This sounds like a good case for waiting for a couple of years before I install the mode S kit. I still can't understand how mode S is going to be useful until all flying vehicles have it. And, what advantages are there if I can't get a service from ATC or see other other aircraft?
In a couple of years time without Mode S you won't be able even to leave these shores for a spot of European Touring.
We took the 'head in the sand' approach with Mode S only a few years ago and installed a mode A/C replacement when our ancient TXPDR went t*ts up. Mode S seemed so far away and so expensive then...........
So now we'll be dumping a pretty new (in aviation terms) Mode A/C Garmin in favour of mode S.
All this Filsher cr*p has certainly steered me back towards Garmin..............
