SYSTEM OVERVIEW The following data may be selected for display in each of the four fields of the Navigation Status Box. • Bearing (BRG) • Distance (DIS) • Desired Track (DTK) • En Route Safe Altitude (ESA) • Estimated Time of Arrival (ETA) • Estimated Time En Route (ETE) • Ground Speed (GS) • Minimum Safe Altitude (MSA) • True Air Speed (TAS) • Track Angle Error (TKE) • Track (TRK) • Vertical Speed Required (VSR) • Crosstrack Error (XTK) • Fuel Over Destination (FOD) • Endurance (END) GPS CDI The GPS CDI Box on the System Setup 1 Page allows the pilot to define the range for the on-screen course deviation indicator (CDI). The range values represent full range deflection for the CDI to either side. The default setting is 'AUTO'. At this setting, leaving the departure airport the CDI range is set to 1.0 nm and gradually ramps up to 2 nm beyond 30 nm from the departure airport. The CDI range is set to 2.0 nautical miles during the en route phase of flight. Within 30 nm of the destination airport, the CDI range gradually ramps down to 1.0 nm (terminal area). During approach operations, the CDI range ramps down even further to 0.3 nm. This transition normally occurs within 2.0 nm of the final approach fix (FAF). If a lower CDI range setting is selected (i.e., 1.0 or 0.3 nm), the higher range settings are not selected during any phase of flight. For example, if 1.0 nm is selected, the system uses this for en route and terminal phases and ramps down to 0.3 nm during an approach. Note that the Receiver Autonomous Integrity Monitoring (RAIM) protection limits follow the selected CDI range and corresponding flight phases. The GPS CDI Box on the System Setup 1 Page displays the following: • Selected CDI range (auto, 2 nm, 1 nm, 0.3 nm) • Current system CDI range (2 nm, 1 nm, 0.3 nm) Changing the CDI range: 1) While on the System Setup 1 Page, press the FMS Knob momentarily to activate the flashing cursor. 2) Turn the large FMS Knob to highlight the SELECTED field in the GPS CDI Box. 3) Turn the small FMS Knob to display and scroll through the range list and press the ENT Key when the desired selection is highlighted. 4) Press the FMS Knob to deactivate the cursor. COM Configuration NOTE: 8.33 kHz VHF communication frequency channel spacing is not approved for use in the United States. Select the 25.0 kHz channel spacing option for use in the United States. The COM Configuration Box on the System Setup 1 Page allows the pilot to select 8.33 kHz or 25.0 kHz COM frequency channel spacing. 36 Garmin G1000H™ Pilot's Guide for the Bell 407GX 190-01255-00 Rev.
