FANS note for today:

To all pilots, the answer to whether you need to report position manually when using FANS over the North Atlantic is "no". FAA and the NAT will use ADS-C position reports in the FANS airspace. See this extract from the FAA NOTAM:

"Position Reports
Position reports should be made via ADS. The two types of ADS contracts that will be established with each aircraft are a twenty (20) minute Periodic Report Rate and a five (5) mile Lateral Deviation Event. This is
in addition to normal waypoint reports. Operators should not use CPDLC for position reports but it should be used for all other ATC communications. Position reports should be made via HF if ADS is not available.
KZWY cannot accept CPDLC position reports containing latitude and longitude in the ARINC 424 format (e.g. 4050N)
