Danger Areas, please explain?
Hello, Vems;
As I understand it, your example can be split into five sections
D: shows it is a danger area as opposed to restricted or prohibited
7: shows that north of 57° there be dragons - the only digit that applies to the latitude
03: is the danger area descriptor - in case there are other danger areas at this latitude (this is an assumption on my part...)
/: shows that you are about to get a limit
15: in this case means sfc-15000' amsl
Once again, as I understand it, it is merely to give you an indication, so if your GPS says that you are at N56°59'59.99" you *should* be safe.
This will, of course, mean you don't have to explain those 7.62mm mothholes in the canvas...
Look in the AIP ENR5.1 for them all and it should become clear when you have examined a few examples.
Regards,
Patrick
