Descend Calculation

Main calculation : 3 times height to lose plus 5 miles to slow and configure

i.e 20000ft to 5000ft = 15 x 3 = 45 miles + 5 = 50 miles.

Rate of descent required to be precisely on descend plan is 5 x ground speed

So, let say we have 250kts GS (ground speed) :  5 x 250 = 1250ft per minute

Happy landing!
