The flight path marker can be enabled or disabled through the setup menus. See the SkyView
System Installation Guide for information about this setting. In order to calculate and display
the Flight Path Marker, SkyView requires an indicated Airspeed that is not zero or a GPS ground
speed of more than 25 kts. The flight path marker also uses vertical speed, magnetic heading,
GPS ground speed and ground track to calculate its guidance.
Several examples of Flight Path Marker behavior:

If the aircraft’s nose is pitched up, but the marker stays on the horizon, this indicates
that the aircraft is not climbing or descending. You will see this behavior during slow
flight.

If the aircraft is neither climbing nor descending, the flight path marker will align with
the zero pitch line. Many aircraft do not cruise at an exactly level attitude. In this case, it
is normal to have a slightly pitched up or pitched down attitude indication, even though
the flight path marker indicates the aircraft is indicating no vertical trajectory.

If the marker is to the left or right of the attitude indicator’s aircraft symbol, this
indicates that the path over the ground is different than the direction the aircraft is
pointing. This depicts the effects of wind or a slip attitude.

If the aircraft is climbing out of a canyon and the marker is above the terrain ahead, this
indicates that the aircraft, at its current trajectory, will clear that terrain.

If the aircraft is climbing out of a canyon and the marker is overlaid on the terrain
ahead, this indicates that the aircraft, at its current trajectory, will impact the terrain.

If the marker is pointed at a runway threshold during an approach, that is where you will
be when you land if you keep the same approach path to the runway.
