FLIGHT MANAGEMENT FUNCTION
DEGRADED SITUATION
If GPS PRIMARY LOST is displayed on the ND and MCDU, the navigation accuracy remains sufficient for RNP operations provided that,
the RNP value is checked or entered on the MCDU and HIGH ACCURACY is displayed.

LIMITATIONS
ENGINES
STARTER
‐ A standard automatic start that includes up to two start attempts, is considered one cycle
‐ For ground starts (automatic or manual), a 35 s pause is required between successive cycles
‐ A 15 min cooling period is required, subsequent to three failed cycles, or 15 min of continuous or
cumulated crank
‐ The starter must not be run when N2 is above 20 %.
LIMITATIONS
ENGINES
REVERSE THRUST
- Selection of the reverse thrust is prohibited in flight.
- Backing the aircraft with reverse thrust is not permitted.
- Maximum reverse should not be used below 70 kt. Idle reverse is permitted down to aircraft stop.
REDUCED THRUST TAKEOFF
FLEX TAKEOFF
TFLEX cannot be:
‐ Higher than TMAXFLEX, equal to ISA + 50 °C.
‐ Lower than the flat temperature (TREF).
‐ Lower than the actual OAT.

The use of GA SOFT mode is prohibited with
one engine inoperative
Maximum operating altitude with slats and/or flaps extended

DEFINITION OF ICING CONDITIONS
Icing conditions exist when the OAT (on ground or after takeoff) or the TAT (in flight) is
at or below 10 °C and visible moisture in any form is present (such as clouds, fog with visibility of 1 sm (1 600 m) or less, rain, snow, sleet or ice crystals).
operating on ramps, taxiways or runways where surface snow, standing water or slush may be ingested by the engines, or freeze on engines, nacelles or engine sensor probes.

TAXI WITH DEFLATED OR DAMAGED TIRES
In addition, if tire damage is suspected, the flight crew must ask for
aircraft inspection prior to vacate the runway or taxi. If the ground crew suspects that a tire burst may damage the landing gear, maintenance action is due.
