APU
The APU is guaranteed to start at or below what altitude?
39,000’
APU
Will the APU shut down automatically upon detection of a fire?
Yes. During ground and in flight operations if the APU fire detection circuit detects a fire except during use of the test switch
APU
After an APU start when will the APU load control valve allow APU for engine start and pack operation?
The load control valve will not open on the ground for 60 seconds. This function is removed in flight.
APU
Fuel is supplied to the APU from where?
The left wing fuel hopper using the left main fuel pump. (May use the right main rank and pump if cross flow valve is open)
Electrical
How many ground service bus switches are there and where are they located?
Three
- forward external switch panel
- tail compartment electrical power control panel
- system monitor test panel
Electrical
When will the main battery switches in the overhead panel illuminate on?
The main batteries are powering the ESS DC buses:
- starting the APU
- AUX hydraulic pump is operating
- when Batts are powering essential DC bus(s)
Electrical
How many E batts are there?
4 total. ( 2 avionics and 2 lighting)
Electrical
When emergency power system is armed, when will the e batts activate?
Any time either L or R ESS Bus power drops below 20v
Poweplant
Pulling the Engine Fire Handle will shut off what items on the associated side?
Fuel
Hydraulics
Electrics
Powerplant
What is the starter duty cycle?
Three starts with a maximum of three minutes per cycle
Delay 15 seconds between start cycles
After three start cycles, delay use of the starter for at least 15 minutes.
Powerplant
What is the preferred Engine Airstart procedure?
Automatic
Hydraulics
What items are lost if you love e R Hydraulic System Pressure?
R Thrust Reverser
Redundant Hydraulics to the flight controls.
Hydraulics
The PTU is driven by the right hydraulic pressure and USES left hydraulic system fluid. When armed, what will cause it to turn on automatically?
The PTU will turn on automatically if L hydraulic system pressure drops below 1500 psi.
Hydraulics
What conditions will prevent automatic PTU operation when the PTU is armed?
- HYD system quantity below 1.5 gallons
- R HYD system fluid 104 C or greater.
Hydraulics
When armed, what will cause the AUX HYD pump to turn on automatically?
Brake pedals depressed > 10 degrees with no other source of power to the brakes.
Hydraulics
The AUX HYD pump is capable of powering what items?
Nose wheel steering Main entrance door Flaps Brakes Standby Rudder (YD 1)
Flight Controls
In the event of a Aileron Hardover Protection System (HOPS) activation, HYD power is shut off to what surfaces?
An Aileron HOPSwill deactivate hydraulics to BOTH aileron actuators even if only one actuator sensed a Hardover. The spoiler actuators will still have power.
LG and Brakes
What is Emergency Landing Gear Nitrogen Blowdown bottle pressure?
3100 PSI
LG and Brakes
What is the tire speed limit?
195 knots ground speed
LG and Brakes
Anti skid braking is available from which hydraulic systems?
L HYD system
PTU
AUX HYD system
Pneumatics
What is the maximum permitted cabin pressure altitude differential in flight?
10.48 psi
Pneumatics
What is the maximum cabin pressure differential for taxi, takeoff or landing?
0.3 PSI
Pneumatics
What cabin altitude will cause the passenger oxygen masks to deploy?
14,750 +/-250
