From what I understand, it’s fully compliant SIL=3 and seen by everyone – but not sure how I can confirm this.
If this is installed in a European registered, certified aircraft, then compliance will be against CS-STAN CS-SC005A and it will be a configuration 2 device, so SIL-1.
For configuration 2:
The following conditions apply to configuration 2:
— The transponder equipment and its installation are compliant with CS-SC002c or later amendments, or are otherwise approved.
— The ADS-B transmit unit (transponder) is approved in accordance with ETSO-C166b, or later revisions, or the equivalent.
— The GNSS receiver is approved as a class B ETSO-C199 TABS device.
— The transponder is configured to use a class B ETSO-C199 GNSS position source. The GNSS receiver is configured as a class B ETSO-C199 TABS device (SIL=1), which is not compliant with any of the ETSOs defined in configuration 1 for the GNSS receiver.
— The compatibility of the combination of the transponder and the GNSS receiver is explicitly stated by the manufacturer of the transponder.
— The quality indicators are configured to report the quality indicators defined in ETSO-C199 (e.g. SDA=1 and SIL=1) in accordance with the instructions provided by the equipment manufacturer.
