96.6.18 Gyro Directional Indicator
The gyro directional indicator is a self contained
unit which displays aircraft heading using an
internal directional gyro. A heading adjust knob,
located at the lower left corner of the indicator,
allows for adjustment of a heading bug to a
desired heading.
96.6.19 Operational Check – Gyro
Directional Indicator
96.6.19.1
Apply electrical power to helicopter
electrical system.
96.6.19.2
Close CRS IND PILOT circuit
breaker. Verify that gyro begins to spin up and
warning flag is out of view in less than 3 minutes.
96.6.19.3
Rotate the heading knob and verify
the heading bug will rotate the full 360

of the
indicator.
96.6.19.4
Open CRS IND PILOT circuit
breaker. Verify that warning flag comes into view.
96.6.19.5
Close CRS IND PILOT circuit
breaker.
96.6.19.6
Turn electric power off.
96.6.20 DC Torque Indicator
NOTE
S/Ns 30576, 30687, 30931, 30817
and 30599 use an AC Torque
Indicator indicating system. See
section 96.5 for details. For all
S/Ns except 30576, 30687, 30931,
30817 and 30599 refer to this
section for details of the DC
Torque Indicating system.
96.6.20.1
The DC torque indicator system is a
remote type indicating system. DC power is
routed through a circuit breaker to the torque
indicator which supplies an excitation voltage to
the transmitter. Any pressure sensed by the
torque transmitter will be indicated on the torque
indicator. The copilot torque indicator is
independent of the pilot’s system but functions in
the same manner. The indicator reads in Percent
of maximum torque and also has a digital display
which displays percent of maximum torque. The
digital display will flash when a potential or actual
over-torque occurs and the unit will store this
information in its non-volatile memory.
96.6.21 Operational Check and
Calibration – DC Torque Indicator
96.6.21.1
Any time a transmitter is removed or
replaced for any reason an operational check
should be performed to verify proper calibration.
SPECIAL TEST EQUIPMENT
TYPE OR MODEL NOMENCLATURE
Barfield Type Pressure Tester 0 –
2311F-S or Equivalent 150 psi (0 – 1034 KPa)
96.6.21.2
The torque indicator must be
aligned to the engine installed in accordance with
the torque pressure setting on the engine data
plate.
96.6.21.3
Alignment is accomplished by the
following procedure:
96.6.21.3.1
Open the circuit breaker supplying
power to the associated torque indicator. Remove
the indicator from the instrument panel and
disconnect the electrical connector from the back
of the instrument.
96.6.21.3.2
Connect the calibration stick p/n
10012-033 in line between the indicator and the
electrical connector removed in the previous step.
96.6.21.3.3
Remove pressure line from the
torque pressure transmitter being tested and
attach dead weight pressure tester (Figure 96-5)
to the transmitter.
96.6.21.3.4
Set the pressure on the dead
weight tester to 0.2 x P (Calibration point 1)
NOTE
P =

Close the circuit breaker opened
in step 96.6.21.3.1. indicator will display “CA” for
