SPZ--8000 Digital Integrated Flight Control System
5 SECT (Sector Scan) Button
Pushing the SECT button toggles between full azimuth (120_) or sector
scan (60_). In sector scan the display is updated more often since the
antenna sweeps a shorter arc than in full azimuth mode.
6 TILT Knob
The TILT knob selects the tilt angle of the antenna beam relative to the
horizon. Cw rotation tilts the beam upward to +15_ and ccw rotation tilts
the beam downward to --15_. The most used range (--5 to +5 of tilt)
is expanded for ease of operation.
A digital readout of tilt is displayed on the EFIS or MFD.
PULL AUTO Function -- When the TILT control knob is pulled out,
D
the system is in automatic tilt mode. In this mode, the antenna tilt is
automatically adjusted according to selected range and barometric
altitude. The antenna tilt automatically readjusts with changes in
altitude and/or selected range. In automatic tilt, the tilt control can
fine tune the auto tilt setting by 2_.
Auto tilt is annunciated by adding A to the digital tilt readout on the
EFIS or MFD. The digital tilt readout always shows the commanded
tilt of the antenna regardless of the tilt command source (automatic
or manual tilt).
1. TO AVOID FLYING UNDER OR OVER STORMS, FREQUENTLY
SELECT MANUAL TILT TO SCAN BOTH ABOVE AND BELOW
THE AIRCRAFT'S FLIGHT LEVEL.
2. ALWAYS USE MANUAL TILT FOR WEATHER ANALYSIS.
Stabilization -- The radar is normally attitude stabilized. It
D
automatically compensates for roll and pitch maneuvers. Attitude
stabilization can be disengaged by pushing the TGT button four
times within three seconds. (It is re--engaged in the same way.)
