Or if you have a min. climb of 500' per nm to 1500' and your GS is 150kts. how would you calculate?
Thank you.
500 feet per nautical mile divided by 6076' (one nautical mile) x 100 will give you the required climb gradient.
500/6076x100= 8.23%
Take your gradient times your groundspeed to get a climb rate in feet per minute
8.23x150= 1235 feet per minute
