D201 changed alright - when airway B39 was replaced by L18.
B39 ran from DUB - RADNO but L18 is a direct track between DUB and BCN. The Cardigan Bay danger areas were all changed to fit the new airway. All this was in the AIRAC of 16/03/2006
Jabberwok,
You are correct I am sure. The danger area may have changed. But my point is that it has not changed since the current chart was produced. It is correctly displayed on the current chart, and therefore no correction or amendment is necessary to the current chart. So why publish a correction/amendment?
HGFC1,
I find that statement frightening and rather irresponsible to say the least. Why are you not interested? In the (extremely unlikely) event of someone planting a 300' mast on the top of Snowdon, can we expect you to be the first to crash into it?
Well for one thing I don't fly 300' above ground level. It's illegal in the aircraft that I fly. I tend to fly as high as possible in any case.
Secondly, you need to assume that there are obstacles up to at least 800' above ground level. This is because obstacles below 300' AGL are not shown, and elevations change in 500ft. Therefore an undisclosed obstacle can be up to 798' AGL and not be shown on the chart.
Thirdly, I fly with my eyes open, looking for such things.
Fourthly, I did look through the list for any new obstacles of sufficient height that I thought they might cause me concern. I didn't find any, and as such didn't amend them.
Here are a sample of the amendments that I didn't make:
Confirmation of LONDON/City elevation - 19ft amsl
BROOKLANDS - delete all reference and site details at 512103N 0002812W - show as disused aerodrome
SHOBDON elevation changed to 317ft amsl - from 318ft amsl - plus slight amendment to ATZ - from 521430N 0025253W to 521430N 0025252W
Delete multi/unlit obstacle 651(313) at 530903N 0000343W
Amend Multi/Unlit obstacle at 510627N 0010504E from 804(211) to 817(230)
Now if you think I'm going to crash on landing at Shobdon because it dropped by 1ft, or hit an obstacle because it changed elevation by 13ft, or one that has disappeared.....
If fact......there are no new obstacles above 500agl.
Have you even looked at the list of amendments, never mind actually make them?
You of course are free to amend as you wish, but I feel pretty safe with my amendments
