Office building where cockpit and cabin crews prepare for their flights e.g.:
-Cockpit crew flight-preparation at computer-desks
-Crew-briefing in briefing room.
-Security and passport check.
-Crew transport to plane by crew bus or by walk via terminal.
Why it should be implemented?
Most airports have crew rooms/bases to facilitate crew-flight-preparations for their major airlines. This adds a crucial feature to realistic airport management.
