ADS-B Mandate – ATCs Responsible for Deaths?
I believe that approval needs to be sought ( by the airline or the crew) and granted before operating the flight.
I'm wondering if the outbound crew even knew about the condition of the equipment (if it was brought to their attention), seeing as it was inconsequential to the inbound crew who continued operating above F280 when either the equipment failed, or it was realized that it wasn't working ... that is to say, perhaps it was only within range of Australian equipment it became apparent it was not working
