FLIGHT INSTRUMENTS
When a bearing pointer is displayed, its associated information window is also displayed. The Bearing
Information windows (Figure 2-22) are displayed to the lower sides of the HSI and give the following
information:
• Bearing source (NAV, GPS, ADF)
• Pointer icon (single line for BRG1, double line for BRG2)
• Frequency (NAV, ADF)
• Station/waypoint identifier (NAV, GPS)
• GPS-derived great circle distance to bearing source
When the NAV radio is tuned to an ILS frequency the bearing source and the bearing pointer are removed
from the HSI and the frequency is replaced with "ILS". When NAV1 or NAV2 is the selected bearing source,
the frequency is replaced by the station identifier when the station is within range. If GPS is the bearing
source, the active waypoint identifier is displayed instead of a frequency.
The bearing pointer is removed from the HSI and NO DATA is displayed in the information window if: the
NAV radio is not receiving the tuned VOR station or if GPS is the bearing source and an active waypoint is
not selected.
When the Arc HSI is displayed, the Bearing Information windows and pointers are disabled.
Selecting bearing display and changing sources:
1) Press the PFD Softkey.
2) Press a BRG Softkey to display the desired bearing pointer and information window with a NAV source.
3) Press the BRG Softkey again to change the bearing source to GPS.
4) Press the BRG Softkey a third time to change the bearing source to ADF (note: ADF radio installation is
optional).
5) To remove the bearing pointer and information window, press the BRG Softkey again.
DME INFORMATION WINDOW
DME radio installation is optional.
NOTE:
The DME Information Window (Figure 2-22) is displayed above the BRG1 Information Window and shows
the DME label, tuning mode (NAV1, NAV2, or HOLD), frequency, and distance. When a signal is invalid,
the distance is replaced by "–.– – NM". Refer to the Audio Panel and CNS Section for information on tuning
the radios.
Displaying the DME Information Window:
1) Press the PFD Softkey.
2) Press the DME Softkey to display the DME Information Window above the BRG1 Information Window.
3) To remove the DME Information Window, press the DME Softkey again.
