The following navigation terms are used on the GPS 500:
WPT 1
XTK
NORTH
WPT 2
BRG
GS
DIS
AIRPLANE
DTK
TRK
ALT(altitude)—Height above mean sea level (MSL).
BRG(bearing)—The compass direction from your 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 your
flight plan.
CUM(cumulative)—The total of all legs in a flight plan (such as “cumulative distance”).
DIS(distance)—The “great circle” distance from your 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).
DTK(desired track)—The desired course between the active “from” and “to” waypoints.
EFF(efficiency)—A measure of fuel consumption, expressed in distance per fuel units (e.g., nautical
miles per gallon).
ENDUR(endurance)—Flight endurance, or total available flight time based upon available fuel.
EPE(estimated position error)—A measure of satellite geometry quality and additional factors,
expressed as a horizontal position error in feet or meters.
ESA(en-route safe altitude)—The recommended minimum altitude within a ten mile radius of
your course on an active flight plan or direct-to.
ETA(estimate time of arrival)—The estimated time at which you will reach your destination
waypoint, based upon current speed and track.
ETE(estimated time en route)—The time it will take to reach the destination waypoint, from
present position, based upon current ground speed.
BRG(bearing)—The compass direction from your 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 your
flight plan.
CUM(cumulative)—The total of all legs in a flight plan (such as “cumulative distance”).

ETA(estimate time of arrival)—The estimated time at which you will reach your destination
waypoint, based upon current speed and track.
ETE(estimated time en route)—The time it will take to reach the destination waypoint, from
present position, based upon current ground speed.
