Climb gradient
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).
Reading the screen: cyan is a value you entered, green is a computed result, amber means a field still needs input or the entry needs a CHECK. SOLVED lights when every result is computed; STO keeps a value to reuse in another function; the line-select keys beside the screen pick the field the keypad edits.
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.
