By now, most pilots are well aware of the peril they face from snow- and frost-encrusted wings. The increased friction and resulting compromised lift can render an otherwise clean airplane unflyable -- and you wouldn't know until you reach liftoff speeds, only to find that Bernoulli has taken that morning off. So almost all of us know that you need to clear the wings -- and tail surfaces -- of all traces of snow, ice and frost. For those of you with hangars, you get a pass on this unpleasant chore at home base. But before you start feeling too smug, consider that you could find your precious metal bird outside on an overnight trip -- especially an unexpected overnight stay off the beaten path. Do you have what you need on board for the morning clean-up? If not, be sure to ask the FBO if someone will be on hand before your departure with a broom, an ice scraper and whatever else you might need to get the job done.
