1. A method of adjusting a pressure value to account for an altitude-induced pressure effect, the method comprising:
- 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.
