So every time we fly ETOPS with the planned ETOPS diversion flight time of up to 240 minutes at 10000ft SE we shouldn't be there?
No, I didn't say that did I? You have probably got hold of the wrong end of the stick. My post was referring to where this thread started -
...Grid MORA is FL220 and your drift down is FL180. What would you do?
But as far as I am concerned, you can go wherever you like at 10,000'. Even when the MSA is 18,000' - just so long as I am not sitting down the back.
