TILT KNOB
The rotary TILT knob is used to set the tilt angle of the antenna beam
with relation to the aircrafts longitudinal axis. Clockwise (cw) rotation
tilts the beam upward to +15
_
; counterclockwise (ccw) rotation tilts the
beam downward to --15
_
.
A digital readout of the antenna tilt angle is displayed on the MFD.
WARNING
TO AVOID FLYING UNDER OR OVER STORMS, FREQUENTLY SE-
LECT MANUAL TILT TO SCAN BOTH ABOVE AND BELOW THE
AIRCRAFT’S FLIGHT LEVEL. ALWAYS USE MANUAL TILT FOR
WEATHER ANALYSIS.
