Danger Areas, please explain?

[MedusaThrills]

All latitudes in the UK are 50-something or other (except for the islands to the very far north of Scotland which are 60's).

Therefore, simply take the first digit of the Dange Area code and that will tell you what latitude it lies to the north of.

D117 - North of 51 degrees North
D307 - North of 53 degrees North

You will note that some cross the line of latitude, e.g. D203 (mid Wales) originates north of 51 degrees North but the majority lies to the north of 52 degrees North, hence the '2' designator. Similarly, D308 lies in the majority to the north of 53 degrees North with a portion to the south of the latitude.

The next two digits are simply numerical idenitifiers and have no geographical relevance.

D703/15 lies to the north of 57 degrees north, is Danger Area No.03 and extends to 15,000' AMSL.

I am a bit confused still.
With the
"D117 - North of 51 degrees North
D307 - North of 53 degrees North"

How do you know it is north? You also say the next two digits (marked in bold) are simple numerical identifers and have no geographical value. What is the point of this then? Would appreciate if you expanded on this. Sorry for being a newbie Dont ask, dont learn

So for example;
D307 / 12 - This would be 53 degrees North, ........ and extends to 12000ft AMSL ?

edit: I saw you wrote that the numerical value (07 in above example) is the danger area number. What is this? Are there certain different degrees of dangers in the UK?
