For the IRET & PICD wannabies, ponder this:
IAS is already compensated for instrument error, and this is calibrated for position/pressure error only to give CAS. Before IAS comes Airspeed Indicator Reading, ASIR. Wonderful stuff isn't it.....but more useful than t..s on a nun for the Europeeing licence!
And for Pof addicts: the effects of weight and configuration on speed stability.
Best speed stability = light & dirty
Worst speed stability = heavy & clean
Something about the best type of girlfriend comes in here.....
