density correction

density correction

[′den·səd·ē kə′rek·shən]
(aerospace engineering)
A correction made necessary because the airspeed indicator is calibrated only for standard air pressure; it is applied to equivalent airspeed to obtain true airspeed, or to calibrated airspeed to obtain density airspeed.
(engineering)
The part of the temperature correction of a mercury barometer which is necessitated by the variation of the density of mercury with temperature.
The correction, applied to the indications of a pressure-tube anemometer or pressure-plate anemometer, which is necessitated by the variation of air density with temperature.

When density correction models and 6DoF propagation techniques are not available (e.g., because the object details are unknown or the measurements necessary for density corrections are unavailable), the drag coefficient [C.sub.d] and area-to-mass ratio A/m can be combined into one parameter called the ballistic coefficient (BC = [C.sub.d]A/m) that can be estimated from orbital data.

Since the building is located at an elevation of approximately 4,700 ft (1433 m) above sea level, an air density correction (CAIT) of 0.85 was used for the building automation system calculation.
The density correction factor accounts for the jet fan thrust degradation due to lower air density at elevated temperature compared to the standard air density conditions, under which the jet fans were rated.
