A30:Descent Profile Calculations
Hi everyone!
I am doing my supis as of now and one thing just keeps me boggling is the computation of the descent profile.I understand how to calculate the TOD ie.your FL multiplied 3+10 nm for deceleration +/- one third of HW or TW. 1)Beyond this how do I check whether I am high or low on profile?
2)The distance calculated by the above formula should be checked against the VOR dist on ND or on the MCDU.
3)there are some other calculation if ATC is giving you a straight in approach or vectoring you around.How to cater for these calculations?
4)When calculating descent profile do we take the airport elevation or the platform altitude?
