Next to the b button to fix altitude not working,something seems off with the starting of engines.Yesterday I wanted to start the engine with crtl+e on the boeing ,going for frequent flyer miles achievement on steam ,& it only was able to start engine 1 and 2 using the key combo. The message to start engine kept popping for 3& 4.I fixed it manually by searching for a tutorial how to start the other 2
I also had it on the jet plane Cessna Citation CJ4 before,but was able to start it manually without tutorial in that one.
