2. Course mode (CRS) – provides vector navigation as illustrated below. CRS also
allows tracking an autopilot-selected course when the host GPS route function is not in
use. CRS mode uses the GPS signal to provide the aircraft groundtrack. This mode can
be useful for avoiding restricted airspace, weather and oncoming air traffic.
3. Intercept mode (INT
) – used to intercept a predefined GPS desired track (DTK) as
illustrated below. The INT mode also uses the GPS signal to provide the aircraft
groundtrack. This mode is useful to regain the original flight plan track after
circumnavigating the previously mentioned flight obstacles.
In both the CRS and INT modes the ground track to be followed may be selected by the pilot,
using either the L/R switch or the PCS steering mode of operation
The EZ Pilot will automatically switch from the INT mode to the TRK mode as it nears the
intercept boundary.
