First of all well done on creating a good alpha. I have big hopes for your final product.
I would like to suggest a ground maintenance system. The idea is to crate a job for ground maintenance personal that keeps the runways and the stands in shape. They could even maintain the vehicle depot and pump stations. To me the current repair system is a little frustrating because it feels “fake”, meaning its only the click of a button and its done. To me it would be nice if you could hire people to service the airfield levels an structures.
I think if the vehicle could brake down an be serviced it will also add to the fun of a true airport simulation.
Thank you for listening.
Hope it is a realistic request
