The GARMIN GPS 150 is a powerful navigational tool that provides pilots with accurate navigational data and provides a host of database information at their fingertips. The next few pages are designed to familiarize you with the operation of the GPS 150, including powering up the unit, entering data and doing a simple direct-to. This section also briefly covers the Position and CDI navigation pages, which will be used for most of your in-flight navigation. Once youre familiar with what the keys and knobs do, consult the reference section of the manual for instructions on specific tasks, and an overview of what the GPS 150 can do for you. This introduction uses the GPS 150s simulator mode, so it can be performed at home or at the office using the optional AC adaptor. If you have changed any of the factory default settings (position format, units of measure, selectable fields, etc.), the pictures used may not match your configuration. Powering up the GPS 150 Turn the GPS 150 on by rotating B (the power/ brightness knob) clockwise. Notice that rotating it clockwise will also brighten the display. This knob locks the NavData card in place, so it may not be removed while the unit is on. After you turn the unit on, the Welcome page will be displayed while the unit performs a selftest. When the self-test is complete, you will be prompted to select which operating mode you would like, either Simulator or Normal. Simulator mode will enable all of the functions of the GPS 150, but will not acquire satellites and use calculated position information or navigational guides. Simulator mode will allow you to mark, create, edit and store waypoints and routes. The operating mode screen will NOT be displayed when using aircraft power. Although you may use the GPS 150 inside the cockpit if main power is off, it is not recommended to keep you from accidentally navigating the aircraft using Simulator mode. If aircraft power is lost during flight, the GPS 150 will automatically switch to its internal battery to provide safe navigation information for up to four hours.

Getting Started

Power On
Pictures in the left and right columns are actual screens taken from the GPS 150. Some screens may vary slightly if you have changed any of the unit settings.

Position page

The CDI page is the main page used while navigating to a destination. It contains information including the active waypoint, ground speed, track, course deviation indicator (CDI), distance and estimated time enroute (ETE). These fields will typically only contain information if you have selected a destination (performed a direct-to or activated a route) and a speed. In our simulated trip, we will begin at Bakersfield Municipal Airport and go to Delano Municipal Airport.

CDI page

Going to the Destination

To perform a direct-to at any time: 1. Press D. (For our simulated trip we will go to KDLO, Delano Municipal). 2. Rotate K until K is displayed. 3. Rotate O one position to advance the cursor. 4. Repeat steps 2 and 3 until KDLO is displayed. 5. Press E to accept the entry.
This will bring up the Waypoint Confirmation page again, but this time, it will contain the Delano Municipal Airport information.
1. Press E to confirm the direct-to.
Entering the direct-to waypoint identifier.
This brings you back to the CDI page, which will allow you to enter a ground speed toward the destination. The waypoint you have selected as your destination will now be referred to as the active to waypoint.
To set a ground speed from the CDI page: 1. Press C to obtain a cursor.
The CDI page after the waypoint has been confirmed.
2. Rotate O to highlight the ground speed (gs) field. 3. Using K to change the data, and O to move the cursor, enter a ground speed of 140 knots. 4. Press E when finished.
The CDI page after a ground speed has been set.
This will calculate and display the ETE and distance as you approach the destination. The CDI page also displays the course deviation indicator in the lower left part of the display. The CDI slides horizontally to show the direction and distance you are off course (in simulator mode, it will always be on course). The default is for the CDI to deflect full scale at 5 distance units (mi, km, etc.) of crosstrack error. Crosstrack error is the distance you have deviated from the course set when you activated the destination waypoint.

Page 5

The CDI page contains three fields which may be configured to display other information. The dis field can be configured to display any of the following: dis Distance to destination waypoint str Steer direction and distance away from established course The trk field can be configured to display any of the following: trk Track angle brg Bearing to waypoint cts Course to steer (to get back on course most efficiently) dtk Desired track obs Omni-directional Bearing Select (Inbound Course Select) trn Turn angle The ete field can be configured to display any of the following: eta Estimated time of arrival ete Estimated time enroute trk Track angle vn Vertical navigation You can change these fields by highlighting them with the cursor and rotating K until the desired data is displayed. This is covered completely in Section 1, page 13. Any time you would like to set a direct course for a destination, simply highlight the waypoint identifier and press D. This can be done from any page. It will cancel any active routes, vertical navigation, or offset navigation that may be in effect. This is especially useful when locating the nearest airport, and setting a direct course for it. To display the nearest airport, press T. After the nearest airport is displayed, you may perform a direct-to and begin navigating towards that destination.
