1 DECLARATION OF DESIGN AND PERFORMANCE
1.1 Introduction
The Declaration of Design and Performance section contains the definition and statement of compliance of
the GSB 15. The section is written in accordance with European Aviation Safety Agency (EASA)
Commission Regulation (EU) No 748/2012 date 3 August 2012.
The full manual is intended to provide mechanical and electrical information for use in the planning and
design of an installation of the GSB 15 into an aircraft. This manual is not a substitute for an approved
airframe-specific maintenance manual, installation design drawing, or complete installation data package.
Attempting to install equipment by reference to this manual alone and without first planning or designing
an installation specific to your aircraft may compromise your safety and it is not recommended. The
content of this manual assumes use by competent and qualified avionics engineering personnel and/or
avionics installation specialist using standard maintenance practices in accordance with Title 14 of the
Code of Federal Regulation and other relevant accepted practices. This manual is not intended for use by
individuals who do not possess the competencies and abilities set forth above.
NOTE
Garmin recommends installation of the GSB 15 by a Garmin-authorized installer. To the
extent allowable by law, Garmin will not be liable for damages resulting from improper or
negligent installation of the GSB 15. For questions, please contact Garmin Aviation
Product Support at 1-888-606-5482.
NOTE
Except where specifically noted, references to GSB 15 apply equally to all GSB 15
variants.

1.2.4Mod Level History
The following tables identify hardware modification (Mod) Levels for the GSB 15. Mod Levels are listed
with the associated service bulletin number, service bulletin date, and the purpose of the modification. The
table is current at the time of publication of this manual (see date on front cover) and is subject to change
without notice. Authorized Garmin Sales and Service Centers are encouraged to access the most up-todate bulletin and advisory information on the Garmin Dealer Resource web site at www.garmin.com
The GSB 15 has been shown to meet compliance with the claimed TSO(s) when interfaced with the equipment defined in this installation manual, and installed in
accordance with the requirements and limitations as defined in this installation manual.
The installer must verify that non-Garmin devices to be interfaced meet the installation requirements identified in this manual to assure the installed system will
comply with the Garmin TSO Authorization. Garmin installation requirements will usually specify that the interfaced device has appropriate TSO authorization, and
in some cases, such as for TSO-C144 antennas, may also require that the non-Garmin device meet additional Garmin specifications.
The conditions and tests required for TSO approval of this article are minimum performance standards. Those installing this article either on or within a specific type
or class of aircraft must determine that the aircraft installation conditions are within the TSO standards which include any accepted integrated non-TSO functions.
TSO articles and any accepted integrated non-TSO function(s) must have separate approval for installation in an aircraft. The article may be installed only according
to 14 CFR part 43 or the applicable airworthiness requirements.
In accordance with the Bilateral Oversight Board, Decision 006, for the Agreement Between the United States of America and the European Union on Cooperation
in the Regulation of Civil Aviation Safety, the FAA TSO authorization makes this an approved article within the respective EASA system. This article was tested to
additional standards (see section 1.3.4) that may demonstrate additional airworthiness specification performance standards required by the European Aviation Safety
Agency (EASA).
The Appliance Project Identifier (API) for the GSB 15 is GMN-02201. The API has been used for project identification with the FAA.
