The OPT cannot do that unfortunately. It has the option to input a G/A clb gradient, but only for a "normal operation" with flaps 30 or 25, not 20.


FWIW our reference is OPS.29 (not that I expect it to match yours) and gives max temps and PA for both a F20 and F5 go around. I’d be surprised if a customer would elect to not have that info available.

I’m with wiggy, starting point would be F20 unless runway length/stopping performance was in question.
