We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
rhhardin...even without any computers involved, it's essential for a pilot to know his airspeed. Too slow, and the wing loses lift (an aerodynamic stall, which has nothing to do with an engine stalling)...too fast, and the plane may break up in turbulence.
A speed readout from a GPS or other electronic nav system doesn't help, because that is giving pure groundspeed, and without other data sources cannot compensate for the effect of the wind.
