You can't individually switch off ADS-B-Out on the 787 or any model. If you mean they are switching off the entire Transponder, I can't imagine they are really doing that

Is it possible that the receiver currently covering Wrocław is far enough away that it can't "see" the signal when the aircraft is below 2000m due to the horizon? At 2000m altitude I think the receiver would be about 100nmi away.
|Quoting 3MilesToWRO (Reply 3):|
No way this can be the reason unless 787 has some very strange radio antenna. Every other airplane can be traced to the very gate of EPWR. Besides, I've seen the same behaviour over Bydgoszcz.
|Quoting BravoOne (Reply 4):|
I don't believe the 787-8 in it's current configuration is equipped with ADS-B. ADS-C, yes, but the ADS B will not be available until sometime after the -9 is in service.
|Quoting shiny (Reply 15):|
Airborne ADS-B-In is currently not offered by most manufacturers due to implementation and definition still in progress.
TCAS II is a totally different story and has (almost) nothing to do with ADS-B-In (for those who mentioned it).
