WEATHER RADAR SYSTEM

 

Description

The Collins WXR–854 is a solid-state, low-power, X-band weather radar system. The radar detects wet precipitation and precipitation-related turbulence along the flight path of the aircraft. A ground mapping function is incorporated to assist with navigation. In addition, a target alert function (TGT) allows the radar to automatically search for heavy rainfall returns and provide an alert to the pilot.
An optional lightning detection system may be installed, and is presented on the weather radar displays.
The weather and map information can be overlaid on ROSE and PPOS navigation formats of either or both PFDs and MFDs.
Receiver Transmitter Antenna (RTA)
The receiver transmitter antenna is an integrated unit with a 14-inch flat-plate antenna. The radar scan is ±60 degrees of the aircraft heading, and the selectable antenna tilt angle is ±15 degrees above and below the horizontal.
The RTA is powered by DC bus 1.

Weather Radar Controls

Weather radar controls are provided by the DCPs. These controls are:
.
Radar menu (RDR MENU) pushbutton

.
RADAR pushbutton

.
RANGE/TILT/PUSH AUTO TILT button

Each pilot and copilot PFD/MFD radar display is controlled by the on-side DCP, and is updated on alternate sweeps of the antenna. With two DCPs, the radar operates as two independent systems.

Overlay Controls

A dedicated multiple press TR/WX pushbutton is provided on both the DCP and CCP, to allow direct access to the list of radar and lightning overlays for display on the PFD/MFD navigation formats. The first press of the TR/WX pushbutton selects the next overlay available on the PFD. A subsequent press selects the next overlay available within the menu.
