Rate Of Climb - Conversion from Gradient
In order to calculate a required Rate Of Climb from a % Gradient, use the following formula:
Rule Of Thumb
Rate of Climb =
Gradient [%] x Groundspeed [kt]
Example with 4% gradient
In the chart it says you need to keep a 4% Gradient until 3000 ft.
Assuming you have a Groundspeed of 150 kts, the required Rate of Climb would be:
Rate Of Climb =
4 [%] x 150 [kts] = 600 [ft/min]
