CS 777-300er starting on it's on

So yesterday I loaded up the game and I was planning to fly the CS 777-300er down to Dubai from Toronto Intl and when I was in the game I spawned at a gate that I chose and when I went in the cockpit it was already on, everything was on without me doing anything for some reason, so then I restarted but everything was turned on by it’s self. And this happened for the first time for me so how can I fix it? I’ll tell if it was fixed when I play today.
