Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
Undefined Waypoints
When an identifier is entered on the DATA BASE WPT page and the
FMS cannot find a waypoint in the navigation database with that
identifier, the FMS goes to the PILOT WAYPOINT page for waypoint
definition.
FMS DATABASE
The FMS database consists of two parts: a navigation database and a
custom (or pilot--defined) database. The navigation database is loaded
into the FMS and can not be changed by the pilot. Using the custom
database, the pilot customizes the FMS by defining waypoints and
storing flight plans.
Navigation Database
The FMS retrieves information from the navigation database about
waypoints and procedures used in flight planning and to tune navaids
for position determination. The database, supplied by Honeywell, is
updated every 28 days.
The navigation database is designated with a version number, region
name, and cycle number (e.g., Version 3.01, WORLD3--310). The FMS
uses a Version 3.01 navigation database or other approved version
number. The region name (e.g., WORLD 3, NZ3EAST, NZ3WEST)
varies depending on the content of the navigation database. The last
2 digits indicate the cycle number (e.g., --310). There are 13 cycles
(28 day periods) during the year. Therefore, the last two digits ranges
from 01 to 13. When a cycle has to be modified off cycle, a letter is
appended starting with A. For example, WORLD3--310A indicates a
modified 10th cycle of the navigation database.
The navigation database contains the following:
