Went for another fly today and jotted down some speeds.
At 69.2T and FL 370 we we had a s/e drift down speed of 242 and a hold speed of 229. We were indicating 246kts at ci 10.
229 would have been about 10kts above the amber bar (which gives 40degrees bank to the stick shaker).
My assessment of that is that VMD was 13kts above the speed on the hold page which is the minimum fuel burn speed and not a speed I would have wanted to slow to.
Thoughts?
