Portsmouth
I am a regular low level transitee of the area around the Spinnaker Tower and have always used the 250,000 chart. I happened to glance at a 500,000 chart the other day and note a restricted(?) area close to Spinnaker up to 2,200feet which certainly doesn't feature on the 250,000. It may well have been there for years. Anyone know what it is for; why it's not on the 250.000; and is blissful ignorance a good excuse?
