>I didn't record the IAS
Paul - so, how do you know you were flying at the same speed on all
legs? Same throttle setting (wide open) and trim will only give the
same speed once stabilised at the same rate-of-climb (0, we hope).
Most of these TAS-from-GPS aids spring from the desire to determine
whether the IAS is suffering from errors of varous sorts, in
particular, installation-specific ones like position error.
I'm sure you'll enjoy repeating the lab work!
