FCOM Limitations Flashcards
What is the minimum fuel temperature (JET A1)?
-43 degrees Celsius
With the cockpit oxygen mask regulator set to NORMAL (diluted oxygen), during an emergency descent, what is the minimum number of minutes of oxygen that will be provided?
Depends on aircraft type. For NEO aircraft 15 minutes, for all cockpit members if oxygen bottle has appropriate pressure. For most non NEO aircraft, 13 minutes for all cockpit member if oxygen bottle has appropriate pressure.
What is the maximum altitude at which the APU can be started off batteries (ELEC EMER CONFIG)?
25,000’
Assuming normal electrical system operation, what is the maximum altitude for APU operation and restart?
Aircraft operating ceiling or 41,000’
What is the maximum altitude at which APU bleed pressure can be used for engine start?
20000’
What is time limit for TOGA thrust in the case of one engine inoperative?
10 minutes
What is the minimum engine oil temperature for takeoff?
CEO: -10 degrees Celsius.
NEO: 19 degrees Celcius
What is the maximum altitude the APU can be used for air conditioning and pressurisation?
Single pack operation: 22500’
Dual pack operation: 15000’
What restrictions are placed on First Officers with relation to cross-wind for takeoff and landing?
Max cross-wind 20 knots including gusts
What are the acceptable differences between the MCDU and charted vertical path and lateral track for an apprach using FINAL APP guidance?
0.1° vertical
Lateral tracks and distances should be reasonable & waypoints located in the correct position on the ND
What is the minimum RVR a First Officer can take off in?
550m
What is the normal RFFS required for A319/320 and when can this requirement be downgraded?
A319/320: 6
Departure/Destination: Can downgrade to 5 if aerodrome with low commercial traffic (annotated on flight plan)
Temporary downgrade by ATC/NOTAM not exceeding 72 hours: 2 categories below
Downgrade of alternate aerodrome: Non-UK - 4; UK - 5
Commander may decide to land at aerodrome regardless of RFFS if safer than diverting
What distance/time can you fly from a suitable aerodrome?
Can’t fly greater than 60 mins from suitable aerodrome at OEI cruise speed in ISA
A319: 380NM
A320: 400NM
What are the time/distance requirements for a take off alternate?
Take off alternate must be within 1 hour OEI cruise speed ISA still air based on actual take off weight
Maximum 320NM
What is Vmo and Mmo?
350kts
M0.82
What cloud ceiling and visibility do you require to conduct a visual approach?
Cloud ceiling >2500’ OR circling minima if higher
5km visibility
What are the approach stability criteria?
