A 100ft cloud base is below the minima for most ILSs.
True. But if my enroute IMC flight section would exactly there, the rest would be an approach in helicopter VMC
But according to what I've learned today on pprune.org (an invaluable source of knowledge)
this won't work for die EASA E-IR, as there normally won't be controlled airspace (for IFR) that low.
Had the UK guys an IMCr(H) + Austrian VMC rules, they might be able to leaglly land with cloud base at 100AGL (way below ILS minima) as they are flying IMC VFR, not the EASA en-route
IFR.
Please don't go flying around in IMC until you are a) properly trained, b) properly licenced and c) in a properly equipped helicopter. Otherwise, you might well end up as a statistic of the worse kind.
No worries, I'm way too intimidated by the shear thought of an SPL darting through clouds on his way to the other valley to find some thermals.
