Recent accquisition, very much enjoying it. Recently took it from La Menara, Marrakech, over the High Atlas to Ouarzazate, and interesting "hop" for Light/Medium aircraft, which I have done a couple of times, sadly not as pilot. My preferred route takes me to 13,600 ft. I got the "dark screen" warning. Now looking for a way to set the cabin pressurisation, but can't identify. Any help would be appreciated. I survived, btw, but had to come down a little earlier and quicker than I normally would.
