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
Example
This example uses a speed of 120 [kts].
Example
With a Speed of 120 [kts] the calculation would be as follows:
Rate Of Descent = 120 [kts] x 5 = 600
Check
What is the ROD (rate of descent) with a groundspeed of 220 kts?
220 kts x 5 = 1100 ft per minute
