Autopilot/Flight Director use of OP DES or DES modes on approach
FCU must be set to or above the higher of MDA/H or 500 AGL
FMGS Lateral & Vertical NAV certified for…
- After takeoff, en route, and terminal area ops
- Navigation within RNAV/RNP airspace
- Instrument approaches (except ILS, LOC, LOC B/C, LDA & final approaches)
- Missed approach procedures
Use of NAV mode after takeoff…
Can use provided:
- GPS PRIMARY is available, or
- Flight crew checked the FMGS takeoff updating
Use of NAV mode in terminal area…
Can use provided:
- GPS PRIMARY is available or
- the appropriate RNP is checked or entered on the MCDU and HIGH accuracy is displayed, or
- FMS navigation is crosschecked with NAV aid raw data
Use of NAV mode for Approaches based on Radio Navaids…
Can be performed in NAV, APP NAV or FINAL APP provided:
- if GPS PRIMARY is available, the navaid may be u/s
- if GPS PRIMARY is not available, the navaid must be serviceable, tuned and monitored during the approach
Use of NAV mode for RNAV Approach…
- RNAV(RNP) approach may be performed with GPS PRIMARY not available only if the navaid coverage supports the RNP value and HIGH accuracy is displayed on the MCDU with the specified RNP
- RNAV(GNSS) may be performed if GPS PRIMARY is available
Non-Precision approaches OEI
A319 only:
- Not permitted to use the autopilot in FINAL APP, NAV V/S, or NAV/FPA
- FD use is permitted
Max altitude with flaps/slats extended
20,000 ft
Min fuel quantity for takeoff
3307 lbs
Braking system…
Is not designed to hold the a/c stationary with high thrust on one engine.
Crews must ensure the aircraft remains stationary and be ready to immediately retard the T/L to IDLE.
Max brake temp for takeoff:
- fans off
- fans on
- 300 oC
- 150 oC
APU Start
After 3 consecutive starts, must wait 60 mins
TO/GA Thrust time limits:
- All engines
- OEI
- 5 mins
- 10 mins
Oil temperature:
- Max continuous
- Max transient (15 min)
- Min starting
- Min before takeoff
- 140 oC
- 155 oC
- -40 oC
- -10 oC
Min Oil quantity
9.5 qt + estimated consumption
Avg consumption 0.5 qt/hr
Engine starter limit
- auto start includes up to 3 start attempts per cycle
- 20 sec pause required between successive cycles
- 15 min cooling period required after 4 failed cycles
- starter must not be run when N2 is > 20%
FLEX takeoff…
- is permitted if a/c meets all perf requirements
- is permitted with INOP items provided penalties are applied
- is NOT permitted on contaminated runways
- TFLEX cannot be:
— higher than TMAXFLEX (ISA + 53oC). TFLEXMAX corresponds to a reduction of 25% from full rated TO thrust
— lower than the flat temp (TREF)
— lower than the actual OAT
Reverse thrust
- in flight use prohibited
- backing the aircraft with reverse is prohibited
- max reverse should not be used below 70 kts. IDLE REV can be used to aircraft stop.
