TSO-C145a 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
2. The ability to mitigate the effects of the different gain characteristics of those
3. The ability to further increase the effective mask angle, through operational
4. The ability to use -128 dBmic as the minimum GPS satellite signal-in-space for the
5. The ability to use -128 dBmic as the minimum SBAS satellite signal-in-space for
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.
ETSO-C145 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

TSO-C151b 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.
ETSO-C151a 1. Garmin was granted a deviation from ETSO-C151a to use DO-160E instead of DO-
160D.
