How to plan your descent to a landing (if you are going less than 120kts)

How many miles out should you descend?
First how many 1000s of feet you do you need to lose? mulitply that 1000 number by 3 and that is how many miles you should start your gradual descent.

  • or example you are at 6500 feet and need to descend to pattern alt 1500 feet you need to loose 5000 feet mulitply 5 x 3 = 15 miles out you need to descend
At what rate should you descend?
Take half your groundspeed and mulitply by 10.
  • you are flying at 100kts, half is 50 x 10 = 500fpm
