SPZ--8000 Digital Integrated Flight Control System
9 RADAR Mode Select Switch
The following paragraphs explain the switch positions for the RADAR
mode select switch:
OFF -- For a single controller installation, this mode turns the
D
controller functionally off. Electrical power is not switched off until
the avionics bus is turned off. For dual controller installations, both
mode switches must be selected to OFF before the system is turned
off.
SBY (Standby) -- In the standby mode the antenna scan is
D
positioned at +15_, scan stops, the transmitter is inhibited, memory
is erased, tilt and stabilization remain active. When the switch is in
this position, STBY is displayed in the mode field.
NOTE: Provisions are included in the weather radar controller to
force the system into forced standby when there is
weight--on--wheels (WOW). Forced standby can be
overridden by pushing the range buttons simultaneously.
ON or WX (Weather) -- The ON (WX) mode selects basic weather
D
operation. Auto or variable gains can be used. Precipitation levels
are displayed in five colors: level 0 (black), level 1 (green), level 2
(yellow), level 3 (red), and level 4 (magenta). When the switch is
in this position WX is displayed in the mode field.
GMAP (Ground Mapping) -- The GMAP position puts the radar in
D
the ground mapping mode. The system is fully operational and
GMAP is displayed in the mode field.
As a constant reminder that GMAP is selected, the alphanumerics
are changed to
yellow, and magenta.
yellow is a moderate return, and
If GMAP is selected before the initial RTA warmup period is
complete, WAIT is displayed in the mode field. In wait mode, the
transmitter and antenna scan are inhibited and the memory is
erased. When the warmup period is complete, the system
automatically switches to the ground mapping mode.
1. THE SYSTEM PERFORMS ONLY THE FUNCTIONS OF
WEATHER DETECTION OR GROUND MAPPING. IT IS NOT
INTENDED THAT THE SYSTEM BE USED OR RELIED ON FOR
PROXIMITY WARNING OR ANTICOLLISION PROTECTION.
2. WEATHER--TYPE TARGETS ARE NOT CALIBRATED WHEN
THE RADAR IS IN THE GMAP MODE. DO NOT USE THE GMAP
MODE FOR WEATHER DETECTION.
