Winter flying with retractable gear?

Paul,

Tapping the brakes prior to retraction is one of aviation's old wives
tales that just hangs in there. The gear wells are large enough to
hold the tires even if they have some bulge from spinning (which isn't
much anyway on our slow little bugsmashers). There are some
transports in which the manual calls for tapping the brakes and some
in which it specifically says not to as the sudden stop on large tires
and wheels can cause the tire to slide on the rim.

Check the manual for your airplane for winter operations. Some
suggest to delay gear retraction for a bit to help blow off
snow/slush/water. The inertia from the spinning tire usually tosses
off most of the contamination (allowing it to freeze to the underside
of the wing g) and waiting a bit to suck the gear up allows the
airflow to take it off the brake discs and other, stationary, portions
of the gear. Having the gear freeze up is pretty rare. More common
will be that you'll taxi through some snow that gets on the brakes, it
melts on the discs and then freezes one or both of the brakes after
takeoff. Just land on centerline to give yourself room for a swerve
as it takes a moment or two of sliding tire(s) before the brake
unfreezes and you have rolling control. Naturally, it occurs when you
make one of those lucky, smooth touchdowns and you hear the squeal of
a tire sliding, then the pop as the ice lets go and things go back to
normal. Not usually a big deal, but folks have gone into the
snowbanks adjacent to the runway due to not reacting quickly enough.

All the best,
Rick

This will be my first winter flying the club's Lance. One instructor told
me that you want to tap the brakes before retracting the gear to dislodge
any slush or snow so that it doesn't freeze in the wheel well, and I read
somebody else saying that you should hold off retracting the gear after
take-off for a little while to blow the slush and snow off. Should I do
one or the other or both?
