BITE Test of the Weather Radar

TASK 34-41-00-740-002-A
BITE Test of the Weather Radar

WARNING: OBEY THESE SAFETY PRECAUTIONS WHEN THE WEATHER RADAR IS IN OPERATION. MAKE SURE THAT:

ALL PERSONS ARE MORE THAN 5 METERS (16.4 FT) AWAY FROM THE ANTENNA.
NO PERSON IS IN THE AREA MADE BY AN ARC OF 135 DEG. ON EACH SIDE OF THE AIRCRAFT CENTERLINE.
THERE IS A MINIMUM SAFETY DISTANCE OF 60 METERS (200FT) BETWEEN THE ANTENNA AND ALL REFUELING OPERATIONS.
THERE IS A MINIMUM SAFETY DISTANCE OF 5 METERS (16.4 FT) BETWEEN THE AIRCRAFT AND ANY OBSTACLE IN THE AREA MADE BY AN ARC OF 90 DEG. ON EACH SIDE OF THE AIRCRAFT CENTERLINE.

THE AIRCRAFT MUST NOT BE IN A HANGAR OR IN A CLOSED AREA.

WARNING: MAKE SURE THAT:

THERE ARE NO PERSONS OR OBSTACLES IN THE RADOME AREA.
THE CAPT AND F/O DISPLAY SELECTOR SWITCHES ON THE WEATHER RADAR CONTROL UNIT ARE SET TO OFF (THIS PREVENTS SYSTEM EMISSIONS ON THE GROUND).

NOTE: If the avionics ventilation is incorrect, the radar images are not shown to prevent overheat of the NDs.
