so the exact page in the pic you posted doesn't exists. this is not a professional fully simulated product its not FSlabs and never was supposed to be. its more an aerosoft level aircraft. I agree its overpriced in comparison.
you can set your V1 VR V2 VAC VFS on the takeoff page. you can set your VREF VAPP VAC VFS on the landing page. you cant enter a setting for every flap combo you have to work out what you need and enter it.
