altitude Compensated Tilt (aCT)
The Altitude Compensated Tilt feature of the GWX 70 enables the system to automatically
adjust the antenna beam tilt angle setting based on aircraft altitude changes. For example, if
the ACT feature is enabled and the aircraft climbs, the system compensates by adjusting the
tilt downward. As the aircraft descends with ACT enabled, the system adjusts the antenna tilt
upward. The system uses the ground as a reference for adjusting the antenna tilt setting with
ACT enabled.

Typical Tilt Settings by Phase of Flight
Range Setting
20 NM Activate weather mode when clear
of ramp area.
40 - 60 NM If precipitation is observed in the
departure path, gain can be reduced
to aid in identification of intense
returns.
60 - 80 NM Range setting is dependent upon
ground speed and time available for
deviations.
60 - 120 NM Range setting is dependent upon
ground speed and time available for
deviations. Tilt angle set to show
minimal ground clutter.
60 - 120 NM Range setting is dependent upon
ground speed and time available for
deviation.
40 - 60 NM Range setting is dependent upon
ground speed and time available
for deviation. Tilt angle set to show
ground clutter in outer 1/3 of radar
display.
20 NM These settings allow for observation
of the approach area and the missed
approach holding area.
