Standard atmosphere
ISA conditions at an altitude: 15 °C and 29.92126 inHg (1013.25 hPa) at sea level with the standard tropospheric lapse — the same constants behind the density-altitude sim (FAA-H-8083-25C ch 3/11; ICAO standard atmosphere).

How this is computed
ISA conditions at an altitude: 15 °C and 29.92126 inHg (1013.25 hPa) at sea level with the standard tropospheric lapse — the same constants behind the density-altitude sim (FAA-H-8083-25C ch 3/11; ICAO standard atmosphere). At 10,000 ft the standard day is −4.8 °C and 20.58 inHg.
