0.5, 1,2,5,10 and 20NM) mapping of targets in a sea clutter environment.
Search 2 is designed for precision ground mapping with very high resolution
of short ranges (ie 20NM or less). Search 3 is designed for maximum clutter
returns as required for mapping of oil slicks. On long ranges (beyond 20NM),
Search 1 and Search 2 are similar to Search 3.
Weather Avoidance Modes (Wx and WxA)
By means of a radar echo displayed on the EFIS, the system can furnish
continuous enroute weather information relative to rain cloud formation, rain
fall rate, thunderstorms with moisture, and areas of icing conditions. Digital
circuitry provides a means for determining the relative density of the rainfall
areas. With the EFIS display the pilot can see storm areas in his flight path
and can also distinguish corridors of relative calm through the storms. The
system detects the strong returns from high density rainfall and converts
them into red areas on the EFIS display. If the pilot changes the mode to
the weather alert (WxA) mode and the red area is beyond the range displayed,
the TGT ALRT will flash.
Beacon Mode
In the beacon mode, the system can interrogate and receive pulses from a
fixed transponder(s) located within a range up to 160 NM. The coded replies
are received on a special beacon frequency (9310 MHz). The radar indicator
displays beacon returns from both 2-pulse and DO-172 6 pulse transponders,
located in range and bearing with respect to the aircraft.
The beacon mode can be operated alone, or combined with either the weather
or search modes.
