and it would be good if the VFR route was amended to avoid D342
?
The VFR route is where it is for good reason: ease of navigation, off built up areas, and beaches to potentially land on in the event of engine failure.
Move it out to sea and you have aircraft at low level over water with all the safety issues that entails. Move it inland and there will be environmental issues with noise and mixing with EN<>MB traffic.
I'm surprised no ones mentioned as well the the drop zone isn't marked on VTCs
No-one has mentioned it because it
is on the charts as a Danger Area with symbol (since either June or November last year).
