When I posted the short initial comment regarding ADSB-IN / SeaWorld accident (post #43) I hadn’t anticipated the number and wide ranging contributions; so thank you for all your posts.
In my eyes the Sea World and Mangalore accidents are “bellwether” indicators of many of the issues / topics raised in many previous ATSB reports as well as the enormous number of posts on this and other aviation websites over the last 10 years.
I have been sent a copy of a technical paper (apparently available on the internet) that appears to be a production of two ATSB staff that was delivered to the ISASI conference in 2022.I believe it actually won an award for best paper at that conference. The paper under the name “From See and Avoid to Detect and Avoid” seems to be the basis for ATSB’s confidence and reasoning in their somewhat simplistic “marketing” for ADSB-IN for all VFR aircraft and the basis of this thread started by Clinton.
Some of the content also seems to be the source of graphical input in ATSB’s YouTube videos on the Mangalore accident, comparing the ground based TAAATS Eurocat STCA information with a prototyped ADSB-CDTI cockpit display.
An initial read of the paper and a review of the ATSB YouTube videos elicited the following doubts/issues:
1/. ATSB’s understanding of how the TAAATS Eurocat STCA functionality works and displayed is misleading, incorrect and definitely incomplete in the ATSB report and YouTube videos,
2/. ATSB’s ability to conduct proper investigations is severely hindered by their lack of knowledge and understanding of how TAAATS Eurocat works. A contributing factor to this is seemingly the lack of access to lossless video screen capture (TAAATS Eurocat Main/Auxiliary displays) coupled with synchronised air/ground and ground/ground audio. Evidence to be detailed in subsequent posts.
3/. Some of the concepts and graphical prototypes in the paper appear to have similarities in concept to an ADSB-IN cockpit product as described by BRONTË EXPERIMENTAL as per post # 72, as well as TCAS / ACAS general cockpit concepts.
4/. Some comments in the paper relevant to an investigation didn’t seem to be in the ATSB report, I will have to do a forensic examination of both.
