Centennial Airport (KAPA/APA)

Centennial Airport (KAPA) is the primary general aviation reliever for Denver, sitting 13 miles southeast of downtown in the suburbs of Englewood and Greenwood Village. It is consistently among the top five busiest GA airports in the United States, and for charter brokers it is the practical Denver answer to bizjet operations — KDEN is so far from the city core and so airline-congested that almost every private movement in the Denver metro routes through KAPA instead. Four FBOs (Signature, Modern Aviation, TAC Air, and Jet Center) handle the traffic.

The runway environment is straightforward — 17L/35R at 10,002 feet is typically long enough for large-cabin and ultra-long-range jets — but the operating environment is anything but. KAPA's field elevation is 5,883 feet, and density altitude on a hot Colorado summer afternoon (90°F+ on the ramp is common in July) can push effective performance altitudes north of 8,500 feet. That matters enough that most flight departments based at KAPA run formal runway-analysis software, and brokers booking heavy-jet charters out of KAPA in summer routinely confirm tankering and payload assumptions in writing. Approaches to the Front Range can also be turbulent in winter when downslope winds pour off the Rockies — a known, briefable hazard but one that occasionally drives weather diversions.

Centennial Airport is a public use airport owned by the Arapahoe County Public Airport Authority in the Denver metropolitan area, 15 nmi southeast of downtown Denver, Colorado, United States. Located primarily in Dove Valley, a census designated place (CDP) in Arapahoe County, the airport extends into Douglas County, with some of those portions in the Meridian CDP.
