FLIGHT PLANNING
The flight planning function computes the active flight plan with both
lateral and vertical definition.
When the FMS long-range navigation is selected, the flight director
command bars will provide the visual command to bank the airplane to
the desired track.
The VNAV is applicable only for the descent path and it is not coupled
to the flight director, being only a reference information displayed on
the PFD glide slope scale.
Additionally the navigation computer can be programmed by the
operator to automatically fly different types of holding patterns.
DATA BASE
The database contains worldwide coverage of navaids, airways,
departure procedures, approach procedures, Standard Terminal
Arrival Routes (STARs), airports and runways. The database can also
store up to 200 pilot-defined flight plans and waypoints, which are only
updated when changed by the pilot.
The database must be updated every 28 days through a 3 ½" floppy or
ZIP disk inserted in the Data Transfer Unit (DTU).
NAVIGATION DISPLAY
A multiple waypoints map, based on the airplane's present position,
can be displayed on the MFD. It comprises the Waypoints connected
by white lines defining a pre-planned route, and also navaids and
airports.
