B PREFACE GARMIN thanks you for selecting the industry's first high performance, full featured Personal NavigatorTM. [. . . ] If you wish to place the waypoint in a route, enter the desired route number. This route will be used for subsequent AutoStoreTM operations until it is changed or the route becomes full. If you attempt to place the waypoint in a route that already contains nine waypoints, you will be informed with the message "ROUTE IS FULL". 8-1 · · · If you do not wish to store the waypoint in a route, make sure the route number is blank. With the cursor over "OK?", press the ENT key. · See Section 12. 1 for an application example using the AutoStoreTM function. 8-2 CHAPTER 9 TRIP PLANNING The GPS 100 allows you to perform trip and fuel planning, and calculate aviation data such as vertical speed, true airspeed, and wind. These functions are accessed from Navigation Menu 1, illustrated below, which is displayed by pressing the NAV key. To select a function from this menu, place the cursor over the desired function and press the ENT key. NAVIGATION MENU 1 9. 1 TRIP PLANNING Waypoint/Route Selection From Waypoint To Waypoint Speed Distance Time Bearing TRIP PLANNING PAGE The Trip Planning Page allows you to calculate the distance, bearing, and time requirements between any two waypoints or for any programmed route. To perform trip planning between two waypoints. . . · Use the CLR key to select "WPT" on line 1. If you wish to use your present position, leave it blank. · · 9-1 · The speed field will display your present speed. You may enter a different speed to calculate time requirements. The GPS 100 will display the distance and bearing between the two geographical points. Use the cyclic field to select estimated time enroute (ETE) or estimated time of arrival (ETA). To perform trip planning for a programmed route. . . · Use the CLR key to select the desired route as illustrated below. (The waypoint/route selection field will cycle through all programmed routes containing 2 or more waypoints, i. e. , RT0 to RT9. ) Total/Leg Selection · The first and last waypoints, total distance, and ETA/ETE information will be displayed for the entire route, as indicated by "TTL". To display the distance, bearing, and ETA/ETE information for each individual leg, use the CLR key to change from "TTL" to the desired leg. (The leg field will cycle through every programmed leg, i. e. , LG1 to LG8, and the route total, TTL. ) · 9. 2 FUEL PLANNING Waypoint/Route Selection From Waypoint To Waypoint Speed Fuel Flow Time Fuel Required FUEL PLANNING PAGE The Fuel Planning Page allows you to calculate fuel requirements for any route you have programmed or between any two waypoints. 9-2 To calculate the fuel requirements between two waypoints. . . · · Use the CLR key to select "WPT" on line 1. You may enter a different speed to calculate time and fuel requirements. Enter the fuel flow in units per hour (e. g. , gallons per hour. ) · · · The GPS 100 will calculate fuel requirements in the corresponding units (e. g. , gallons) required to go from point 1 to point 2. Use the cyclic field to select estimated time enroute (ETE) or estimated time of arrival (ETA). You may calculate the fuel required for a programmed route in a manner similar to the trip planning described in Section 9. 1. 9. 3 DENSITY ALTITUDE/TAS Indicated Altitude Altimeter Setting Calibrated Airspeed Total Air Temperature Density Altitude True Airspeed DENSITY ALTITUDE/TAS PAGE The Density Altitude/TAS function will help you calculate critical aircraft performance data. · Enter the indicated altitude from your altimeter. 9-3 · Enter your calibrated airspeed. [. . . ] Errors in range measurements may result in disproportionately larger errors in position depending on the geometry of the satellites being used for navigation. A-1 When all GPS satellites have been deployed, 3D coverage with good geometry will be available 24 hours a day worldwide. Until then, there may be periods of time when only 2D coverage is available with occasional outages in coverage. A. 3 GPS RECEIVER DESIGNS Until now, most GPS receiver designs could be categorized as one of three types: · Continuous Receiverstypically consist of five or more channels with each channel dedicated to the tracking of one satellite. Receivers with this design provide the highest performance but are also large, expensive, and consume more power. [. . . ]
