ALT (altitude) - Height above mean sea level (MSL).

BRG (bearing) - The compass direction from the present position to a destination waypoint.

CAS (calibrated airspeed) - Indicated airspeed corrected for instrument errors.

CTS (course to steer) - The recommended direction to steer in order to reduce course error or stay on course. Provides the most efficient heading to get back to the desired course and proceed along the flight plan.

CUM (cumulative) - The total of all legs in a flight plan (such as ‘cumulative distance’).

DIS (distance) - The ‘great circle’ distance from the present position to a destination waypoint.

DOP (dilution of precision) - A measure of satellite geometry quality on a scale of one to ten (lowest numbers are best, highest numbers are worst).
