Two runways. 21 bits of kit. One van.
Keep both runways open. Fix the kit before the traffic arrives.
Kit fails at random, several at once. Each aircraft on the Arrivals board needs every piece of kit for its runway working when it reaches the threshold. Runway kit (localiser, glidepath, PAPI, approach lights, RVR) only blocks its own runway. Airfield kit (radar, radios, voice rack, ground lighting and so on) blocks both. Drive onto a red pad and stay there until the ring fills.
The airfield is bigger than the screen. Red markers on the screen edge point to off-screen faults: red is urgent (blocking an arrival due within 15 s), amber can wait. The minimap shows the whole field. A red arrow by your van points to the most urgent job.
Each runway has its own crossing lights. Green: cross. Amber: get off now. Red: stop bar lit, stay behind it. On a runway at red is a runway incursion. The intersection counts as both runways. You can also go round the runway ends.
Scare birds and pick up FOD on a runway before something lands on it. Screws on roads give you punctures: change tyres at the MT BAY by the terminal. Keep clear of the fuel bowser, the baggage tug and the follow-me car (they stop at red too).
