I was wondering why > this is done when taking off in snowy condition? >From the ATR FCOM: If contaminant layere is significant enough to possibly accumulate in the brake area during ground operation, brake discs may join due to icing during the flight, leading to possible tyre damages at sub- sequent landing. [..] Before Landing: If take-off has been performed on a slush contaminated runway, this slush may seize the brakes during cruise. To prevent tire damage at touchdown: in final approach, after selection of GEAR DOWN, select anti-skid OFF, then pump brakes at least 5 times an then reselect anti-skid ON. By recycling the gear after T/O you get rid of some of the slush adhering to the brake assy and prevent freezing thus eliminate the cause for brakes seizeing up in the forehand.
