1.3.1.1 Installation Approval of Version 1 ADS-B Systems
GTX 330 w/ES transponders running software versions v6.00 through v6.20 support Version 1 ADS-B
Out functionality. According to AIR-130 Policy Memo 'Approval for ADS-B Out Systems', dated August
30, 2010, the FAA has suspended field approvals of Version 2 ADS-B Out equipment. At the time of this
publication, there is currently no FAA policy addressing field approvals of Version 0 or Version 1 systems.

There are three options for installers wanting to install GTX 330 w/ES transponders with software versions
6.00 through 6.20:
1. Installers may elect to disable the ADS-B Extended Squitter function, as described in
5.2.17.
2. Installers may utilize a Supplemental Type Certificate (STC) for the GTX 330 with the Version 1
ADS-B Extended Squitter activated.
3. Installers may obtain a field approval with the Version 1 ADS-B Extended Squitter activated.

showing compliance to the AMC requirements. This data together with Form 337 may be used for
approval by the appropriate FSDO inspector.
