(Cont)
production delivery of the helicopter and pertinent
corrections to the electronic section of the pre-
liminary handbook of maintenance instructions.
(2) Description of the composite electronic system
including antenna placements with a discussion of
the design parameters and considerations which
influenced the installation.
(3) Conformance test data which will provide evidence
that electronic demonstrations were performed
with representative equipments.
(4) A graphical presentation of the intercommunication
system (ICS) audio power output analysis, covering
the range of audio interphone control facilities
available to the crew, including frequency response
measurements, to show acceptable quality of audio
response in the system
(5) Interference survey of the composite electrical and
electronic systems with specific Interference sources
indicated and a discussion of corrective measures
taken. Procedures shall be in accordance with
Spec MIL-I-6051.

5422 or in an environment where the air pressure,
air flows, air friction, temperature, humidity, etc.,
duplicate conditions at the service ceiling of the
helicopter.
(8) Preliminary antenna radiation patterns. These
radiation patterns shall be made in flight for all
applicable antennas, with proper allowances made
for cable losses and all significant propagation
factors to assure repeatability and determination
of absolute values of signal level.
