The difficulty I guess is deciding where the cutoff point is. In my opinion if you are going to fly with passengers in IFR conditions then you need the safety and redundancy of the minimum equpment stipulated by the CAA. There is no similar tolerance for equipment failiure as there is in VFR daylight flight.
Personally I stopped flying at night (other than IFR, on a flight plan in an airway, in a turbine or twin) after I suffered an engine failiure at night in a piston single on a flight as an instructor. To much risk for me!!! Prior to that I had the "it will never happen to me attitude"
It is nice to get home if the weather is poor - but at what risk?
The LAA do a fantastic job with what they look after, is a move towards permit IFR aircraft just going to stretch things a little to far from the whole ethos that they operate in?
