INTRODUCTION
The FMS provides flight planning capability and navigation information
to the flight crew. The FMS manages flight details from takeoff to
touchdown. These details encompass standard instrument departures
(SIDs), standard terminal arrival routes (STARs), and instrument
approach procedures (IAP). The FMS provides predictions regarding
estimated time along the entire flight plan.
Legacy Autopilot System Interaction
Many legacy autopilot systems fly the CDI left/right needle without
reference to the To/From indicator.
When flying outbound from a fix for a course reversal and the FMS
sequences to the inbound leg back to the fix (the CDI changes to To),
the autopilot NAV mode will fly the left/right needle with reverse sensing
until the aircraft is turned inbound. To avoid this situation, fly the
outbound using the heading mode.
FMS DATABASE DESCRIPTION
The FMS relies on several database components including the
navigation and custom databases. The navigation database consists
of airport, navigation aid, and waypoint information used by the FMS to
perform navigation functions.
The custom database consists of flight plans and pilot--defined
waypoints. The custom database consists of the following information:
D
Custom (Pilot--Defined) Waypoints -- Custom waypoints can be
defined by position (latitude and longitude) or bearing and range
from a referenced waypoint (referred to as bearing/distance (B/D)).
D
Flight Plans -- Flight plans specify an origin, destination, and route
of flight. The memory allocated for flight plans is full when reaching
either the maximum permitted number of flight plans or the total
permissible number of flight plan waypoints being used in the flight
plans.
