A
Command 10 degrees nose down
4
Q

- Allows the APU fire switch to rotate
10
Q

A
At lift-off
11
Q
If pressure fueling is not available, which tanks can be filled directly using over wing fueling?
A
Both main tanks ON THE 400 ONLY. No overwing fueling on the -800
12

Q
Can the APU power both Generator Busses in flight?
A
Both Transfer busses can be powered on the ground or inflight (-800)
18
Q
What is the Elevator Feel System?
A
The elevator feel system uses the elevator feel computer to provide simulated aerodynamic forces using airspeed (from the elevator pitot system) and stabilizer position. Feel is transmitted to the control columns by the elevator feel and centering unit. To operate the feel system the elevator feel computer uses either hydraulic system A or B pressure, whichever is higher. When either hydraulic system or elevator feel pitot system fail, excessive differential pressure is sensed in the elevator feel computer, and the FEEL DIFF PRESS light illuminates
19
Q
What is Mach Trim?
A
Above Mach .615, the Mach trim system automatically adjusts the elevators with respect to the stabilizer as speed increases. The Mach trim actuator repositions the elevator feel and centering unit, which adjusts the control column neutral position.
