    SECTION 2: NAV PAGES 2.1 MAIN PAGE GROUPS The GPS 400’ s main pages are divided into four separate page groups: NAV, WPT, AUX, and NRST (Table 2-1). Each page group is comprised of multiple pages. The page groups are selected using the large right knob. The individual pages are selected using the small right knob.
  • Page 28: Nav

    SECTION 2 NAV PAGES 2.2 NAV PAGE GROUP The NAV Page Group includes seven pages (Figure 3-2). While viewing any NAV page, turn the small right knob to select a different NAV page. The pilot may find this selection process convenient to cycle between the Default NAV Page and the Map Page, two of the most frequently used pages.
  • Page 29 NOTe: The GPS 400 always navigates TO a waypoint unless the OBS switch is set (preventing automatic waypoint sequencing), or the aircraft has passed the last waypoint in the flight plan. Directly below the CDI appears the active leg of the flight plan, or the direct-to destination when using the Direct-to Key.

The Position Page also features a reference waypoint field, located at the bottom of the page, to indicate the bearing and distance to/from a selected waypoint.
  • Page 48 SECTION 2 NAV PAGES Press the ENT Key to select the desired type and return to the Position Page. To select between ‘bearing FROM’ or ‘bearing TO’ to the reference waypoint, turn the small right knob to select the desired bearing reference (Figure 2-45) and press the ENT Key.
  • Page 49: Satellite Status Page

    2.8 SATELLITE STATUS PAGE The Satellite Status Page provides a visual reference of GPS receiver functions, including current satellite coverage, GPS receiver status, and position accuracy. The Satellite Status Page (Figure 2-47) is helpful in troubleshooting weak (or missing) signal levels due to poor satellite coverage or installation problems.
  • Page 50 SECTION 2 NAV PAGES Each satellite has a 30-second data transmission that must be collected (hollow signal strength bar, see Figure 2-48) before the satellite may be used for navigation (solid signal strength bar, see Figure 2-47). Once the GPS receiver has determined the current position, the GPS 400 indicates position, track, and ground speed on the other navigation pages.
  • Page 51: Vertical Navigation Page

    2.9 VERTICAL NAVIGATION PAGE The GPS 400’ s Vertical Navigation Page (the last NAV page, see Figure 2-49) allows the pilot to create a three- dimensional profile which guides the pilot from the present position and altitude to a final (target) altitude at a specified location.
  • Page 52 SECTION 2 NAV PAGES Turn the small right knob to select ‘Above Wpt’ (AGL) or ‘MSL’, (Figure 2-52) and press the ENT Key. ‘Above Wpt’ uses the altitude of a destination airport as stored in the Jeppesen NavData Card. ‘MSL’ lets the pilot set a specific target altitude for any waypoint category: airport, VOR, NDB, intersection, or user waypoint.
  • Page 53 With the profile set, the vertical speed required (VSR) is displayed on the Vertical Navigation Page. Expect the following to occur when using the vertical navigation feature: • At one minute prior to reaching the initial descent point, a message ‘Approaching VNAV Profile’ occurs.

  • Page 55: Section 3: Direct-To Navigation

    SECTION 3: DIRECT-TO NAVIGATION 3.1 OVERVIEW The GPS 400’ s direct-to function provides a quick method of setting a course to a destination waypoint. Once a direct-to is activated, the GPS 400 establishes a point-to- point course line (great circle) from the present position to the selected direct-to destination.
  • Page 56 SECTION 3 DIRECT-TO NAVIGATION Selecting a Destination by Facility Name or City In addition to selecting a destination by identifier, the Select Direct-to Waypoint Page (Figure 3-4) also allows the pilot to select airports, VORs, and NDBs by facility name or city location.
  • Page 57 Selecting a direct-to destination from the active flight plan: Press the Direct-to Key. The Select Direct-to Waypoint Page appears, with the waypoint identifier field highlighted. Turn the large right knob to highlight the flight plan (FPL) field (Figure 3-6). Figure 3-6 Highlighted Flight Plan Field Turn the small right knob to display a window showing all waypoints in the active flight plan (Figure 3-7).
  • Page 58 SECTION 3 DIRECT-TO NAVIGATION Shortcuts Shortcuts are available when using the Direct-to Key, allowing the pilot to bypass the use of the small and large right knobs to enter the destination waypoint’ s identifier. A direct-to can be performed from any page displaying a single waypoint identifier (such as the WPT pages for airports and NAVAIDs), or from pages that display a list of waypoints (e.g., the Nearest Airport Page).
  • Page 59 Selecting a Direct-to destination from the Map Page Direct-to destinations may also be selected from the Map Page. If no airport, NAVAID, or user waypoint exists at the desired location, a waypoint named ‘+MAP’ is automatically created at the location of the panning pointer.
  • Page 60 SECTION 3 DIRECT-TO NAVIGATION Specifying a Course to a Waypoint When performing a direct-to, the GPS 400 sets a direct great circle course to the selected destination. The course to the destination can also be manually defined using the ‘CRS’ course field on the Select Direct-to Waypoint Page. Manually defining the direct-to course: Press the Direct-to Key.
  • Page 61: Section 4: Flight Plans

    SECTION 4: FLIGHT PLANS The GPS 400 lets the pilot create up to 20 different flight plans, with up to 31 waypoints in each flight plan. The Flight Plan Page Group consists of two pages (Active Flight Plan Page, Figure 4-1, and Flight Plan Catalog Page, Figure 4-2), accessed by pressing the FPL Key.
  • Page 62 SECTION 4 FLIGHT PLANS A blank Flight Plan Page appears for the first empty storage location (Figure 4-4).

  • Page 190 SECTION 10 ADDITIONAL FEATURES Pilots should be aware of TAS/TCAS system limitations. If an intruder transponder does not respond to interrogations due to antenna shading or marginal transponder performance, it will not be displayed, or display may be intermittent. Pilots should remain vigilant for traffic at all times when using TAS/TCAS systems for non-transponder equipped airplanes or unresponsive airplanes.
  • Page 191 Aural Alerts A TA consists of a displayed traffic symbol (solid yellow circle) and an aural alert. The aural alert announces “traffic”, followed by the intruder aircraft’ s position, altitude relative to own aircraft (“high”, “low”, or “same altitude”), and distance from own aircraft; e.g. “traffic, 12 o’clock, high, 3 miles”.
  • Page 192 SECTION 10 ADDITIONAL FEATURES Switching Between Standby and Operating Modes The unit must be in operating mode for traffic to be displayed. The ability to switch out of standby into operating mode on the ground is especially useful for scanning the airspace around the airport before takeoff.
  • Page 193 Altitude Display Mode The GTS 8XX has four altitude display modes (Figure 10-24); Normal (±2,700 ft), Above (-2,700 ft to +9,000 ft), Below (-9,000 ft to +2,700 ft), and Unrestricted (±9,900 ft). The GTS 8XX continues to display up to 30 intruder aircraft within its maximum surveillance range, regardless of the altitude display mode selected.
  • Page 194 SECTION 10 ADDITIONAL FEATURES Traffic Warning Window When the unit is not on the traffic page and the GTS issues a Traffic Advisory, the Traffic Warning Window (Figure 10-26) is displayed, which shows a small thumbnail map.

  • Page 236 APPENDIX C TROUBLESHOOTING When should I use the OBS key to return to auto sequencing, and what happens when I do? The most common application for using the OBS Key is the missed approach. The GPS 400 suspends automatic waypoint sequencing (indicated by a ‘SUSP’ annunciation directly above the OBS Key;...
  • Page 237 When does turn anticipation begin, and what bank angle is expected? The GPS 400 smooths adjacent leg transitions based upon a nominal 15º bank angle (with the ability to roll up to 25º) and provide three pilot cues for turn anticipation: 1) A waypoint alert (‘NEXT DTK ###°’) flashes in the lower right corner of the screen 10 seconds before the turn point (Figure C-6).
  • Page 238 APPENDIX C TROUBLESHOOTING Why does my CDI not respond like a VOR when OBS mode is active? Unlike a VOR, the CDI scale used on GPS equipment is based on the cross-track distance to the desired course, not an angular relationship to the destination (Figure C-8).
