display. Autotilt may be enable continuously as the system always uses the current manual tilt setting as the starting point.
RADAR ANTENNA
The antenna sweep is selectable for either 120 degrees (60 degrees each side of the airplane) or 60 degrees (30 degrees each
side). The antenna tilt is adjusted between -15 degrees (down) and + 15 degrees (up). The antenna maintains its stabilization
with respect to the horizon regardless of the airplane attitude (within -15 to +15 degrees).

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 simultaneously
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 provides
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 accommodated.
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.
Refer to the Rockwell Collins Pro Line 21 Avionics System Challenger 300 Operator’s Guide for a detailed description and
operation of the flight management system. Included in the operator’s guide is their website to obtain the latest performance
database updates from Rockwell Collins Inc.

FLIGHT MANAGEMENT SYSTEM (FMS) (Cont)
COMPONENTS AND OPERATION
DEAD RECKONING (DR)
When no navigation sensor data is available for the FMS to use, it begins navigating in the DR mode. In this mode, it estimates
its position based only on the last known position, heading, and airspeed. To identify this mode, FMS DR is annunciated
on the MFD and on the PFD if the NAV SOURCE is FMS. It also shows on the CDU message line and MESSAGES
page.
FMS CALCULATED VSPEEDS (Optional)
The VSPEEDS function allows the pilot to set or adjust takeoff and approach speeds on the PFD, and show those reference
speeds on the airspeed tape. FMS calculated VSPEEDS are an option on the aircraft.
The pilot can manually set the takeoff and approach reference speeds or adjust FMS calculated Vspeeds on the PFD with
the REFS menu and display control panel (DCP). VSPEEDS are grouped on the REFS menu pages into takeoff speeds and
approach speeds.
The pilot may accept the default or FMS calculated VSPEEDS value, or set a different value. The PFD show the reference
speed as a digital readout on the speed reference table at the bottom of the airspeed tape. It also sets a reference bug for
