Position PageThe second page in the GPS 12XL’s primary pagesequence is the Position Page. This page shows youwhere you are, what direction you’re heading, and howfast you’re going, and it’s most useful when you are trav-eling without an active destination waypoint. The graph-ic heading display at the top of the page indicates thedirection you’re heading (track) while you’re moving.Directly below this display are the track, speed, andtrip odometer (default) fields. Track is the compassdirection representing your course over the ground, orthe direction you’re moving. The lower left-hand cor-ner of the page shows your current latitude and longi-tude in degrees and minutes. The GPS 12XL uses thisbasic information to mark exact positions as waypoints,which help guide you from one place to another. Thelower right-hand corner of the page contains the alti-tude field (default). Below that field is a 12- or 24-hourclock.Both the trip odometer and the altitude fields areuser selectable, and both offer a trip odometer, triptimer, and elapsed time. This way, you can always besure of viewing this information regardless of theoption you’ve selected for the other user-selectablefield.The following user-selectable options are availableon the Position Page:Trip Odometer (TRIP)— total distancetraveled since last reset.Trip Timer (TTIME)— total (cumulative)time in which a ground speed has beenmaintained since last reset.Elapsed Time (ELPSD)— total time inhours and minutes since last reset.Average Speed (AVSPD)— average speedtraveled since last reset.Maximum Speed (MXSPD)— maximumspeed traveled since last reset.Altitude (ALT)— vertical distance abovemean sea level.15The speed and track dis-played on the PositionPage may fluctuate atslow speeds (or whenyou’re standing still)because of position errorscaused by DOD-imposedSelective Availability.REFERENCEPosition PageThe user selectable fieldson the Position Page giveyou a variety of informa-tion to choose from.
