54 Satellite Status Page The Satellite Status Page (the last NAV page) provides a visual reference of GPS receiver functions, including current satellite coverage, GPS receiver status, position accuracy, and displays your present position (by default, in latitude and longitude) and altitude. The Satellite Status Page also displays the cur - rent UTC time at the bottom center of the page. The altitude field (ALT) is user-selectable to configure the page to your own preferences and current navigation needs. GPS Receiver StatusSky View of satellite positionsSignal Strength Bars Satellite Numbers Horizontal Figure of Merit and Verti- cal Figure of Merit Estimated Posi- tion Uncertainty Acquiring Satellite, not ready for use Excluded Satellite Satellite acquired and used for position fix Satellite acquired, used for position fix, and has differ - ential corrections “INTEG” Annunciator (flagged when position not valid) Current Page in NAV Group (page position depends on options; see 400W/500W Series Display Interfaces Pilot's Guide Addendum) Current UTC Time The Satellite Status Page is helpful in troubleshoot- ing weak (or missing) signal levels due to poor satellite coverage or installation problems. You may wish to refer to this page occasionally to monitor GPS receiver performance and establish a normal pattern for system operation. Should problems occur at a later date, you may find it helpful to have an established baseline from which to compare. As the GPS receiver locks onto satellites, a signal strength bar appears for each satellite in view, with the appropriate satellite number (01-32, WAAS satel - lites will have higher numbers) underneath each bar. The progress of satellite acquisition is shown in three stages: • No signal strength bars — the receiver is looking for the satellites indicated. When the 500W-series unit is first powered on, an “Acquiring” status appears at the top of the page and no signal strength bars are displayed. • Hollow signal strength bars — the receiver has found the satellite(s) and is collecting data. • Cross-hatch cyan signal strength bars — the receiver has found the satellite(s) but it has been excluded by the FDE program as a faulty satellite. • Solid cyan signal strength bars — the receiver has collected the necessary data, but is not using the satellite in the position solution. • Solid green signal strength bars — the receiver has collected the necessary data and the satellite is being used in the position solution. The “D” character inside the bars indicates differ- ential corrections (e.g. WAAS) are being used for that satellite. The Time and other data may not be displayed until the unit has acquired enough satellites for a fix. Satellite Status Page 2 - NAV PAGES 190-00357-00 Rev K
55 Satellite Status Page As satellites are received, the status changes to “3D Navigation”. 3D Navigation includes altitude. The sky view display at the top left corner of the page shows the satellites currently in view as well as their respective positions. The outer circle of the sky view represents the horizon (with north at the top of the circle); the inner circle represents 45° above the horizon and the center point shows the position directly overhead. To change the user-selectable data field: 1. Press MENU to display the Satellite Status Page Options menu. 2. Turn the large right knob to highlight “Change Fields?” and press ENT. By default, current altitude (ALT) is displayed in the lower right corner of the page. This field is user selectable using the “Change Fields?” option. 3. Turn the small right knob to display the list of available data items. Continue turning the small right knob to select the desired data item from the list. Select a different data type from the list using the small right knob. NOTE: Do not rely solely on MSA as an absolute measure of safe altitude. Consult current charts and NOTAMs for your area. 4. Press ENT to select the desired data item and return to the position page. 5. Press the small right knob momentarily to remove the cursor from the page. To restore the user-selectable data field factory default setting: 1. Press MENU to display the Satellite Status Page Options menu. 2. Turn the large right knob to highlight “Restore Defaults?” and press ENT. 2 - NAV PAGES 190-00357-00 Rev K
56 Each satellite has a 30-second data transmission that must be collected (hollow signal strength bar) before the satellite may be used for navigation (solid signal strength bar). Once the GPS receiver has deter - mined your position, the 500W-series unit indicates your position, altitude, track and ground speed. The GPS receiver status field also displays the following messages under the appropriate conditions: • Searching Sky — The GPS receiver is searching the sky for ANY vis- ible satellites. You are also informed of this status with a “Searching the Sky” message. • Acquiring Sat — The GPS receiver is acquiring satellites for naviga- tion. In this mode, the receiver uses satellite orbital data (collected continuously from the satellites) and last known position to determine the satellites that should be in view. • 3D Navigation — The GPS receiver is in 3D navigation mode and computes altitude using satellite data. • 3D Differential Navigation— The GPS receiver is in 3D navigation mode and differential corrections are being used. The Satellite Status Page also indicates the accu - racy of the position fix, using Horizontal Figure of Merit (HFOM), Vertical Figure of Merit (VFOM), and Estimated Position Uncertainty (EPU). HFOM and VFOM represent the 95% confidence levels in hori - zontal and vertical accuracy. The lowest numbers are the best accuracy and the highest numbers are worse. EPU is the horizontal position error estimated by the Fault Detection and Exclusion (FDE) algorithm, in feet or meters. NOTE Operating outside of an SBAS service area with SBAS enabled may cause elevated EPU values to be displayed on the satellite status page. Regardless of the EPU value displayed, the INTEG annunciation is the controlling indication for determining the integrity of the GPS navigation solution. Dead Reckoning 2 - NAV PAGES 190-00357-00 Rev K
57 Dead Reckoning Dead Reckoning Dead reckoning is the process of continuing navi- gation using your last known position and speed after a loss of GPS navigation while on an active flight plan. CAUTION: Navigation using dead reckoning is there- fore only an estimate and should not be used as the sole means of navigation. Use other means of naviga - tion, if possible. Dead reckoning becomes active after a loss of GPS position while you are navigating using an active flight plan. A pop-up message will appear and you must clear the message before continuing operation. The ownship icon color is changed to yellow. The To/ From flag is removed from the CDI. The Dead Reckon - ing annunciator (DR) appears on the left side of the map display when GPS position is unavailable and the unit is in Dead Reckoning mode. All external outputs dependent on GPS position are flagged. Terrain will be noted as not available and new terrain advisory pop-ops will not occur. Traffic and Storm - scope information will not be shown on the Map page, but will continue to be available on their own dedi - cated pages. XM or FIS-B weather will still be available on the Map page. Dead Reckoning mode will continue until GPS posi - tion is restored, when GPS navigation is restored Dead Reckoning mode is exited. The DR annunciations will be removed and GPS information will be used to compute navigation related information for the current flight phase. Dead Reckoning is only allowed in En Route and Oceanic flight modes. If the unit is in a Terminal or Approach flight mode when Dead Reckoning takes place, “No GPS Position” will be displayed on the map pages and all navigation data will be dashed. If you are operating in Dead Reckoning mode and a transition to Terminal or Approach flight modes would occur from the projected Dead Reckoning position, Dead Reckon - ing mode will be discontinued. “No GPS Position” will be displayed on the map pages and all navigation data will be dashed. 2 - NAV PAGES 190-00357-00 Rev K
59 Section 3 Direct-To Navigation The direct-to function provides a quick method of setting a course to a waypoint. Once a direct-to is activated, the unit establishes a point-to-point course line (geodesic path) from your present position to the selected direct-to waypoint. The unit will provide navi - gation guidance to the selected direct-to waypoint until the direct-to is manually cancelled or replaced by a new active leg or direct-to. To select a direct-to waypoint: 1. Press the direct-to key. The Select Direct-to Waypoint Page appears, with the waypoint identifier field highlighted. Pressing the direct-to key displays the Select Direct-to Waypoint Page. 2. Use the small and large right knobs to enter the identifier of the desired direct-to waypoint. Use the small and large right knobs to enter the name of the direct-to waypoint. Press ENT once the name has been fully entered. 3. Press ENT to confirm the selected waypoint and ENT (again) to activate the direct-to func- tion. If you’re navigating to a waypoint and get off course, the direct-to function may also be used to re- center the CDI (HSI) needle and proceed direct-to the active waypoint. To re-center the CDI (HSI) needle to the active waypoint: 1. Press the direct-to key, followed by ENT twice. NOTE: When navigating an approach with the missed approach point (MAP) as the active way - point, re-centering the CDI (HSI) needle with the direct-to key cancels the approach.
