The AP or FD in OP DES or DES mode can be used in approach. However, its use is only permitted if the FCU selected altitude is set to, or above, the higher of the two: MDA/MDH or 500 ft AGL.

The N1 limit depends on the ambient conditions and on the configuration of the engine air bleed. These parameters may limit N1 to a value that is less than the above-mentioned N1 value.

Engine Anti-Ice

The engine anti-ice must be ON during all ground and flight operations when icing conditions exist or are anticipated, except during climb and cruise when the temperature is below -40 °C SAT. The engine anti-ice must be ON before and during descent in icing conditions, including temperatures below -40 °C SAT.


Do not rely on airframe visual icing cues to turn engine anti-ice on. Use the temperature and visual moisture criteria specified in the icing conditions definition. Delaying the use of engine anti-ice until buildup is visible from the cockpit may result in severe engine damage and/or flameout.

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 1600 m(1 sm) or less, rain, snow, sleet or ice crystals).
  • Icing conditions also exist when the OAT on the ground and for takeoff is at or below 10 °C and 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.

Flight Controls

Parameter Value
Maximum operating altitude with slats and/or flaps extended 20 000 ft


Parameter Value
Minimum fuel at takeoff 1500 kg (3307 lb)

Landing Gear

Braking System

The braking system is not designed to hold the aircraft in a stationary position when a high thrust level is applied on at least one engine.

During ground procedures that require a thrust increase with braking, the flight crew must ensure that the aircraft remains stationary, and must be ready to immediately retard the thrust levers to IDLE.

Parameter Value
Maximum brake temperature for takeoff 300 °C

IR Ground Alignment

Possible only between 82° North and 82° South.

Magnetic Reference

In NAV mode, the IR will not provide valid magnetic heading and magnetic track angle:

  • North of 73° North, between 90° West and 120° West (magnetic polar region), and
  • North of 82° North, and
  • South of 60° South.

Flying at latitudes beyond these limits is prohibited.
