Table 1-14. GIA 63W TSO/ETSO Deviations
1. Garmin was granted a deviation from TSO-C92c to use DO-160E instead of DO-160C.
2. Garmin was granted a deviation from TSO-C92c to not include the version and levels of software
or the modification status of hardware in the appliance number.
1. Garmin was granted a deviation from ETSO-C92c to use DO-160E instead of DO-160D.
1. Garmin was granted a deviation from TSO-C145a to use DO-160E instead of DO-160D.
2. Garmin was granted a deviation from RTCA/DO-229C paragraphs 2.1.1.10, 2.1.1.7,
2.1.1.8.1, 2.1.1.8.2, 2.1.1.9, 2.1.2.1, 2.1.3.1, 2.1.4.1.4, 2.1.4.1.5 and 2.1.5.1 in the form of an
operational limitation to achieve an equivalent level of safety. This operational limitation applies to
the GIA63W with GPS software version 2.40 or earlier, or GIA63W installations with certain models
of GPS/WAAS antennas identified in Section 2.1.3.2. The operational limitation is based on:
1. The ability to use antennas that may not meet the minimum gain performance requirements of
DO-228.
2. The ability to mitigate the effects of the different gain characteristics of those antennas by
increasing the effective mask angle through operational limitations.
3. The ability to further increase the effective mask angle, through operational limitations, to a level
commensurate with test conditions used in the original TSO qualification tests.
4. The ability to use -128 dBmic as the minimum GPS satellite signal-in-space for the purpose of
assessing the operational limitation.
5. The ability to use -128 dBmic as the minimum SBAS satellite signal-in-space for the purpose of
assessing the operational limitation.
3. Garmin was granted a deviation from RTCA/DO-229C paragraph 2.1.1.9 to use a 20 second
satellite reacquisition time instead of a 10-second reacquisition time.
1. Garmin was granted a deviation from ETSO-C145 to use DO-160E instead of DO-160D
2. Garmin was granted a deviation from ETSO-C145 to use DO-229C instead of DO-229A
3. Garmin was granted a deviation from DO-229C paragraphs 2.1.1.10, 2.1.1.7, 2.1.1.8.1,
2.1.1.8.2, 2.1.1.9, 2.1.2.1, 2.1.3.1, 2.1.4.1.4, 2.1.4.1.5 and 2.1.5.1 in the form of an operational

assessing the operational limitation.
4. Garmin was granted a deviation from RTCA/DO-229C paragraph 2.1.1.9 to use a 20 second
satellite reacquisition time instead of a 10-second reacquisition time.
1. Garmin was granted a deviation from TSO-C151b to use DO-160E instead of DO-160D.
2. Garmin was granted a deviation from TSO-C151b 4.a. to mark the unit with the serial number
instead of the date of manufacture.
1. Garmin was granted a deviation from ETSO-C151a to use DO-160E instead of DO-160D.
1. Garmin was granted a deviation from ETSO-C151b to use DO-160E instead of DO-160D.
