Question

Convert climb gradient from ft/NM to fpm

Answer 1

To convert climb gradient from ft/NM to fpm (feet per minute), multiply the climb gradient by the groundspeed in NM/hour and then by 60. Example calculation included.

Step-by-step explanation:

To convert climb gradient from ft/NM to fpm (feet per minute), you need to multiply the climb gradient value by the groundspeed in NM/hours and then by 60 to convert from hours to minutes. The formula is:

Climb Rate (fpm) = Climb Gradient (ft/NM) * Groundspeed (NM/hr) * 60

For example, if the climb gradient is 300 ft/NM and the groundspeed is 100 NM/h, then the climb rate would be:

Climb Rate = 300 ft/NM * 100 NM/h * 60 = 1,800,000 fpm
