I don't think you can very accurately calculate indicated airspeed. The bes
t way to check that is on the bench. That's the reference for all the other
s.
If indicated is off, it's time to use the manometer and figure out which one
is accurate.

Thanks guys. This article will do.
Kit plane mag had an articles in Feb with a spreadsheet that used gps data t
o come up with errors. It is called a multipoint gps assisted AS calibration
. Do not have subscription to access the file.
Seemed like a good lazy alternative to do it with.

Here is a PDF file with a scale that translates inches of water to knots.
This simple rig is very accurate. It also serves to find pitot/static leaks
before you have the guy on the clock doing your biannual check.

This is just a guess since I don't read kit planes, but GPS is used along wi
th IAS and pressure/temp to calculate your TAS. I don't think GPS would be m
uch good for calculating IAS unless you knew very precisely the winds you ar
e flying in.

There are several programs available where you fly 3 different courses, note GPS
ground speeds, and the program calculates True airspeed, with the assumption
that the wind does not change while you make the measurements. Truth be told,
you can do just as well by finding the wind direction (max ground speed), then
do a 180 (minimum ground speed), and average the 2 numbers to get TAS. Note
the pressure altitude and the OAT, pull out your E6B and change TAS into IAS.
Water manometer is a good place to start, but it won't show static errors.

I do a pitot /static test on every third transponder check.. ie, every s
ix years.... The guy has the equipment already set up and it only adds 5
0 bucks to the bill... And his test rig is certified..... Well worth it
to me... YMMV... Ben Haas
