FCOM Flashcards
(41 cards)
- PSEU light, what does it monitor?
TALL
Take off configuration warning
Air/Ground sensing
Landing configuration warning
Landing gear
FCOM 15.20.6
- When do the leading edge slats go from
extend to fully extend?
When the Flap lever is moved beyond the 25 position
FCOM 9.20.17
- What do the flight control switches do?
STBY RUD- activates STANDBY HYDRAULIC system pump and OPENS standby rudder shutoff valve to PRESURISE STANDBY RUDDER POWER CONTROL unit.
FCOM 9.10.1
- What does the Yaw damper switch do
During normal operation the MAIN yaw damper uses SYS B HYD pressure to prevent dutch roll, gust damping and turn cordination.
During manual reversion (loss of system A and B) it engages the standby yaw damper
- What does the FEEL DIFF pressure light indicate? Are there any further considerations?
Either HYD SYSTEM A or
HYD SYSTEM B or
ELEVATOR FEEL PITOT system fails.
DO NOT ATTEMPT AN AUTO LAND
FCOM 9.20.6
- When could the speed trim be activated?
Between 100kts-0.68M
More that 10 seconds after takeoff
More than 5 seconds after releasing the the trim switch
Autopilot not engaged (STS uses AP stab trim controller)
Sensing out of trim
FCOM 9.20.8
- What causes the engine fuel valve closed light to illuminate bright blue?
The valve is in transit or the valve position and the engine start lever disagree
FCOM 12.10.1
- What fuel tank is the fuel temperature
measured from?
A sensor in the No. 1 tank using AC power
FCOM 12.20.3
- What is the max fuel temp?
49 degrees
FCOM 1.10.10
- What causes the fuel FILTER BYPASS light
to illuminate?
An impending fuel filter bypass due to a contaminated filter.
FCOM 12.10.2
- when does the LOW indication illuminate?
When fuel quantity is less than 907kg in the related main tank.
13.When does the fuel CONFIG light illuminate?
If there is more than 726kg in the center tank and the pumps are off.
- When must the wing tanks be full?
Main tanks 1 and 2 must be full if the center tank contains more than 453kgs
- When does the fuel wing IMBAL illuminate?
When main tanks differ by more than 453kgs.
Which bus normally powers the left IRS?
AC STANDBY BUS
Which bus normally powers the right IRS?
AC TRANSFER BUS 2
When will the IRS operate on DC power?
If AC power is not normal, either or both systems automatically switch to backup DC power from the SWITCHED HOT BATTERY BUS
When the IRS is operating on DC power on the ground, will there be any indication outside?
YES, If AC power is removed, the IRS will continue to be supplied by the SWITCHED HOT BATTERY BUS, the ON DC light will illuminate and the ground call warning horn in the nose wheel well will sound.
What causes the ALIGN lights to illuminate, steady? and Flashing?
The ALIGN light will illuminate steady when the alignment process begins, 5-7 min
The FLASHING ALIGN light indicates the position entered doesn’t agree with the last stored position.
What causes the BAT DISCHARGE light to illuminate?
Battery switch on and excessive battery discharge detected.
What causes the TR unit light to illuminate
On the ground…..Any TR unit has failed
In flight…TR 1 or TR 2 and 3 have failed.
(do not use the AFDS mode during an ILS or GLS approach)
What causes the ELEC light to illuminate?
A standby power or DC system fault occurs
Will only operate on the ground.
DO NOT TAKEOFF
What causes the STANDBY PWR OFF light to illuminate?
One or more of the following busses are unpowered
-AC standby bus
-DC standby bus
-Battery bus
What causes the DRIVE light to illuminate?
IDG low oil pressure caused by one of the following:
-IDG failure
-engine shutdown
-IDG automatic disconnect due to high oil temperature
-IDG disconnected through generator drive disconnect switch
