Rotate counterclockwise – from the CAL position decreases gain in WX, WX+T
and MAP modes.
There is no EFIS indication for CAL gain because CAL gain is the standard gain
setting. The EFIS will display "VAR" when gain is moved above or below the
CAL gain position.
During automatic operation, the MultiScan radar provides Gain PLUS, which
includes: (Refer to Section 11.20 for expanded description)
• conventional increase and decrease of receiver sensitivity
• the weather radar automatically increasing gain as outside air
temperature decreases
• Path Attenuation Compensation (PAC) Alert
• Oceanic Weather Reflectivity Compensation
• OverFlight Protection
• Predictive OverFlight (With WX+T selected)
• Associated Threat Function (With WX+T selected)
• Core Threat Adjustment (With WX+T selected)
• Two-Level Turbulence Detection (With WX+T selected)
• Flight Path/Descent Assessment

TILT Control
During Automatic mode operation, the TILT controls are not active.
When AUTO is selected, an A shows on the EFIS by the tilt angle. When
operating in Manual mode M shows.
Rotate clockwise – radar antenna tilts up to selected degrees from horizon.
Rotate counterclockwise – radar antenna tilts down to selected degrees from
horizon.
Note: When the WXR system is first powered up (either through initial airplane
power, WXR circuit breaker closure or following an extended power
interrupt) the indicated tilt will temporarily show the manual tilt setting or
zero Auto “0A”. This is a normal condition while the system goes through
initial power up built in test (PBIT) and determines the appropriate tilt
angle based on current location, altitude and flight path.
