CROSSWIND
Applicable to: ALL
To optimize directional control during the low speed phase of the takeoff and landing roll and
according to the reported braking action given by the control tower, it is not recommended to take off
or to land with a crosswind component higher than :
Reported Maximum crosswind (kt)
braking action
Reported runway
friction coefficient Takeoff Landing
Equivalent runway
condition *(1)
Good (on wet runway) ≥ 0.4 29 33 1
Good/medium 0.39 to 0.36 29 29 1
Medium 0.35 to 0.3 25 2/3
Medium/poor 0.29 to 0.26 20 2/3
Poor ≤ 0.25 15 3/4
Nil 5 4/5
(1) Equivalent runway condition (only valid for maximum crosswind determination)
1. Dry, damp or wet runway (less than 3 mm water depth)
2. Runway covered with slush
3. Runway covered with dry snow
4. Runway covered with standing water with risk of hydroplaning or wet snow
5. Icy runway or high risk of hydroplaning
Note: The maximum crosswind values given in the above table are recommended values based
on computations. They are given without gust.
TAXIING
Applicable to: ALL
FOLLOWING TAXIING PROCEDURES..............................................................................CONSIDER
‐ Avoid high thrust settings.
‐ When taxiing on slippery surfaces, stay well behind preceding aircraft.
‐ Taxi at low speed. Note that antiskid does not operate at low taxi speeds.
‐ On slippery taxiways during turns with large nose wheel steering angles, noise and vibration may
result from the wheels slipping sideways. Keep speed as low as possible to make a smooth turn
with minimum radius. Differential power may be needed.

If taxiing in icing conditions with precipitation on runways and taxiways contaminated
with slush or snow :
Before takeoff keep flaps/slats retracted until reaching the holding point on the takeoff runway
to avoid contaminating the mechanism. Hold the BEFORE TO checklist at FLAP SETTING and
finish it after extending flaps/slats.
When taxiing in after landing, do not retract the flaps/slats to avoid damage of the structure.
After engine shutdown make a visual inspection to determine that the flap/slat mechanism is free
of contamination.
When the mechanism is clean, use the following procedure to retract the flaps/slats before the
aircraft electric network is de-energized :
• Set the YELLOW ELEC PUMP to ON
• Check that the BLUE ELEC PUMP is in the AUTO position
• Set the BLUE PUMP OVRD to ON
• Retract the FLAPS and monitor retraction on ECAM page.
• Select off the YELLOW ELEC PUMP and BLUE PUMP OVRD and resume with normal
procedure.
Note: On contaminated runways and taxiways, ‐ the radio altitude indications may fluctuate and
auto call outs or GPWS warnings may be activated. Disregard them.
‐ During taxi on snowy runways, the radio altimeters may not compute any data and the
ECAM warnings ’DUAL ENG FAILURE’, ’ANTI ICE CAPT TAT FAULT’, ’ANTI ICE F/O
TAT FAULT’, ’L/G SHOCK ABSORBER FAULT’ may be triggered. Disregard these
warnings.
TAKEOFF
Applicable to: ALL
FOLLOWING TAKEOFF PROCEDURES........................................................................... CONSIDER
‐ For contaminated runways, select MAX TO.
‐ Do not abort takeoff for minor deficiencies even at low speeds.
If you have to abort takeoff, maintain directional control with the rudder and small inputs to the
nose wheel. If necessary, use differential braking to regain the center line when stopping distance
permits.
‐ Do not lift the nose wheel before VR in an attempt to avoid splashing slush on the aircraft,
because this produces additional aerodynamic drag.
‐ Rotate, lift off and retract gear and high lift devices in the normal manner.

LANDING
Applicable to: ALL
FOLLOWING LANDING PROCEDURES............................................................................CONSIDER
Avoid landing on contaminated runways if the antiskid is not functioning. ‐ The use of autobrake
LOW or MED is recommended provided that the contamination is evenly distributed.
‐ Approach at the normal speed.
‐ Make a positive touchdown after a brief flare.
‐ As soon as the aircraft has touched down, lower the nose wheel onto the runway and select
