The temporary flight restriction (TFR) is a tool used by the U.S. government to define a certain area within the National Airspace System (NAS) where air travel is restricted or prohibited because of a security-related event, a temporary hazardous condition, or other special situations. The operational impacts of a TFR range from requiring a flight plan and two-way radio communication with air traffic control to a complete shutdown of the air space around the impacted area. When aircraft operations are restricted or prohibited, there are direct operational, economic, and environmental impacts. In some cases, local businesses, both on and off the airport, suffer significant losses. Aircraft routing may be affected, increasing fuel burn and emissions. While any part of the NAS can be impacted by a TFR (including airports, airspace, and navigation facilities), there is a specific need to develop a method to predict the impact of a TFR when the restricted airspace includes an underlying airport.
The objective of this research is to develop a comprehensive model to assess the operational, environmental, and economic impacts of a TFR. The model should allow users to tailor the analysis to account for the specific restrictions associated with a particular TFR and individual airport characteristics.
