G'day BOAC,
Thanks for the reply,
From 0.2 to 0.6 Mach you can ignore compressibility. The graph distinctly shows a decrease in alpha on the lift limit (from about 12 to 8 alpha over this speed regime) which also translates to an increase in forward stick to stay on the lift limit, ie buffet. I fly this aircraft and am simply interested in this phenomenon. Trying to understand how this is not a constant stick position with varying force to an actual unload if you like (while reaming at the lift limit)
Regards,
Bunghole.
