ABSTRACT:
Methods and systems for adjusting a pressure value to account for an altitude-induced pressure effect. One method includes determining an average pressure value experienced at a first altitude, determining a ratio based on the average pressure value and a reference pressure value, determining a current pressure value experienced at the first altitude, and adjusting the current pressure value based on the ratio to obtain an altitude-adjusted pressure value.
