computed altitude

i. The indicated altitude corrected for installation and instrument errors. Also called calibrated altitude.
ii. A mathematical computation of the correct celestial altitude of a body at a specific geographic position, for a given date and time. This method helps the navigators quickly find a specific celestial body. Computed altitude is represented by the symbol HC .
