NAVIGATION DISPLAYS (Cont)
BEARING POINTERS
The bearing pointers display bearing information from a selected navaid.
Two bearing pointers can be displayed on the compass rose or PPOS map format; one from number 1 bearing source, and
the other from number 2 bearing source. The bearing pointer from the number 1source is a cyan single lined pointer. The
bearing pointer from number 2 source is a white double lined pointer. Bearing icons are miniature representations of the
bearing pointers that are used to identify the actively selected bearing pointer. The bearing source display is blank if the
BRG source selection is OFF. The bearing pointer is removed from view when bearing source is invalid.
The source indicator and pointers are selectable through the BRG SRC push button on the DCP. The bearing source indicators
are displayed vertically in the lower left portion of the PFD. The selection box is moved with the MENU knob to
select the number 1 or number 2 bearing pointers. The PUSH SELECT or DATA knob is used to select the bearing source
or OFF.
As in the navigation source indicator, the bearing source indicator and bearing pointers show which bearing source is in use:
- VOR 1/VOR 2
- ADF 1/ADF 2
- FMS 1/FMS 2
- OFF (no display)
DISTANCE DISPLAY
The distance display shows the DME slant range distance to the navaid station.
When the DME H button is selected on the DCP, the held DME frequency replaces the AUTO annunciation on the NAV
CONTROL menu, the DME frequency can be tuned separately from the VOR frequency. When the DME transceiver is in
hold mode, a cyan “H” is placed beside the DME frequency in the NAV replaces the normally green “NM” on the PFD.
When the DME TEST control is selected, the TEST annunciation shows in large cyan text. The DME distance is 100 NM,
the TTG is 60 minutes, the station ID is AOK, and the ground speed is 100 knots. This test lasts about 10 seconds.
STATION IDENTIFIER
The navaid identifier is shown in the navigation data field above the distance display. Data for the identifier is supplied by
the DME. In DME hold, the identifier is removed from view.
NAVIGATION ALERT FLAGS
NAVIGATION SOURCE WARNING FLAG
A red boxed navigation source flag (VOR, LOC, and FMS) is displayed during a failure of the selected NAV source. The
navigation display is removed from view when the flag is displayed.
BEARING FLAG
Invalid data from the selected bearing source causes the bearing source annunciator to be replaced by a red boxed warning
flag. The bearing pointer is removed from view when the flag is displayed.
HORIZONTAL SITUATION INDICATOR (HSI)
The horizontal situation indicator (HSI) represents the compass card, which incorporates selectable navaids, bearing and
course pointers. HSI indications include:
- Course pointer
- Lateral deviation bar
- Lateral deviation scale
- To/from indicator

NAVIGATION DISPLAYS (Cont)
LATERAL DEVIATION SCALE
The lateral deviation scale has two dots on each side of the course arrow. Each dot represents:
- In VOR, 5° of deviation
- In LOC, 1° of deviation
- In FMS, 5 nautical miles
TO/FROM INDICATOR
The TO/FROM arrow is an outlined triangle on the course/desired track pointer. The arrow points toward the head of the
pointer to indicate a “TO” and toward the tail to indicate a “from”.
The color of the TO/FROM indicator is green for VOR onside information and amber for cross-side information.
In FMS mode the entire display is magenta.
AUTO FLIGHT CONTROL SYSTEM DISPLAY
The PFD presents automatic flight control system (AFCS) information consisting of flight guidance mode, autopilot mode
indications, and flight director command bars.
AUTOPILOT INDICATION
Autopilot information concerning engagement, disengagement and flight director in use is displayed in the top center portion
of the attitude display. A green AP indicates the autopilot has been engaged and the horizontal arrow points to the FD
coupled side.
A flashing red AP indicates that the autopilot has disengaged. The AP symbol flashes for five seconds and the aural cavalry
charge is heard. A white arrow indicates that the autopilot is not engaged and control of the FD is transferred to the indicated
side when engaged.
FLIGHT GUIDANCE MODE
Flight Guidance modes are displayed on the top center portion of the PFD, with three fields divided by thin vertical grey
lines. The left field of the line represents the lateral modes. The center field represents AP/YD engagement. The right side
