Is this the same college room mate that proved Bernouli's Law wrong? I can't 
comment on sailboats but as far as a Boeing 767, I fly my final approach 
airspeed the same in Mexico City or Denver as I do in Kona or Honolulu. I make no 
adjustment to my indicated airspeed(IAS), what I read on my speedometer, for 
any altitude I happen to fly. There is however a difference in true 
airspeed(TAS). The higher my altitude the higher my TAS. In other words, I'm actually 
going faster across the ground to get the same IAS when I'm shooting an approach 
at an airport with a higher altitude, everything else being the same ie. winds. 
At Kona, to register a 140 knot IAS approach speed, I'm actually registering 
a 140 knot TAS. At Denver, I might be up to 150 knots of TAS for the same 140 
knot IAS.

What's all this mean? Your room mate and I suspect you as well are full of, 
well, tacos;-) A 40 knot Lake Dillon breeze has the same affect that a 40 knot 
Rio de Janeiro blow would have. 

Hap, talkin dahkine Wahoo in Evahboost, Maguire
