Elevation & Atmospheric Density

Mid-Altitude Plateau / Valley Facility

Operating at 4,170 ft (1,271 m MSL), true airspeed (TAS) on approach and takeoff roll is moderately higher than indicated airspeed (IAS). Engines experience slight thrust lapse under elevated summer temperatures, necessitating conservative density-altitude dispatch calculations for fully laden twin-engine commercial transports.
