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. This information is
updated every 28 days. The database can also store up to 200 pilot-
defined flight plans and waypoints, which are only updated when
changed by the pilot.
In single configuration, the Data Loader (DL) is used to update the
Database, transferring data to and from the Navigation Computer. In
this configuration, this unit can be installed on the left lateral console,
close to the pilot’s mask stowage box.
In dual configuration, the Portable Data Transfer Unit (PDTU) is used
to reload entire information package at each update by using a 3

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.
