APU Bleed Use With Air Start Unit
The Flight Crew must not use bleed air from the APU BLEED and from the HP Air Start Unit at the same time, to prevent any adverse effect on the Bleed Air System.
Why? B/c causes overpressure issues (two sources)
Cabin Pressure:
Max Positive Differential Pressure
9 PSI
Cabin Pressure:
Max Negative Differential Pressure
-1.0 PSI
Packs Use With LP Air Conditioning Unit
The Flight Crew must not use conditioned air from the **packs ** and from the LP Air Conditioning Unit at the same time, to prevent any adverse effect on the Air Conditioning system.
Why? B/c causes overpressure issues (two sources)

Min Height for AP -
In All Other Phases
500 ft AGL (A319/A320)
900 ft AGL (A321)
The use of AP or FD in OPEN DES or DES mode is only permitted in approach, when the FCU altitude is set at or above, the higher of the two:
Highest of:
MDA/MDH or 500 ft (A319/A320)
MDA/MDH or 900 ft (A321)
Why? b/c in OPEN DES, you’ll be at THR IDLE, speed is controlled by pitch, thrust won’t be able to spooled up
NAV mode may be used in the terminal area, 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 cross-checked with navaid raw data.
A319/A321: If one engine is inoperative, it is not permitted to use the autopilot to perform NPAs (non-precision approaches) in the following modes:
- FINAL APP
- NAV V/S
- NAV/FPA
- *Only FD use is permitted.
APU Start
After three consecutive APU start attempts, the Flight Crew must wait 60 min before a new start attempt.
