What is your suggestion?
Taxiway signs near important areas.
How would it work in the game?
There would be taxiway signs in front of runways, by terminals, and near other parts of the airport. They could warn about an ILS, the length of a runway, or what taxiway the aircraft is on or about to cross.
Why is this a good idea?
Taxiway signs would implement a new level of realism, as well as put the game up to real life safety standards.
