Extrapolation of VMCa to minimum weight
Hello,
I would like to know if some of you have ever participated to VMCa testings.
I have found in the FTG from CS-23 or FAR-23 guidance for extrapolating a value obtained at a given density altitude to SL - ISA conditions (it's quite easy since it's just a kind of thrust correction).
However, this method doesn't propose any correction to account for the aircraft (since VMCa is determined at a 5° bank angle, but cannot always be tested at the certification minimum weight).
If any of you has developped a method to account for the weight in VMCa determination from flight tests, a few tips would be appreciated.
thanks!
