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

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.

  • Antiskid and autobrakes operational
  • AUTO BRAKE select switch positioned to RTO
  • Wheel speed less than 60 knots

79
Q

What is the function of the power transfer unit?

A

The power transfer unit supplies the additional volume of hydraulic fluid needed to operate the auto-slats and leading edge flaps and slats at the normal rate when the system B engine-driven hydraulic pump volume is lost. The PTU uses system A pressure to power a hydraulic motor- driven pump, which pressurizes system B hydraulic fluid.

80
Q

With external ground power connected, and the battery switch in the OFF position, can the main deck cargo door be positioned using the electrical pump?

A

No, the battery switch must be in the auto or on position to provide electric power. The door is opened using system A hydraulic pressure from the aircraft electric motor pump or a hydraulic ground cart.

81
Q

Could the door accidentally be operated in flight using the hydroelectric pump?

A

No. The door is electrically un-powered in flight. (Could not find in the -800)

82
Q

If one EEC fails can we use the operable EEC?

A

No it must be put in the hard alternate mode

83
Q

What is the function of the Equipment Cooling System?

89
Q

Are the fuel valves and crossfeed valve AC or DC powered?

A

DC

90
Q

If AC power is lost, where do the IRSs get their electrical power?

A

The switched hot battery bus.

91
Q

Will the Speed Trim system still operate with a single channel failure?

A

Yes

92
Q

With only one pack operating, and the switch in auto, what will happen?

A

The pack will regulate to high flow.

93
Q

When is approach idle selected?

A

When the flaps are in the landing configuration or either engine anti ice switch is ON

94
Q

With the landing gear up and the flaps set to 15 degrees, can you silence the landing gear warning horn?

A

No. Because flaps 15 is a landing flap setting.

95
Q

In alternate breaking on the -400 what protections do we lose? Do we lose them on the -800?

A

We lose locked wheel, and touchdown protection in alternate breaking.

** On the -800 we have them in both normal and alternate **

96
Q

When does the Landing Gear Transfer Unit operate?

A

When all of the following conditions exist:

  • airborne
  • number 1 engine RPM drops below a limit value
  • LANDING GEAR lever is positioned up

A

No

100
Q

How many volts is the battery?

A

24 Volts

101
Q

What are the conditions for speed trim operation?

A
  • Airspeed 100 – .6 mach
  • 10 seconds after takeoff
  • 5 seconds following release of trim switches
  • Autopilot not engaged
  • Sensing of a trim requirement
102
Q

What does the PSEU system monitor?

A

Takeoff Configuration Warnings
Landing Configuration Warnings
Landing Gear
Air/Ground Sensing

103
Q

What happens when the FLT CONTROL switch is moved to STBY RUD?

A
  • Activates the standby electric motor-driven pump
  • Shuts off the related hydraulic system pressure to ailerons, elevators and rudder by closing the flight control shutoff valve
  • Opens the standby rudder shutoff valve
  • Deactivates the related flight control LOW PRESSURE light when the standby rudder shutoff valve opens
  • Allows the standby system to power the rudder and thrust reversers
  • Illuminates the STBY RUD ON, Master Caution, and Flight Controls (FLT CONT) lights.
104
Q

What happens between 60 and 90 knots if a takeoff is rejected?

A

The autobrake disarm light illuminates and autobraking is NOT initiated.

105
Q

If the COWL VALVE OPEN light remains illuminated bright blue with the engines at idle, what can be done to correct the issue?

A

Increase engine thrust slightly (minimum of 30%)

106
Q

What is the autoslat system?

A

With flaps selected to 1, 2, and 5, autoslats will automatically drive the slats to the fully extended position if the aircraft approaches a stall

107
Q

If the APU is running and the battery switch is moved to the OFF position, will the APU shutdown?

A

Yes, because of power loss to the electronic control unit

177
Q

With the STANDBY POWER switch in the AUTO position, and the loss of all AC generators, what will happen upon touchdown?

A

Air ground logic will prevent the battery from continuing to power the AC and DC standby busses. As a result, all equipment powered by the AC and DC standby busses is lost until the STANDBY POWER switch is moved to the BAT position. (COULD NOT FIND IN -800 FCOM)
