The irony is that EASA are slowly moving towards permitting commercial single-engine operations in IMC after about 15 years of campaigning by the likes of the Cessna Caravan and Pilatus PC XII crowd. There will be caveats of course, but it will at last allow commercial ops by say 2016/17 I think in a Cessna Caravan wizzing around the UK which ought to be cheaper than our hideously expensive trains per pax if you fill the seats.
