Automated oceanic position reports via Automatic Dependent Surveillance - Contract (ADS-C)
Over half of the airliners making North Atlantic oceanic crossings are equipped today with Automatic Dependent Surveillance - Contract (ADS-C) equipment that delivers automatic position reports. As a result you may notice a lower level of use of the High Frequency (HF) radios. It should be much easier for you to contact the radio operators to deliver your voice position reports and requests as fewer pilots are talking to them.
