3.0 INSTALLATION PROCEDURES
3.1. Planning
Careful planning for the install of the AirCell
®
ST 3100 system will ensure an efficient installation with
minimum down time for the aircraft and will ensure optimal system performance and easy maintenance
access in the future. Study the aircraft for optimal antenna location, plan equipment locations with service
in mind, and select the proper cabling before ordering. The Customer will be pleased to get the aircraft
back in service promptly as the result of your planning.
Refer to Aircraft manufacturing guidelines and/or to FAA AC 43.13-1B and -2A. FAA AC 43.13-1B
(Acceptable Methods, Techniques, and Practices) Chapter 11, and FAA AC 43.13-2A (Acceptable
Techniques, and Practices-Aircraft Alterations) Chapters 2 and 3 provide excellent guidelines to ensure a
good installation.
A field-approved FAA Form 337 that references a STC as a basis for a follow-on field approval,
references to acceptable approvable data and/or DER documentation (Form 8110-3) approving
installation data, is the usual required documentation path for the installation of this system.
Note
ST 3100 part number 400-01680-001 has a Plain Old Telephone System (POTS) interface and the 400-
10680-002 has no POTS interface. These transceivers are identical including revision levels; the only
exception is the -002 configuration lacks a POTS module installed on the motherboard.
Note
Requirements of the applicable FARs may stipulate that proper DER engineering documents
(Form 8110-3) be supplied or that the installation be performed in accordance with an acceptable STC.
3.2. Equipment Location
If this is a new installation of an AirCell
®
ST 3100 system, you will need to comply with the installation
instructions of this manual, FARs, and FCC requirements by selecting RF cabling to satisfy the approved
requirements of the system. Keep the cable attenuation as low as possible in the cable run from the ST
3100 Transceiver to the Satellite Antenna, as the performance of the system will be greatly affected by
this cable attenuation.
Mount the Transceiver where rain or harsh environments will not be present. Refer to System
Specifications, Section 7.0, for further details regarding the environment requirements, as the AirCell
®
ST
3100 Transceiver is not weather proof. Avoid a completely “sealed” chamber, as ambient air movement
is required to cool the AirCell
®
ST 3100 Transceiver. When considering the use of ram-air for cooling,
ensure that rainwater will not be ingested and sprayed onto the equipment. Cooling can extend the Mean
Time Between Failure (MTBF) of electronic equipment located in a tightly packed avionics bay, so a fan
may be a worthwhile consideration.
