CDS -- PFD - VERTICAL SPEED INDICATIONS Vertical Speed Indications
The vertical speed indication shows vertical speed from the inertial reference section of the onside air data inertial reference system (ADIRS). Vertical speed shows as a white pointer against the vertical speed scale. The total display range is +/- 6000 feet.
If the vertical speed is more than 400 feet per minute, then vertical speed also shows as a digital value. This digital value is to the nearest 50 feet. The digital value shows above the vertical speed scale if it is a positive vertical speed. It shows below the vertical speed scale if it is a negative vertical speed.
You can select target vertical speed from the DFCS mode control panel. It shows as a bug on the left of the vertical speed display and is magenta in color. The bug is two lines with a center reference point.
The TCAS resolution advisories show on the vertical speed scale. A TCAS climb advisory shows as a red bar that extends from the bottom of the vertical speed scale. A TCAS descend advisory shows as a red bar that extends from the top of the vertical speed scale.

Heading Indications The heading indication on the primary flight display (PFD) shows heading/track data on a partial compass rose. selected heading bug and the digital readout are magenta in color.
Heading Indication
Current heading from the inertial reference section of the onside air data inertial reference system (ADIRS) shows as a triangular pointer at the top of the compass rose. There are indices every 5 degrees and numerical readouts every 10 degrees.
The heading reference (MAG or TRU) shows to the right of the heading indication. MAG or TRU show in green. When TRU shows, a white status box shows around the TRU annunciation. When you change from TRU to MAG, a green highlight box shows around the MAG annunciation for ten seconds.
Track Indication
Current track from the flight management computer system (FMCS) shows as a line that extends to the compass rose. It is white in color.
Selected Heading
The pilot uses the DFCS mode control panel to set the selected heading, which shows by a heading bug on the compass rose. A digital readout of the selected heading also shows to the left of the heading indication. The

CDS -- PFD - FLIGHT MODE ANNUNCIATIONS Flight Mode Annunciations
These are the types of flight mode annunciations (FMA):
- Autothrottle
- Roll
- Pitch
-Autopilot status. Autothrottle Mode Annunciation
The autothrottle mode annunciation shows in column one of the FMA. These are the autothrottle modes that can show:
- N1
- GA
- RETARD
- FMC SPD
- MCP SPD
- THR HLD
- TEST
- ARM.
All autothrottle modes show in green. This does not include the ARM mode that shows in white. A green highlight box shows around the autothrottle mode for ten seconds when the mode changes.
Roll Mode Annunciations
The roll mode annunciation shows in column two of the FMA. Two lines of annunciation are available. The first

line shows the active roll mode. The second line shows the armed roll mode.
These are the active roll modes that can show:
-HDG SEL
-VOR/LOC
-LNAV.
All active roll modes show in green. A green highlight box shows around the roll mode for ten seconds when the mode changes.
VOR/LOC is the only armed roll mode. It shows in white.
Pitch Mode Annunciations
The pitch mode annunciation shows in column three of the FMA. Two lines of annunciation are available. The first line shows the active pitch mode. The second line shows the armed pitch mode.
These are the active pitch modes that can show:
-TO/GA
-V/S
- ALT ACQ
- ALT HOLD
- VNAV SPD
- VNAV PTH
- MCP SPD
-G/S -FLARE.
