Thanks. I have that exact reference, but it does not explain what really happens.
Let's say you select speed well into the overspeed regime - 380 knots, for example. The FCOM reference says you will get VMO/MMO. With ATHR on the most you will actually achieve is approximately 6 knots below redline - not exactly VMO/MMO.
That's the question...where is there any reference to this apparent buffer below VMO/MMO?
Is there a fine point I'm missing on the subject of VMAX vs VMO/MMO?
If it worked as stated in the FCOM, then we should be able to see a speed equal to, but not greater than VMO/MMO.
