Elevation & Atmospheric Density

Mid-Altitude Plateau / Valley Facility

Operating at 3,962 ft (1,208 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.
