FAA increasing air traffic control staff, supervisors at Ronald Reagan Washington National Airport

The FAA will review DCA's arrival rate of aircraft per hour, which is "disproportionately concentrated within the last 30 minutes of each hour," according to the agency.

Spacing between each flight is required to keep operations safe, according to the MWAA. 

In March, the FAA announced it would permanently restrict "non-essential" helicopter operations around DCA, and eliminate helicopter and fixed-wing mixed traffic.

It also prohibited the simultaneous use of runways 15/33 and 4/22 when helicopters conducting urgent missions are operating near DCA.

The team will offer confidential support to staff "following stressful events," according to the statement.

Regular wellness checks will also be conducted at the facility.

The FAA did not immediately respond to a request for comment.
