2.5% of 120 is 3 kts.
So that's about 300 fpm...
Way to complicated when you can just multiply your GS at Vfs/Vyse/V2 by the climb gradient.

IE at Vyse of 106 in nil wind (PA31-350) and a MA 2.5% climb gradient requires around 265 fpm. (Yeah right hahaha good one) :)

3 deg slope just use half ground speed in feet per minute, 120 kts= 600ft per min, 180 kts = 900 ft per min etc, makes approaches easy. Also know your wizz wheel. After 13000 hrs still carry one and use it regularly. Great for diversion calculations, something we do a lot at the RFDS.
