Signature Flight Support at Washington Reagan National Airport (DCA) logged 33 business aviation operations on November 16, its largest tally since the days before the 9/11 terrorist attacks. Since the airport reopened to business traffic in 2005–some four years after the attacks–it has operated under the strict guidelines of the DCA Access Standard Security Program (DASSP), which limits business aviation operations at the airport to 48 per day. According to Signature, the spike earlier this month was tied to a business roundtable meeting scheduled in Washington, D.C. Otherwise, DCA’s business aviation traffic has been slowly climbing to approximately 12 aircraft movements a day. “What we look forward to is hitting that [30-movement] milestone on a more regular basis because when we get to that we’ll go back to the TSA and petition for more than 48 operations,” said Mary Miller, Signature’s vice president of industry and government affairs. The number of domestic “gateway airports” funneling traffic to DCA has nearly doubled over the past year to 65. “I think the trend line is going to continue to chart up here,” Douglas Hofsass, deputy assistant administrator for the TSA’s transportation sector network management, told AIN.
