Is there a way to open the cargo door in the cockpit or can it only be opened by the lever outside of the aircraft?
If you are using SPAD.neXt or A&O you can bind a button or switch to B:UNKNOWN_CARGO_DOOR and it will work from either inside or outside of the aircraft, including the pilot’s seat. I use SPAD and set the button press value to 1 and it acts as a toggle each time I press it, either to open or close. I stopped using MSFS 24 control settings all together as it is a frustrating and colossal waste of time. Spad took me a while to figure out, but there are a ton of great tutorials on YouTube and once it clicks in your mind, you will never go back to the in-sim controls. Just my 2 cents, cheers.
