All the above - I DO apologise for diverting this thread. I was merely trying to highlight the fact that a 'climb to IMC at 2400ft' was not a very practical way to look at continuing to Inverness given a/c endurance, icing clearance, duty time, available aids and the like - and no, I'm not suggesting it would be better to carry on 'regardless' IMC at 500ft before someone suggests that - just that a low-level VFR transit was the ONLY solution to the task with that equipment.
