How is runway use determined at DIA?
Runway use is determined by variables such as weather, capacity, airport layout, aircraft performance, noise abatement procedures and aircraft density in the surrounding airspace. When wind conditions allow, traffic density and arrival/departure streams determine the runway use at the airport to ensure the most expeditious and safe flow of air traffic. Each morning at DIA, ATC sets the airports flow for the day, based on the prevailing winds. Due to the complexities of re-routing aircraft to alternative runway ends, the flow is not changed unless wind conditions require it. Why do some aircraft seem louder than others? Aircraft operating at DIA have a diverse range of noise levels. These noise levels primarily depend on the type of engine used by the aircraft, the size of the aircraft and whether the aircraft is taxiing on the airfield, landing or taking off. Current versions of Stage 3 aircraft tend to be the quietest aircraft in the fleet. Older Aircraft with Stage 3 “hush kitted” en
