Bird strike and runway closure during a peak arrival bank
At Viru Viru (VVI), runway 15/33 is the only runway. At 16:20, a landing A320 reports a bird strike on short final and a possible tyre damage; the aircraft stops on the runway, unable to vacate. The tower declares the runway closed. Three arrivals are in the terminal area: a 737 at 8,000 ft descending, a Dash 8 at 6,000 ft, and a Cessna Citation jet at FL180 descending. Two departures are holding at the threshold. The airport has no parallel runway and no radar vectoring capability beyond the terminal area. The airport fire service is responding. Weather is VMC, wind 160/08, visibility 10 km.
1. What is the controller's sequence of actions in the first five minutes, and how should the three arrivals be handled?

First five minutes:
- Confirm the runway is blocked and record the time. Instruct the A320 to confirm its position and whether it can move; if not, declare the runway unusable and notify the tower supervisor, the fire service (already responding), and the approach/area sectors.
- Stop departures. The two aircraft at the threshold must be held; do not let them line up.
- Handle arrivals by priority. The 737 at 8,000 ft is closest to the field and lowest on fuel margin; the Dash 8 at 6,000 ft is lower but slower; the Citation at FL180 is highest and has the most options. Issue holding instructions at published holding fixes with assigned levels and EFC times. If no holding fix is convenient, use a racetrack over a VOR or a procedural orbit clear of the airport.
- Give information, not just instructions. Tell each aircraft the runway is closed due to an aircraft on the runway, the expected delay is unknown, and ask for fuel endurance. That lets the crews make diversion decisions.
- Prepare diversions. Identify the nearest suitable alternate within the aircraft's fuel range and coordinate with that unit before the crews ask.
Judgement point: do not promise a reopening time. The controller does not control the recovery; the fire service and the operator do. Giving a false estimate encourages crews to hold past their fuel reserve.
2. The Dash 8 reports it can hold for 20 minutes and then must divert. The 737 reports 35 minutes. How does the controller use this information, and what does it do if the runway remains closed at 20 minutes?

The reports convert an open-ended delay into a planning constraint.
- The Dash 8's 20-minute limit sets the decision point: at 16:40 the Dash 8 must be either landing or diverting. The controller should plan for the Dash 8 to divert unless the runway is clearly about to reopen by 16:35.
- The 737's 35 minutes gives a second decision point at 16:55.
- The Citation at FL180 has the most fuel but is also the highest; it can be kept high and is the least urgent.
At 20 minutes with the runway still closed: instruct the Dash 8 to divert to its nominated alternate, obtain the diversion clearance, coordinate the handover, and release it. Do not hold it 'a few more minutes' on the hope of reopening; that is how fuel emergencies are created. Simultaneously, confirm with the fire service an estimate and pass it to the 737.
If the Dash 8 declares minimum fuel or an emergency, it gets priority for the first available runway or, if the runway is physically blocked, for the longest available surface or a diversion with priority handling. The controller must not delay a declared emergency to preserve sequence.
