Change in Aviation: ENVIRONMENT | FANS & CNS/ATM

1 Nov 10	Eurocontrol publishes newsletter on ADS-B progress

10 Feb 09	Australia sets compliance date at December 2013 for ADS-B above FL290

This might help! The developments in the future of air navigation systems (FANS) are divided into CNS/ATM - Communications, Navigation, Surveillance and Air Traffic Management. Communications covers how ATC 'talks' to aircraft. In the old days, this was morse code, then voice over VHF and HF Radio - today many centres are moving towards CPDLC (Datalink communication) Navigation is the method used to determine position and to find direction. Traditional: Dead Reckoning, Radio beacons (NDB/VOR), and later INS and IRS with Radio updates. Developing: GPS/GNSS added, and regulated by requirements in RNP (Required Navigation Performance) - a term being replaced by PBN (Performance Based Navigation) Surveillance is how ATC receives that position - traditionally radar, but increasingly ADS-B/C, and Multilateration. ATM in this instance refers to the changes in how Air Traffic Control facilities operate internally, and interact with each other. In Europe, the Single European Sky Initiative is an example of ATM development. *OUR FOCUS* here is how these changes affect you as an Aircraft Operator, or Pilot. Updates will appear above, and the documents below are intended as useful background reading on the changes.

Report on the operational trial of Waypoint Reporting (FMC WPR)
Current - Issued Mar08 Published by the ISPACG
In October 2007 Airways New Zealand and Air New Zealand commenced an operational trial of Waypoint Reporting (FMC WPR) in the Auckland Oceanic FIR. A number of airlines routinely receive ACARS position reports from their aircraft via satellite as part of their Airline Operational Control (AOC) flight monitoring. These position reports can be forwarded to an ATS provider and used to replace HF voice position reports. This method of delivery for aircraft position reports is known as Flight Management Computer Way Point Reporting (FMC WPR)
