[s-cars] MAF location

[mlp]

Reading further on, is this the answer Hap?
 
"....All airplanes have an airspeed indicator. Glancing at it, the pilot
knows when to pull the stick back and fly the airplane off of the ground.
And the required airspeed is always the same regardless of the ground speed
or density altitude. If it takes 60 mph for a plane to fly, it will always
take an indicated 60 mph on the airspeed indicator. The actual ground speed
might be 70 mph or greater, but the airspeed is the same. Always. The
airspeed indicator measures the number of air molecules entering the pitot
system. ...."

The sailboat didn't have a pitot system, and as far as I know, (a) wasn't
trying to get airborne at the time and (b) was measuring wind speed relative
to the surface of the lake, not the boat.  I realize a sail is "like a wing"
but I believe part of the equation involves "wind power density" (e.g.
http://www.awea.org/faq/windpower.html ) which seems to call for some
consideration of mass or density, in addition to just wind velocity.

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.
