  • Aircraft Rerouting due to Abrupt Facility Outages: Case Study of 2011 Great Tohoku Earthquake, Japan
    Abstract: Abrupt airport outages resulting from terrorism or natural disasters can cause reroutes and fuel critical situations for flights. While aircraft carry reserve fuel for holding and diversions, poor situational awareness and incomplete information about conditions may cause disordered reroutes. We develop a deterministic routing model for airport outages that assigns flights an arrival time at a diversion airport. It includes a parameter for decision time, allowing us to investigate the value of faster response with advanced technologies. Our model minimizes flight time after the disaster, to ensure flights avoid fuel emergencies. Model formulations include an unconstrained allocation of flights to diversion airports, and a constrained allocation of flights according to routing rules; this formulation is suboptimal but provides a powerful tool because of its potential ease of implementation. We utilize the models to determine how coordinated Traffic Flow Management actions could have diverted flights and reduced fuel critical situations immediately following the destructive 2011 Tohoku earthquake. We find that, under reasonable assumptions about diversion airports and capacities, all flights can be accommodated without reaching a fuel critical state for a decision occurring 20 minutes after the disaster. A longer diversion decision making process results in some flights reaching emergency conditions, requiring the use of other, less preferred, diversion airports, and expedited handling procedures. The more constrained model requires faster response for full accommodation of flights. Because of the limited set of airports employed in this study, these results represent a conservative perspective on the potential outcomes for this decision-making paradigm.

    Submit a Discussion

    Attendees are welcome to submit a written discussion of any paper presented at the Annual Meeting. Written discussions will be considered for publication in the TRB Transportation Research Record series along with the paper being discussed. The author of the paper is given the opportunity to submit a written closure to the discussion. Please notify Rosa Allen at TRB by February 1, if you plan to submit a written discussion. When this notification is received, TRB staff will verify that the paper being discussed will be published and will provide the most recent version of the paper. This notification is therefore critical to ensure that all prepared discussions are used and to address issues in the most recent version of the paper in question.

    The discussion manuscript should be submitted to Rosa Allen by April 15 in electronic format as a Microsoft Word file (6.0 or later version). For the criteria used for discussions and for information on how to submit discussions for papers, see the Information for Authors document online at the TRB Annual Meeting website, under the Participant and Attendee Guides.
