Firstly, just to confirm, on almost all the charts, I see the climb gradient required, and then also ROC in feet per minute. Basically all the calculations are done.
Are there any formulas anyone uses or is needed?
IF in the case Roc wasn't given, just multiply GS by required climb gradient which should give you the required ROC, if I'm not wrong..
Secondly, chart says for example if with a GS of 150 knots, You will need 800 FPM, do you use common sense to know if you can make that?
How do you even know what your GS wil be before you've taken off?
Some silly questions, I apologize.
Appreciate the input
