FLIGHT MANAGEMENT SYSTEM (FMS)
DESCRIPTION
The Rockwell Collins FMS-5000 Flight Management System single or dual FMS is a fully integrated navigation and flight
management system designed to provide the pilot with the following features:
- En-route, terminal, and Non-Precision Approach Lateral and Vertical Navigation with automatic transition to the
Precision Approach.
- Flight plan management.
- Multi sensor navigation.
- Maps and text data display.
- Performance management.
The system is integrated with a GPS receiver which processes the transmissions from multiple GPS satellites simultaneous-
ly to calculate navigation solutions based on information from all satellites available. A minimum of four satellites with
acceptable geometry, or three satellites plus calibrated barometric altitude are required in order to calculate a navigation
solution. The computed GPS position, velocity and time are inputs to the FMS, which integrates this data into the flight
plan based navigation solution. AHRS, ADC, DME, and VOR systems also supply data for use by the FMS. The FMS pro-
vides necessary controls for all input sensors, when appropriate, via the control display unit (CDU).
When a single FMS system is installed, it is operated via the CDU installed on the right side of the center pedestal. When
two FMS systems are installed, each CDU controls its on-side FMS.
The FMS can be initialized, waypoints and destination selected by a variety of means. SID, STAR, and airways are accom-
modated. A great circle route is calculated between waypoints for enroute lateral navigation (LNAV), and roll steering is
provided to the flight control system (FCS). A sophisticated interface with the FCS allows the FMS vertical navigation
(VNAV) function to select various FCS vertical modes of navigation. This sophisticated VNAV interface is often referred
to as coupled VNAV. The VNAV and LNAV capability can be advisory only, if the FMS is not coupled. The FMS provides
vertical steering when required by the FCS.
FMS interfaces with the EFIS displays to provide conventional navigation information, state-of-the art map presentation,
performance and optional Vspeed data.
