TAS calculation

[Mak]

Hi all,

Can someone explain me how to calculate TAS from IAS,temperature and altitude? I generally use the wheel for that and in the GA forum 2% increased per 1000ft was mentioned which is probably good enough for what I have in mind (calculations for an automatic inflight log) but would like to use something more exact.

Thanks.

You'll find the answer here (http://williams.best.vwh.net/avform.htm#Changes) .

It's one of the links in the initial 'sticky' on this forum.
