yankiwi,
According to the answers in the bok you're right on the money!
So I gather you correct by 1% for every 10 degrees deviation from ISA?
R.
Let me correct myself:
4% for every 10 degress? again, the answer does show 9550ft.
Old smokey:
True Altitude = 9856.9 ft (7086.9 ft above station). This all assumes that the QNH was given by the station and correct for the station elevation.
Can you explain the calculation?
Thanks
