SOP FCOM Flashcards
altitude that is 4 000 ft below the optimum produces a significant penalty (approximately 5 % of fuel). Flight 8 000 ft below the optimum altitude produces a penalty of
more than 10 % against trip fuel. (The usual contingency allowance is 5 %).
Do not pressurize the green hydraulic system without clearance from ground personnel, if any gear door is open. Remember that the green hydraulic system is pressurized if;
the yellow system is pressurized and the PTU is on AUTO.
If the aircraft has not been electrically supplied for 6 h or more, perform the following check: BAT 1 pb and BAT 2 pb CHECK OFF
BAT 1 and BAT 2 pb CHECK ABOVE
25.5 V Battery voltage above 25.5 V ensures a charge above 50 %.
If the aircraft has not been electrically supplied for 6 h or more
If the battery voltage is at or below 25.5 V: A charging cycle of about
20 min is required. BAT 1 pb and BAT 2 pb…..AUTO EXT PWR pb-sw…..ON Check on ELEC SD page, that the battery contactor is closed and the batteries are charging. After 20 min: BAT 1 + 2 pb….OFF BAT 1 and 2 VOLTAGE..CHECK ABOVE 25.5 V BAT 1 + 2 pb…..AUTO
If the battery voltage is above 25.5 V: BAT 1 pb and BAT 2 pb….AUTO If the APU is started on batteries only, it should be started within
30 min after the selection of batteries to AUTO (35 min after battery selection to AUTO, the battery charge is less than 25 % of maximum capacity).
If the aircraft has been electrically supplied during the last 6 h: BAT 1 pb and BAT 2 pb….

At electrical power-up, the FMGSs and FCU run through various internal tests. Allow enough time
(3 min) for tests’ completion, and do not start to press pushbuttons until the tests are over
If there is a transfer of duties during this flight, the flight crew must remind the incoming flight crew of the
applicable OEB(s) during the briefing that is done when transferring the duties.
The volume of the hydraulic fluid in the reservoirs may change with Outside Air Temperature. As a result, the reservoir fluid level that appears on the HYD SD page may be outside of the normal range with
no HYD RSVR LO AIR PR or HYD RSVR LO LVL warning. If the fluid level is outside of the normal range, contact maintenance to determine if service is required.
Check that the oil quantity is at or above 8.9 qt + estimated consumption (maximum estimated consumption.
~ 0.45 qt/h) and not below 10.6 qt
ENG OIL QUANTITY
If the engines have been shut down for more than 60 min, decrease the above quantities by
3 qt to take into account the oil thermal expansion.
If the engine oil quantity indication does not appear on the ENG SD page, set the
ENG 1 and 2 FADEC GND PWR pb-sw on the overhead maintenance panel to ON. After the check of the engine oil quantity, set the ENG 1 and 2 FADEC GND PWR pb-sw to off.
FLT controls check
If flight control surface positions do not agree with the control handle positions, check with the maintenance crew before
applying hydraulic power.
The ACCU PRESS indication must be in the green band. If required use the
electric pump on yellow hydraulic system to recharge the brake accumulator.

When one brake temperature is above
500 °C, avoid applying the parking brake, unless operationally necessary.

A fast IRS alignment must be performed if a complete IRS alignment is not necessary and the difference between the IRS position and the FMGC position is at or above
5 NM (see MCDU POSITION MONITOR page).
complete IRS alignment must be performed in the following cases:
‐ Before the first flight of the day, or ‐ When there is a crew change, or ‐ When the GPS is not available and the NAVAIDS coverage is poor on the expected route, or ‐ When the GPS is not available and the expected flight time is more than 3 h.
Leaving the EXIT selector or NO SMOKING selector or NO PORTABLE/ELEC DEVICE selector ON prevents the
emergency batteries from charging. If the CIDS has been programmed (option) for a non-smoking flight, NO SMOKING or NO PORTABLE/ELEC DEVICE signs are permanently on, with the EXIT sw or NO SMOKING sw or NO PORTABLE/ELEC DEVICE sw at AUTO (with permanent charge of emergency batteries).
PACK FLOW selector…AS RQRD
Select: LO : If the number of occupants is below
141/168 (A321)
If the charge of at least one battery is not below 60 A:
Wait until the end of the charging cycle of the batteries and perform this check again
