FCOM Autoflight performance
What is the minimum number of cabin crew?
3 crew on A319 with max 150 pax.
4 in all other cases unless in unforeseen circumstances and with duty pilot authorisation (with restrictions).
OPS A 4.1.4
What is the wind limitation for use of passenger and cargo doors?
The maximum wind for passenger door operation is 65 kt.
The maximum wind for FWD and AFT cargo door operation is 40 kt (or 50 kt, if the aircraft nose is into the wind, or if the FWD and AFT cargo doors are on the leeward side).
The FWD and AFT cargo doors must be closed before the wind speed exceeds 65 kt.
FCOM LIMITATIONS
What are the speed limits and maximum tiller deflection for –
1 deflated tire
2 deflated tires
Damaged tires
1 tyre (one or more gears), 7kts in turn 2 tyres on one gear, 3 kts in turn, maximum 30 degrees
If tyres are damaged then an inspection must be carried out.
Limitations - L/G
What is the maximum brake temperature for take off?
300 degrees (brake fans off) Limitations L/G
During taxi out, if an arc indication appears above the brake temperature on the ECAM WHEEL page set the brake fans on.
The maximum certified brake temperature prior to take-off is 300°C. In circumstances when brake temperatures approach this limitation, the recommended procedure is to use brake fans to reduce the temperature to 150°C.
OMB
Where would you find the minimum flight crew oxygen requirement?
FCOM Limitations oxygen
Starter cycle limitations for the APU?
APU STARTER
After 3 starter motor duty cycles, wait 60 min before attempting 3 more cycles.
Starter cycle limitations for the Engines?
4 consecutive cycles: Each lasts a maximum of 2 min
Pause between start attempts: 20 s
Cooling period, after 4 start attempts: 15 min
No running engagement of the starter, when N2 is above 20 %.
What is IRS drift? Where do you find the tolerences?
When do you do a quick align/full alignment of the IRS’s? When do you consider the IRS to unserviceable?
After the flight, the flight crew must check the IRS performance once parked. To check IRS performance, the flight crew compares the IRS position with the FMGC position in Nautical Miles.
The NAV TIME is the cumulated block time since the latest IRS alignment (fast or complete).
On the MCDU POSITION MONITOR page, read the deviation of each IRS position from the FMGC position and check that the value does not exceed values in the table in OMB.
Full alignment at beginning of day. Quick alignment if drift greater than values in table and on a crew handover.
Is it a requirement to check the flight deck oxygen on every turnaround?
Oxygen Mask Test – First Flight of the Day Only
