I have an idea for a feature where if an ATC leaves the game, and the frequency switches to Unicom, then there will be a computer ATC that gives out only the most important commands such as
Cleared to Taxi(to any runway)
Cleared for Takeoff(in any direction)
Cleared to Land(ILS or GPS)
This is just so that airports do not become crazy after the switch to Unicom.
In PG, airports with 10+ airplanes have been switched to Unicom. Then, too many incidents happen.
