You could also affect other systems such as TCAS"
Underfire,
I don't particularly care what Airservices says, TCAS is TCAS, and is not affected by any ADS-B system.
For years, there has been a standard to incorporate ADS-B IN data in TCAS processing, but as far as I am aware, NO major TCAS manufacturer has incorporated the standard, because it provided NO new functionality, there has been no customer demand.
This is a separate issue to ADS-B/C data for ATC use.
Remember, we are talking TCAS here, not other sundry proprietary collision warning/avoidance systems.
DO 260/260A/260B has got nothing to do with TCAS.
The only way "ADS-B" could affect TCAS is by turning the whole sodding 1090ES transponder off., or some internal fault achieving the same end result.
Tootle pip!!
