Question 1

Aileron travel

Answer 1

25 up 17 down

Question 2

Elevator travel

Answer 2

20 up

14 down

Question 3

Rudder Boost operation:

Answer 3

Two pneumatic boost servos in the rudder cable system provide force for rudder boosting.
Differential pressure switch (Delta P) senses bleed-air press from each engine. If press diff exists (60 psi), a circuit is completed, which opens a solenoid valve that directs regulated bleed-air pressure to the rudder boost servo.

Reads 60 psi differential as an engine failure.

Question 4

Rudder Boost On/Off Switch

Answer 4

When L/R Bleed Air switches in Open or Envir Off, rudder boost armed when positioned On. If Bleed Air switches in inst and envir off, system will not arm.

Question 5

What powers the rudder boost system?

Answer 5

2 DFB

Question 6

Split flap protection

Answer 6

If either flap splits 3-6 degrees during travel, the cam/switch interrupts the circuit and stops the motor. Flaps cannot be moved until failure is corrected.

Question 7

What powers the flaps?

Answer 7

3 DFB

Flap CB

• Motor
• Control

Question 8

Max altitude with yaw damp inoperative?

Answer 8

17,000’

With Raisbeck DABS, yaw damp system can be MEL’d

Question 9

What type of flaps are on the King Air?

Answer 9

Fowler Flaps

Question 10

What powers the pitch trim?
