well i m getting the answer as 1230 fpm
the way i calculated is that i first found out ground speed by using tas, track and wind dir and speed via flight calculator.
i got gs as 180kts
then took hori distance and divided it by speed to get time which i got as 13 mins
then i divided 16000 feet by 13 mins and i got the answer as 1230 fpm
well is this method and answer correct????
