4.10.1 SV Display Elements
4.10.1.1 Zero Pitch Line - ZPL
The Zero Pitch Line (ZPL) is a white line on the Attitude Display that represents the
horizon, similar to the horizon line on an attitude indicator. The center of the ZPL is
removed to present a clear view of the center of the Synthetic Vision display
(Figure 4-117). Terrain above the aircraft’s altitude is presented above the ZPL while
terrain below the aircraft’s altitude is presented below the ZPL.
4.10.1.2 Flight Path Marker - FPM
The Flight Path Marker (FPM) displays the aircraft’s lateral and vertical flight path
(Figure 4-118). The FPM position is derived from the GPS ground track and vertical
speed. When the FPM intercepts terrain, an obstacle, or a runway, this indicates that the
aircraft is tracking in three dimensions toward that feature. When the FPM is above the
Synthetic Vision terrain, this indicates the aircraft will clear that terrain. When the FPM
is held on the ZPL, the aircraft is maintaining its current altitude. The Flight Path Marker
can be removed from view to reduce display clutter. The Flight Path Marker can be
Enabled/Disabled in the Menu.
To display or remove the Aircraft Reference Symbol on the MFD
1. Press the MENU button and rotate the Right Knob to the SV SETTINGS page.
2. Press the FLIGHT PATH MARKER Menu Key and rotate the Right Knob to the
desired setting (ENABLE or DISABLE).
