pitot tubes -- the probes at the front of an airplane that help it calculate its windspeed, and whose icing-over can cause severe problems -- in terrestrial life:I got the chance this fall to climb up the observation tower at the Mount Washington Observatory on a clear but windy day--winds gusting to 100 and sustained around 60--and see their instrumentation there. (And to look down from a perch of 6300 feet at the near-sea-level valleys below.) With frequent winds in excess of 100 mph,[link widoczny dla zalogowanych], they use pitot tubes as their main wind speed indicator, and are often in the clouds with high winds, leading to severe riming conditions (it's not uncommon for rime to build up at a rate of several inches per hour, and for rime feathers, which are beautiful,[link widoczny dla zalogowanych], to reach lengths of two or more FEET). Much like on an airplane, they heat their pitot tubes, but sometimes high winds and cold temperatures team up to coat the instrumentation with ice, and can lead to reports of wind speeds near zero when, in fact, gusts are well over 100
