Do we have to go to a cold start? When I switch to the An-2 I have engine running, morse code letter H is repeating and moving the cowl flaps switch with the mouse and roller does not increase or decrease the cowl flaps at all...same with the oil shutter. I can find no mention of audio signals in the manual so I've no idea what the "H" means. I'm wondering if I should have checked to see if there was a quick start option as I just don't have the time to pour over the manual in it's entirety.
might be the radio altimeter, left side console, front most dial, you can set that to whatever height you want it to go off, and it'll beep at you till your above that height. The main switch controlling it is the far right upper one before the co-pilots panel starts.
btw ... you can also break the gyros if you do a couple of barrel rolls
