D216 shown as a Restricted area to FL150

(1/1)

Phil King:
Jeff,  I've just installed v5.7 and on the plot of airspace and notams I see D216 Credenhill (near Hereford) as a restricted area up to FL150.  I am unaware that this is a restricted area.  I suspect that it may be that the new feature to display danger area details in a pop-up may be misbehaving.  Please can you have a look and see whether I've misunderstood something?

Thanks Phil King

jeff:
No, it's nothing to do with code - it's data.

I took the Croft Brown airspace from here (Tim Newport-Peace format) and adapted it for Spine. It needed adapting because CB set all danger areas to TYPE=PROHIBITED, which I changed back to TYPE=DANGER. Otherwise there would be solid red splodges all over the map.

As for D216, I see it appears twice with different top alt and slightly different coordinates in different parts of the file:

Croft Brown original

--- Code: ---#  Dated 20 Mar 03  ENR 5-1-3-11
INCLUDE=YES
TYPE=PROHIBITED
TITLE=D216:CREDENHILL
BASE=SFC
TOPS=2300ALT
CIRCLE RADIUS=2.00 CENTRE=N520453 W0024806

#
INCLUDE=YES
TYPE=RESTRICTED
TITLE=D216 CREDENHILL
BASE=SFC
TOPS=FL150
CIRCLE RADIUS=2.00 CENTRE=N520449 W0024759

--- End code ---

My changes just involved changing the PROHIBITED to DANGER. I didn't notice the duplication.

I don't have an up to date chart (retired from gliding), so perhaps you could post what the chart actually says this should be (with the correct coordinates.

jeff:
More on this. I have contacted Croft Brown and he agrees there are errors, specifically with the duplication of D216. He will be issuing an amended update shortly.

Phil King:
Thanks Jeff for investigating this.

By the way the update for v5.7 apparently installed on my Windows XP system without any problems.  I didn't need to re-install from scratch.

jeff:
A new version of Spine is in the pipeline and revised airspace will be included with this.

Edit: V5.8 has the revised airspace.
