INTRODUCTION
The Radio Navigation System contains the radios and controls used for navigation purposes. Included in these systems are
Terrain Awareness Warning System (TAWS), transponder, VHF navigation radios, weather radar, radio interface unit
(RIU), displays and controls with FMS, Radio Communication, GPS, and TCAS.
Two separate systems are provided for radio navigation. They are designed and installed so that the failure of one system
does not preclude the operation of the other system. Both are connected to the on-side and cross-side cockpit displays and
controls.
Equipment, controls and wiring are designed and installed so that the operation of any of the system components will not
adversely affect or will not be adversely affected by the simultaneous operation of any other radio or electronic unit
or system.
The Challenger 300 is equipped with conventional navigation systems as follows:
- Integrated Navigation Receivers
- Distance Measuring Equipment
- Automatic Direction Finder
RADIO INTERFACE UNIT (RIU)
The left and right Radio Interface Units are located on their respective equipment racks forward of the entry door.The RIUs
accommodate data concentration, communications and audio management, and control functions. The RIU provides an in-
terface between the radios and the rest of the aircraft systems and equipment. They receive inputs from TAWS and TCAS
and distribute digital audio signals from the audio control panels (ACPs).

  • Page 1 Challenger Global 300 - Navigation INTRODUCTION The Radio Navigation System contains the radios and controls used for navigation purposes. Included in these systems are Terrain Awareness Warning System (TAWS), transponder, VHF navigation radios, weather radar, radio interface unit (RIU), displays and controls with FMS, Radio Communication, GPS, and TCAS.

  • Page 2: Vhf Navigation System

    Challenger Global 300 - Navigation VHF NAVIGATION SYSTEM DESCRIPTION The standard VHF navigation system includes dual VOR/localizer receivers, dual glideslope receivers, dual marker bea- cons, single distance measuring receiver (DME), and single automatic direction finder receiver (ADF). A second ADF and a second DME are available as options.
  • Page 3 Challenger Global 300 - Navigation VHF NAVIGATION SYSTEM (Cont) RADIO TUNING AND OPERATION MFD TUNING The multifunction display (MFD) and display control panel (DCP) provide single point control of both the onside and cross-side radios from the pilot’s and copilot’s position. The radio menu provides a summary of the radios as well as control for each.
  • Page 4 Challenger Global 300 - Navigation VHF NAVIGATION SYSTEM (Cont) TRANSPONDER/TCAS OPERATION The radio menu provides basic transponder and TCAS control. The TRANSPONDER/TCAS CONTROL menu provides control display for other transponder and TCAS operations. The active beacon code, TCAS mode, and TCAS altitude limits selection that show on the left of the TRANSPONDER/TCAS CONTROL menu are identical to the TRANSPONDER/ TCAS display on the radio menu.
  • Page 5 Challenger Global 300 - Navigation VHF NAVIGATION SYSTEM (Cont) TUNING REVERSION Normally, the MFD provides the master tuning control. However, if the MFD fails or is reverted to a compressed PRF for- mat, radio tuning through that MFD is no longer available. Tuning reversion allows the pilot to select either the MFD or the CDU as the master tuning control.
  • Page 6 Challenger Global 300 - Navigation VHF NAVIGATION SYSTEM (Cont) DISTANCE MEASURING EQUIPMENT (DME) The DME-4000 is a remote mounted, three channel unit designed to provide position navigation information, including distance. In the single DME configuration, channel 1 can be tuned by the pilot, channel 2 by the copilot. Channel 3 is used by the FMS.

  • Page 7: Mode S Transponder System

    Challenger Global 300 - Navigation MODE S TRANSPONDER SYSTEM DESCRIPTION The Mode S transponder system consists of two Mode S transponder units. Only one transponder unit is active at any one time, while the other has a standby role. The transponder system supplies ATC, or a traffic alert and collision avoidance system (TCAS) equipped aircraft with aircraft identification and altitude data in response to an interrogation.

  • Page 8: Traffic Alert And Collision Avoidance System (Tcas)

    Challenger Global 300 - Navigation TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) DESCRIPTION The TCAS II system is an airborne traffic alert and collision avoidance system that interrogates transponders in nearby air- craft and uses computer processing to identify and display potential and predicted collision threats. The system protects a volume of airspace around the TCAS equipped aircraft.

  • Page 25 Challenger Global 300 - Navigation TERRAIN AWARENESS WARNING SYSTEM (TAWS) (Cont) MODE 6 — Altitude Callouts (Cont) - The excessive bank angle alert is a function of the roll angle with respect to altitude above ground level. The alert envelope varies linearly from a 10° bank at 30 feet AGL, at 40° of bank at 150 feet AGL, to 55° of bank at 2450 feet AGL.
  • Page 26 Challenger Global 300 - Navigation TERRAIN AWARENESS WARNING SYSTEM (TAWS) (Cont) MODE 7 — Windshear Warning Mode 7 provides alerts and warnings when significant windshear is detected by the TAWS. Mode 7 is active during takeoff and landings phase of flight only, between 10 and 1500 feet AGL. There are two types of windshear warnings: increasing performance (updraft/headwind) and decreasing performance (downdraft/tailwind).

  • Page 27: Terrain Awareness Alerting

    Challenger Global 300 - Navigation TERRAIN AWARENESS WARNING SYSTEM (TAWS) (Cont) TERRAIN AWARENESS ALERTING The terrain alerting function computes minimum terrain clearance envelopes for areas along the flight path of the airplane. The function uses airspeed and flight path angle data in conjunction with a database containing worldwide topographical relief information in grid format.

    Challenger Global 300 - Navigation 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.
  • Page 34 Challenger Global 300 - Navigation 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 esti- mates its position based only on the last known position, heading, and airspeed.
  • Page 35 Challenger Global 300 - Navigation FLIGHT MANAGEMENT SYSTEM (FMS) (Cont) Four or more available satellites allow receiver to autonomously compute the position integrity. The position can be calcu- lated (with the required integrity) on the basis of the 3 satellites data available in addition to an air data altitude. The system permanently performs the receiver autonomous integrity monitoring (RAIM) process, which represents the method of de- tecting and isolating the satellite errors by using the redundant satellite measurements.
