Good to see the double standard still exists, the 787 has been banned from ADS-B airspace overseas as it transmits the wrong position information passing a waypoint
Who on earth told you that? Whose 787s and what 'ADSB airspace'? All the routes I fly where ADSB is mandatory have no problems with the 787, including Oceanic routes. ADSB transmits your position, speed etc continuously and not just when you pass a waypoint. I think you've been fed a kipper
