How this is computed
What your actual climb performance is worth over the ground: ft/NM = rate × 60 ÷ groundspeed, with the percent and X:1 forms alongside (1 NM = 6,076.115 ft). 500 fpm at 120 kt over the ground is 250 ft/NM — comfortably above a standard 200 ft/NM departure gradient, until a tailwind eats the margin.
