Vertical Navigation Question
Hi all, this is probably going to sound really simple but could someone be able to help me with the following question, its probably easy I just can't do it.
An aircraft is 15nm from the destination airfield at 3000ft QNH. It is necessary to descend to 1000ft QFE to be level 3nm before reaching the airfield, the elevation of which is 372ft. G/S in the descent will be 110knts. What ROD is required (assume 1mb=30ft).
It would be great if someone could point in the right direction for this one.Thank you for your time.
