Simultaneous Parallel Runway Operations

August 24, 2000

Notice from:

U.S. Department of Transportation, Federal Aviation Administration, Southern Region
DeKalb Peachtree Air Traffic Control Tower, Chamblee, GA 30341

Background:

During a Full Facility Evaluation it was identified that FAA Order 7110.65, paragraph 3-8-3, requires 700' between runway centerlines to conduct simultaneous same direction operations on parallel runways with larger than twin engine props. DeKalb Peachtree Airport (PDK) has 500' between the centerlines for Runway 2L/20R and 2R/20L. With the existing centerline separation, PDK may conduct simultaneous same direction parallel runway operations with twin engine propeller driven aircraft or smaller; however, simultaneous operations with larger than twin engine props are not authorized.

Procedures:

Effective immediately, discontinue simultaneous same direction operations on Runway 2L/20R and Runway 2R/20L when either aircraft is larger than a twin engine prop. Simultaneous operations are defined as aircraft arriving and/or departing on the parallel runways and on the runway at the same time. The intent of the interpretations, which was received during the evaluation, is that the Agency does not want aircraft wingtip to wingtip on final, landing roll or departure roll. Simultaneous operations do not include aircraft taxiing, crossing, or in position and holding on the parallel runway. Simultaneous operations are not authorized when either aircraft is larger than a twin engine prop.
