Huzzah! This is a discussion that happens to be unusually pertinent for me.
I have seen that different manufacturers seems to define the minimum manuever speed differently. For instance, I've seen Brand X always calculate Vmin as 1.2 times the 1.3G buffet speed, While Brand Y seems to give about a constant 10 knot margin over the 1.3G speed (I guess that's to gain access to higher altitudes earlier?).
Anyone know if there's a prescribed/advised method for calculating the minimum manuever speed?
Out of curiosity Dagger, did your lookup table include an adjustment for off-ISA temperatures?
Thanks for the information spanner!
