You are the controller. Aircraft arrive low on fuel and departures wait at the gates. Every turn you issue runway clearances, then hit EXECUTE to advance the clock. Keep the metal moving — and never let two aircraft meet.
Select a flight strip → choose a runway button (or HOLD).
Arrivals burn 1 fuel per turn. Hit zero in the air = crash + a strike.
One aircraft per runway per turn. 14/32 physically crosses 09R/27L — you can't run both at once.
Heavies (777, A350, 747…) need the long runway (27R/09L) and leave wake turbulence, blocking that runway the next turn. The A380 Super blocks it for two.
Watch for weather closures and fuel / medical emergencies as levels climb.
