Thank you. We have found the problem that was preventing the airways around ELLX from being hidden as they should have been, since they are entirely within the bounds of other controlled airspace.

EHAM is more difficult. I had a look at it, and all the airways I looked at definitely protrude outside of the blocks of class A airspace. Could you give a few examples of airways shown around EHAM which should be hidden?

Hello,

Around ELLX it is:

M150

Z110

Q763

which are all embedded in General C airspace (the airways are all C).

Btw. Belgian airspace is the same story and the chart around Amsterdam (EHAM) is, actually, not really usable. Again, these airways are all embedded in airspace of the same class.

Could you please address this issue?

Thank you.

Which airways? What altitude?

Hello,

We only show those airways if their lateral limits protrude outside of the other class A controlled airspace, in other words, if there is a need to be aware of them. On more than one occasion it has been discovered that we were showing class A airspace that the CAA/NATS chart was not, which was their error.

For the UK, SD charts in VFR mode show airways where the base of the airway is at the same altitude/level as other airspace of the same class, whereas the UK CAA half million VFR charts do not show those airways. An example is airway L10 over Milton Keynes in Bedfordshire where both the airway and the London TMA have a base of 5,500 ft. I would find it more helpful if the SD charts looked more similar to the CAA VFR charts. What is the reason for the different approach?

Problem solved!

Maps updated.

I really appreciate the fast response.

Thank you very much.

The official source for airspace data is the Danish AIP, not a chart. I'm going to email you so we can get this resolved once and for all.

Hi Tim,

Why don't you just remove the airways so your map looks like the official Danish map?

While we are at your map I have earlier pointed out (sent an email) that your map is missing a couple of class C TMA-areas north of Copenhagen.

Here they are framed by thick lines:

We have re-enabled hiding of airways by grouping them with controlled airspace in the next version.

However I do not believe that will solve this specific problem, which is that many Danish airways poke out of the TMA as defined in the AIP. Unless we are misreading the AIP, that is.
