Rate Of Descent - Final Approach

Calculate the Rate Of Descent on final approach with this rule of thumb:

Rule Of Thumb

Formula for a 3° Glideslope

Rate Of Descent = Groundspeed [kts] x 5


This example uses a speed of 120 [kts].


With a Speed of 120 [kts] the calculation would be as follows:
Rate Of Descent = 120 [kts] x 5 = 600


What is the ROD (rate of descent) with a groundspeed of 220 kts?

220 kts x 5 = 1100 ft per minute
