The studies described here are an extension of the earlier ones and have been aimed at examining the problem in UK airspace, which differs from that of the USA in that there are far fewer aircraft of the general aviation class. The present study aims also to categorise aircraft on the basis of the SSR Mode A identity code indicating the probable class of aircraft, whether civilian transport, military or private. In due course the precise mechanisms for the generation of the errors will be identified but for the present it must be accepted that such errors may arise anywhere from the altitude encoder to the transponder, not ignoring the possibility that the cable connections and the plugs and sockets in particular are highly suspect. A small piece of metal swarf could short the pins together or to ground and in the event of the transponder being removed for repair the fault will be apparently rectified.
