Our windsock in front of cabin and plane |
For one thing, even GPS systems rarely show
ground speed at destination. For
another, ours conks out below about +10 degrees on winter flights in our cold
Piper PA-20.
The first time this happened, my husband stuffed the tablet between his body and his quilted Carharrts to warm up, but it still did not turn on for 20 minutes, which happened to be the duration of the flight from the nearest airport to our home. Fortunately, this was a familiar route. But the mountainous terrain, rivers, glaciers, woods, and bogs result in very different wind, ice, snow, and temperature over very few miles, here. It is not safe to presume a condition at another location. The bright orange windsock next to a runway is, therefore, a welcome source of at least one piece of critical information.
