FCOM:
ICING CONDITIONS Applicable to: ALL
Icing conditions may be expected when the OAT (on ground and for takeoff), or when the TAT (in flight) is at or below 10 °C, and there is visible moisture in the air (such as clouds, fog with low visibility of one mile or less, rain, snow, sleet, ice crystals) or standing water, slush, ice or snow is present on the taxiways or runways. WARNING Pilots must turn on the engine anti-ice system, when temperature and visible moisture meet these criteria, and should not wait until they see ice building up.
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 maximum reverse thrust. Do not hold the nose wheel off the ground. ‐ If necessary, the maximum reverse thrust can be used until the aircraft is fully stopped.
This is for Cont. RWY .
Use your judgment , why on, maybe, short and wet runway you want to use just a little of your braking capability? Start with MAX-REV and AB-MED , then see the progress and , if needed adjust it manually.
