Runway Safety Area (RSA) EnhancementsRunway 1-19

Solicit input from agencies and the public •

Identify significant environmental issues to be analyzed • in greater depth

Eliminate from detailed study issues that are insignificant • or have been covered by prior environmental review

Set temporal and geographic boundaries for impact analysis•

Identify available technical information and additional • reasonable alternatives, if any

Identify necessary permits, licenses, approvals, authorizations •

Clarify areas of special expertise•

Runway Safety Area (RSA) EnhancementsRunway 1-19

In order to comply with Federal Aviation Administration (FAA) Order 5200.8 and FAA Advisory Circular 150/5300-13, the Authority is examining the configuration of the Runway 1-19 Runway Safety Area (RSA) at Ronald Reagan Washington National Airport.

The proposed enhancements to the Runway 1-19 RSA will bring the RSA into compliance by the 2015 FAA deadline.

Preliminary Purpose & Need

Runway Safety Area Enhancements

Ronald Reagan Washington National Airport

PUBLIC INFORMATION WORKSHOP ENVIRONMENTAL ASSESSMENT SCOPING JULY 30, 2008

Runway Safety Area (RSA) EnhancementsRunway 1-19

Definition: A defined surface surrounding the runway intended to provide a measure of safety in the event of an aircraft’s excursion from the runway by significantly reducing the extent of personal injury and aircraft damage during overruns, undershoots, and veer-offs.

Standard RSA Dimensions for Aircraft Using DCA 500 feet wide•

600 feet prior to the landing threshold•

1,000 feet beyond the runway end •

Compliance Deadline is 2015 (2006 Transportation Appropriations Act)•

Congress and Department of Transportation (DOT) Office of Inspector General • continually monitor FAA and airport progress
