CHAPTER 1. OPERATING LIMITATIONS
1-1. General
NOTE
The use of this device does not alter the
published aircraft limitations in any way.
Refer to Section 1 of the basic Rotorcraft
Flight Manual.
1. The Powerline Detection System is designed for
either 50 Hz or 60 Hz power lines. The aircraft must be
equipped with the appropriate system for the power lines in
its operational area.
2. The Powerline Detection System will not warn
against lines, wires or strike hazards that do not emit an
electric field at a power line frequency. Some examples are:
a. Guy wires.
b. Telecommunications cables.
c. Direct Current (DC) power lines.
d. Unenergized power lines.
e. 50 Hz power lines if equipped with a 60 Hz detector.
f. 60 Hz power lines if equipped with a 50 Hz detector.
3. Due to static electrical build up on the aircraft, the
system may be unreliable at dew points below 0°C (32°F)
and should not be relied upon.
1-2. Marking and Placard
1. The following placard is required to be installed in
the aircraft, adjacent to the Powerline Detection System:
WARNING: THE PDS IS A PILOT AID ONLY
AND SHOULD NOT BE RELIED UPON AS A
SOLE MEANS OF AVOIDING POWER LINES

pilot aid.
2. The pilot should continue to use all other power
line avoidance procedures.
2-2. Preflight
1. Check the antenna condition and security.
2-3. Prior to Engine Start
1. With electrical power applied to the aircraft, and
the avionics master switch ON, a small green light mounted
on the Powerline Detector will illuminate to indicate that
electrical power is applied to the unit.
2. Rotate the SENS control CW to maximum.
3. Place the PDS TEST switch on the instrument
panel to TEST.
4. The audio warning will activate. The visual warning
light will activate on the front panel of the Powerline
Detector.
5. Push the WARN/MUTE annunciator switch on the
Powerline Detector to activate the mute function disabling
the audio warning.
6. The yellow mute light will activate. Reset the mute
by pushing the annunciator switch a second time and the
