(see Section 4.5). 2.6 VIEWING MESSAGES From time to time, the GPS 50 will use a message to tell you of conditions that need your attention. When the GPS 50 has a new message for you, the MSG banner will flash.
Keep in mind that the GPS 50 is not tracking satellites in the simulator mode. You should never attempt to use the simulator mode for actual navigation. If you are using your GPS 50 for the first time, we encourage you to review Chapter 3 which introduces the GPS 50's basic features. Additionally, you may wish to review Chapter 4 on custom setups.
3.1 POWER ON After you turn your GPS 50 on, it will conduct a series of self tests and display the following notices: “ GARMIN” . Following completion of the tests, the GPS 50 will begin acquiring satellites that will typically take two minutes to obtain a position fix.
The Satellite Status Page may be displayed by pressing the SET key. This page shows the number of satellites tracked and visible, dilution of precision (DOP), and estimated position error (EPE). DOP is a measure of the satellite geometry quality and hence the relative accuracy of your position (1 meaning the best and 10 meaning poor).
(see Section 4.11), as well as the altitude above mean sea level (MSL). When the GPS 50 is performing 2D navigation, the last known altitude will be used in the latitude/longitude computation. If the altitude is not accurate within a few hundred feet, you should manually enter your altitude.
3.4 AUTOSTORE Waypoint Name The AutoStore Page is displayed by pressing the ENT key while viewing the Position Page. This page allows you to capture your position at the touch of a button so that you may easily return later.

APPENDIX B NAVIGATION TERMS B.1 DEFINITIONS This section provides an illustration of and definitions for the navigation terms used in this manual.
Velocity/time terms: Ground speed. GS is the speed measured relative to the ground; also known as velocity over ground (VOG). Velocity made good. VMG is velocity in the direction of the desired course. It is the speed at which you are closing on the “ active to” waypoint.
B.2 COURSE TO STEER (CTS) Course To Steer is a GARMIN exclusive that recommends an optimal direction to steer that will guide you to the course and proceed efficiently along your route.
As an example, suppose you activate the route illustrated above. The GPS 50 chooses the closest leg with a desired track of 45 degrees but your position happens to be two nautical miles off course. The unit will automatically compute the optimal course to steer (which is 15° in this example). Press the NAV key until the CDI Page is displayed, then select “...
