Also buried deep in the consultation document is the idea that these ModeS Transponder units they are mandating we fit WILL ONLY BE CERTIFIED FOR VMC USE.
Maybe I've read it incorrectly, but I presume this will mean NO MORE of the following:
Gliding in wave / climbing to the top of a thermal ie within 1000' of cloud (ie IMC) / no more flying on an even slightly hazy day. Am not sure of the effects on IMC flight / night flight.
Yes there's the cost issue, but surely THIS is an even more important issue that could stop virtually all recreational non-powered flying as we know it?
