an engagement switch (push-button type) and
two potentiometers labeled ROLL DRIFT and
PITCH DRIFT. The sonar operator has control
of the ASE when the CPLR mode is on, and the
cyclic coupler switch is in the CABLE ANGLE
position. The sonar operator may engage and
control the transducer cable angle by trimming
the helicopter's pitch and roll attitude. This
lets the operator maintain the cable angle
perpendicular, relative to the horizon.

The four ON-OFF toggle switches are PITCH,
ROLL, COLL, and YAW. These switches let the
pilot disengage any of the four channels of the
ASE. Normally, the switches are left in the ON
position. They are positioned to OFF to disengage
a malfunctioning channel. The four guarded
switches are for maintenance personnel to
introduce HARDOVER signals to the individual
channels when they test or troubleshoot the ASE.
NOTE: The channel monitor test switch on
the pilot's compartment dome light panel MUST
be in the test position before using the HARD-
