I have had this question for as long as I have been flying (1969) but have never pursued the answer because I have only ever flown certified aircraft with a manufacturer POH. However, I am flying our own-built RV-7A and the question is now front and center.
When determining the stall speeds of a homebuilt aircraft, when is the actual speed captured and what speed is used?
Is the speed captured at the pending stall (buffeting, etc.) or is it captured at the moment the wing falls? Is IAS or TAS generally used?
During testing, I captured the IAS at the moment the wing fell but, since I am calibrating an AFS AOA, which is dependent on the identified stall speeds, I want to make sure I am as accurate as possible.
Appreciate input!
