Goodwood Flying School has been granted permission today by the CAA to use CAP1391-approved ADS-B transceivers in their Piper Cub and Cessna 172 fleet. This permission allows the aircraft to broadcast from the ADS-B transceiver while also transmitting from the aircraft’s Mode S transponders. Simultaneous transmission by the same aircraft via Mode S and CAP1391 ADS-B transceivers is currently restricted under CAP1391 so this permission enables the Goodwood aircraft to contribute to the CAA’s ‘Mode S/CAP1391 Simultaneous Transmission Trial’.

The ADS-B position information that will be broadcast by the Goodwood Flying School fleet will provide air-to-air and air-to-ground electronic conspicuity for the aircraft, enabling enhanced traffic situational awareness for pilots in the air and for the Goodwood FISOs in the tower at Goodwood Aerodrome, delivering a significant boost to GA safety.

This real-time ADS-B aircraft position data will contribute to the Airspace4All GA Airfield ATS ADS-B Traffic Display Trial which is gearing up to go live shortly at Goodwood with the support of Goodwood ATS. Under existing CAA regulations GA airfields without a very expensive radar system plus ATS staff authorised to use radar are not permitted to use ADS-B Traffic Displays. The Airspace4All Trial is gathering 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.

The Airspace4All Trial is already live at City Airport (Manchester Barton). Goodwood Aerodrome in West Sussex and North Weald Airfield in Essex are the other two airfields participating in the Airspace4All Trial and are expecting to go live soon.

Although not part of the Airspace4All Trial, should they choose to do so, pilots flying the Goodwood aircraft will be able to avail themselves of the ADS-B ‘In’ traffic information capabilities of the SkyEcho transceivers (when paired with a suitable navigation device). The devices also allow pilots to receive the real-time weather data currently being broadcast from Goodwood as part of a separate trial being run by Skydemon and uAvionix.
