I've read through the CAA document (on the train on the way home) and I am a bit worried that if they change to ICAO style Rule 5 option then we will not be able to descend below 500' under any circumstances, whereas we can now theoretically descend to any height ("depth"!?) as long as we are not "within 500' of any person, vessel, vehicle or structure".
When doing PFLs, it is good to be able to take the training scenario much lower than 500' in my view as it helps student to really appreciate whether they would "make the field" and see the picture (including wires!?!) from low level. When done a good safe distance from anyone or anything (i.e > 500'), then I think this is safe.
I'm interested to hear what others think about this particular aspect of the proposed changes. At first glance, I think we should oppose this possibility.
Otherwise, I suppose it makes sense to rationalise the complex existing rules (less work for lawyers

) but I'm not sure that this needs to be high on the CAA's list of priorities... is the existing wording
really causing much difficulty?
