NAC specializes in establishing Declared Distance Standards for airport runways. The concept in establishing Declared Distance Standards is for airport owners to publish critical runway dimensions available for aircraft operations based on Federal Aviation Administration (FAA) standards. The definitions of Clearway, Stopway and Runway Safety Area, Runway Object Free Area and Runway Protection Zone are paramount to understanding the Declared Distance Concept.

NAC’s qualified, professional staff can implement Declared Distance Standards for an airport authority constrained by cost concerns and unable to modify a runway in order to accommodate necessary expansion while still meeting FAA airport design standards. The Declared Distance paradigm allows an airport to accommodate operations by larger and/or heavier airplanes within existing constraints on available land and still maintain an acceptable margin of safety.
 
Declared Distance Standards gives pilots exact runway information which assists them with calculations of acceptable loads and operational parameters for their individual airplanes. Any airport with these concerns should adopt Declared Distance Standards with the assistance of NAC.
