Wind direction largely determines runway use. For example, southerly winds typically bring Runways 17L/17R into use, while northerly winds reverse operations to 35L/35R. When wind conditions shift during the day, Air Traffic Control (ATC) may change the active runway configuration. This process requires careful coordination: arrivals may be rerouted, taxiing aircraft redirected, and departures sequenced to maintain safety and efficiency. Centennial’s three runways—17L/35R, 17R/35L, and 10/28—allow controllers to separate faster jet traffic from slower training aircraft, supporting a mixed-use environment safely and effectively.
The typical flight paths used at the airport are shown in the following interactive tool which is based around the different flow directions at the airport. This map is not live but rather shows a general snapshot of flow around the airport.
Arrivals
Centennial supports both Visual Flight Rules (VFR) and Instrument Flight Rules (IFR) arrivals. Most general aviation traffic—including flight schools, recreational pilots, and helicopters—operates under VFR, navigating visually while following ATC instructions to enter the traffic pattern. VFR pilots are sequenced into standard left or right traffic based on the active runway, and may receive instructions to extend downwind, enter base, or adjust speed for separation.
IFR arrivals, typically corporate or charter flights, follow routing and altitude assignments issued by Denver Approach. These aircraft may fly published instrument approaches or receive radar vectors to final, ensuring safe integration with both IFR and VFR traffic. In reduced visibility or instrument conditions, all arrivals operate under IFR. Centennial Tower coordinates traffic across multiple runways to maintain safe spacing and efficient flow.
Departures
VFR departures are common, particularly for local flight schools and recreational pilots. After receiving taxi clearance from Ground Control, VFR pilots contact Tower for takeoff clearance. They may remain in the pattern for training, proceed to practice areas, or depart to other airports. Slower aircraft and student pilots often use Runway 17R/35L, while faster jets and IFR traffic typically use Runway 17L/35R.
IFR departures receive clearance from Clearance Delivery, then Ground and Tower, and are assigned Standard Instrument Departures (SIDs) or radar vectors from Denver Departure. These aircraft maintain assigned headings and altitudes until further instructions, ensuring safe separation from VFR traffic and integration into controlled airspace over the Denver metro area.
Coordination between pilots and ATC is essential at Centennial, where VFR and IFR operations occur simultaneously. By managing sequencing, spacing, and runway assignments, ATC maintains safety, minimizes delays, and ensures efficient traffic flow across the airport’s busy and complex airspace.
Helicopters
Helicopters follow different flight paths than fixed-wing aircraft, allowing them to operate with greater flexibility. Unlike airplanes that rely on established runways and structured traffic patterns, helicopters can use designated helicopter routes that often keep them separate from the main flow of fixed-wing traffic. These routes may take them closer to the ground and over different areas surrounding the airport, which is why helicopters are often seen flying much lower than airplanes. This separation enhances safety while accommodating the unique performance and maneuverability of helicopters.
