The following - very recent! - screenshots have been produced and uploaded to this international pooling webpage by our worldwide net of cooperators, using advanced equipment such as the superb PROCITEC Digital Data Decoders. All frequencies are in kHz, and all system times are UTC. Schedules and traffic details can be found in our 2023/2024 Guide to Utility Radio Stations. Standard aeronautical • meteorological • telecommunication abbreviations and ICAO Airport Codes and Airline Designators can be found everywhere; certain very special procedures and terms - particularly for avionics - are explained hereunder. Latest screenshots on top!

• DELAY is a critical procedure, designed to prevent pilots
from acting on any old CPDLC messages

The most serious of such cases would be
the pilot executing a clearance that was no longer valid

• The Altitude Range Change Event is triggered
when the aircraft's altitude exceeds the altitude ceiling
or floor defined in the contract by the ground system
• The Basic or Periodic Report gives position - trajectory intent - speed vector data
plus data for navigational accuracy
• The Waypoint Change Event is triggered by a change
made to the Next, or the Next-plus-one waypoint
This change normally occurs due to normal waypoint sequencing by the FMS
The Next or Next-plus-one waypoint can be either an ATS waypoint or a pilot inserted waypoint
• The Periodic Contract is a report sent every ... minutes
It specifies the reporting rate at which the avionics is required
to assemble and downlink the requested information to the ground system
The minimum reporting rate is usually not greater than every 14 minutes
but can vary to suit the need of the ground station
This procedure allows longitudinal and lateral separation of aircraft
in oceanic areas to be reduced to 30 nautical miles

This procedure allows longitudinal and lateral separation of aircraft
in oceanic areas to be reduced to 30 nautical miles
