if you know a 'vrp' that is current so marked on the chart but is actually difficult to spot / recognise from the air, (eg perhaps it was a disused airfield that is now completely built on, or that sort of thing) - can you e-mail CAA DAP about it please to dave dot drake at caa dot co dot uk - cheers.
If you happen to know any feature that isn't a VRP but is no longer 'viable' as what the chart says it is, that's a different thing - there is a contact on the chart itself - so for example, Zeals disused airfield was never a VRP but in recent years it was no longer recognisable as a disused airfield (unless you happen to take a very close look at the white 'tower like' house there and realise it is an old military tower - so someone finally told the chart people, at it's gone as a disused airfield on the new charts.
