General Operating Procedures Flashcards
AC power vs APU Power. Which one to use?
AC power until 10mins push back. Unless required for comfort
How long you can left a powered aircraft unattended?
Not more than five minutes.
EsTABLISHING EXTERNAL AC POWER - UNPOWERED AIRPLANE?
BATTERY MASTER–ON
Check: AC switch/light AVAIL illuminated
AC SELECT / IN USE
ECP Check: ED-2: TRU, voltage and load indications are normal
AC POWER SOURCE - TRANSFER FROM EXTERNAL TO APU
APU: START
AC-DESELECT / AVAIL: check: AC switch/light AVAIL illuminated
Explain the ANTI-SKID 1 CHANNEL INOPERATIVE CALCULATIONS
Check the remarks section
Calculate V1 using the performance cards and compare to the MAX V1 calculated from the takeoff report.
Use the lower of the two for the actual V1.
How long should you wait before establishing APU bleed air?
two minutes
Explain CRJ 200 bleeds open takeoff, do you shout down the engine?
Yes APU is shut down after the second engine start, unless needed for passenger comfort.
CRJ 200: Engine bleeds shall be ______for all FFOD takeoffs.
closed
The APU is not started after landing unless:
- less 30 mins turn
- Environmental conditions require
- External AC power is unavailable at the gate
Need for APU in flight may include:
- Passenger comfort
- CRJ 200: Missed approach performance with wing/cowl anti-ice on
- Abnormal or emergency procedures
CRJ 200 APU START - GROUND
1) APU GEN: OFF
2) Check: 10th STAGE APU LCV–10th STAGE ISOL- APU POWER / FUEL——– DESELECT / EXTINGUISH
3) APU PWR FUEL: SELECT / EXTINGUISH
4) Check: APU SOV OPEN- APU IN BITE status message (5-6 seconds)- APU gauge indications displayed- APU DOOR OPEN indication
5) APU START / STOP: SELECT / START
6) Check: APU START status message illuminated (around 50% RPM)
7) Check: 50% RPM, START extinguished—95% RPM, AVAIL illuminated
8) APU GEN—ON
9) Check: Voltage, frequency and load indications– TRU, voltage and load
APU PWR / FUEL must be _______ between each APU start.
