Introduction

1.3 Regulatory Compliance

The MX20 is designed and tested to meet the following TSO/JTSOs when connected to the appropriate
equipment (see Section 3.1.13):
FAA TSO-C63c/JTSO 2C63c
FAA TSO-C110a/JTSO-C110a
FAA TSO-C113/JTSO-C113
FAA TSO-C118/JTSO-C118
FAA TSO-C147
Since FAA TSO-C151a "Terrain Awareness and Warning System (TAWS)" does not include display
requirements, the MX20 does not have TSOA for TSO-C151a. However the MX20 is designed and
tested to be compatible as a display device for the TSO-C151a TAWS sensors listed in Section B.6
Garmin AT has evaluated the MX20 with respect to the guidelines of AC 23-18, Installation of Terrain
Awareness and Warning System (TAWS) Approved for Part 23 Airplanes. The MX20 display is not a
requirement for Class B TAWS installations. The MX20 improves the pilot's situational awareness and
complies with AC 23-18, paragraph 7.h for TAWS displays.
The MX20 software is designed and tested to RTCA/DO-178B, levels C and D, and ED-12B, levels C
and D.
Unauthorized changes or modifications to the MX20 will void the compliance to required
regulatory agencies and authorization for continued equipment usage.
"The conditions and tests required for TSO/JTSO approval of this article are minimum performance
standards. It is the responsibility of those installing this article either on or within a specific type or class of
aircraft to determine that the aircraft installation conditions are within the TSO/JTSO standards. If not
within the TSO standards, the article may be installed only if the applicant documents further evaluation for
an acceptable installation and it is approved by the Administrator. The JTSO article may be installed only if
the installation is performed in accordance with Part 43 or the applicable airworthiness requirements."
