Easy one

[R2000/1830]

X % climb == X Ft/Nm & X Ft/min

I used to know the formula but have forgotten it and cant find it.

[DBate]

% gradient x 60 = '/NM

e.g. 5% x 60 = 300'/NM

% gradient x GS = '/min

e.g. 5% x 200kt = 1000'/min

[R2000/1830]

thank you, i remember now

[R2000/1830]

sorry one more

feet/NM to Feet/min

[DBate]

FT/NM x (GS : 60) = ROC (or ROD) in FPM

Thanks again, I should really know this stuff but studying for the CX interview has turned by mind to mush.
