A challenge to those who write your NOTAM parsing algorithms:

The current PJE NOTAM at Little Rosborough defines a coned exclusion area, with a different effective area depending upon your altitude. This appears to be quite common with PJE NOTAMs. Any chance you could display the radius effective at your planned altitude, rather than that for FL120?

If parsing is too difficult, the ability to plot a circle centred at a given point and at a specified radius would be almost as good.
