Thx old smokey!
So 11581 was the actual altitude (true) after correcting for the 998mb, right? Have you used the 27.5'/mb?How about the transfer from 2103m to 6900'? Do you use 3.28'/1 meter?
Let me give you another one, I hope I'll get the idea then:
A/C flies over mountains 4730m AMSL.
Track is 140(M) ("not sure why they give it") and QNH is 995mb.The required clerance is a minimum of 1500'.What's the minimum FL in cloud?
Here they say assume 1mb=27'
Thanks again!
