In a single-WXP installation, radar range is controlled with the DCP located on the
same side of the cockpit as the WXP, providing transfer mode is not selected (XFR
button on the DCP).

Weather Radar Displays
Pushing the WX button on the DCP adds the weather radar overlay to the following
MFD formats:
• NAV SECTOR
• FMS MAP
• TCAS
Figure 17-14 shows an example of the weather radar overlay on the supported MFD
formats.
Weather radar system and/or lightning detection system failure messages are displayed
on the weather radar mode line, or in the lower left and right corners of the MFDs.

Display Levels
The colors used on the radar display to represent rainfall intensity are as follows:
Path Attenuation Correction (PAC) Alert Mode
When a precipitation cell is of sufficient dimension to use the full range of attenuation
correction, a condition known as Path Attenuation Correction (PAC) alert occurs. Its
function is to allow a true image of a precipitation cell to be rendered by making
allowances for the radar beam’s absorption as it penetrates the precipitation cell. The
PAC alert puts into view those areas which absorb the radar beam.
The heading to these areas is shown by a yellow arc at the edge of the radar display.
All precipitation in the sector between the displayed weather targets and the yellow
PAC alert arc may be incorrect and should be avoided.

Weather Radar Display Modes
Refer to the “Collins Pro Line 4 Avionics System for the Challenger 604” Pilot’s
Guide for additional operational information on the weather radar system.
Test Mode
Selecting TEST mode initiates the weather radar RTA functional self-test. The TEST
mode ensures that the MFDs are capable of processing and displaying the weather data
represented by various colors. Six colored arcs show on the MFD in TEST. The fifth
arc changes between red and magenta on alternate sweeps.
The transmitter is disabled in TEST mode, but antenna scan and tilt functions remain
operational.

THE AREA WITHIN THE SCAN ARC AND WITHIN TWO FEET

CONSTITUTES A HAZARDOUS AREA. DO NOT OPERATE
THE SYSTEM IN ANY MODE OTHER THAN TEST WHEN THE
ANTENNA MIGHT SCAN OVER PERSONNEL. DO NOT
