Under the auspices of the CAA Electronic Conspicuity Working Group (ECWG), in July 2017 FASVIG published a document to the ECWG entitled “FASVIG GA Airfield Pseudo Radar Trial” outlining a proposed trial of low-cost Automatic Dependent Surveillance Broadcast (ADS-B) traffic display technology by GA airfields ATS units. This was endorsed by the CAA in a public statement on 16th August 2017.
Now, under the new Airspace4All banner, we propose to run the GA Airfield ADS-B Traffic Display Trial during a six month window commencing in 2018 (subject to CAA permission).
The aim of the trial is to gather evidence to enable the CAA to assess this capability and give consideration to policy change authorising use of ADS-B real-time traffic displays by GA ATS units. Additionally, it is hoped this trial will encourage further development of technology to support ATS provision at UK GA airfields.
For the duration of the trial the ATS Units at three GA airfields will be equipped with real-time flight tracking equipment that provides a situational awareness tool (which is not to be used to provide any form of Air Traffic Control service).
The proposed Trial Airfields are:
• City Airport Manchester Barton (Barton)
• Chichester/Goodwood Aerodrome (Goodwood)
• Gloucestershire Airport (Gloucester)
Additionally, to complement those aircraft already equipped with ADS-B Out, a number of general aviation aircraft based at the Trial Airfields will be equipped with CAP1391-compliant ADS-B Out devices. Airborne ADS-B capabilities of the CAP1391 compliant devices are outside the scope of the trial.
The data transmitted by General Aviation aircraft during the trial is not assured, and has been treated as such in the safety assessment.
