1. WEATHER RADAR SYSTEM
The weather radar system provides the flight crew with X--band color display of radar
detectable precipitation and ground mapping along the aircraft’s flight path. System range is
up to 320 nautical miles and up to 60 degrees on either side of the aircraft’s flight path. The
weather radar control panel provides control of the following:
S System modes -- Weather, ground map and hold
S Receiver gain control (±18 dB) and gain calibration
S Antenna azimuth scan angle (either ±60_ or ±30_)
S Antenna elevation control (±15_) in either automatic tilt or manual tilt (0.25_
increments)
S Antenna pitch and roll stabilization.
The display control panel is used to select the weather radar format on the multifunctional
displays (MFDs). The weather radar data can also be overlaid in navaid sector, present
position map and TCAS modes.
Split scan operation enables both pilots to control the radar display on their respective
MFDs. Each side will operate independently, except that either pilot can control the sector
scan of both displays. In split scan operation, the clockwise sweep of the antenna updates
the pilot’s display and the counterclockwise sweep updates the copilot”s display. If one side
is turned off, the system reverts to single scan operation. <0028>
