My SMS notifying system is now well under testing, and working quite OK.
Here is an example from today.

Airpics FW Radar Alert!
Afriqiyah Airways (Adria Airways) Airbus A320-231 (S5-AAB c/n 113 Flight ADR3411) is now 2.64km away on an altitude of 250 ft, descending -704 ft / min. It flies a heading of 71 degrees, and 128 knots. Probably approaching runway 07.
What I now want to do is to inform where the aircraft is located relative to the airport.
North, East, South, West, Southeast and so on.
I have the coordinates of the airport which is:
Latitude: 63.111944
Longitude: 7.82611
Example of an aircraft coordinate:
Latitude: 63.0778
Longitude: 7.7217
I've been searching for an easy way to determine this so I can write this in the messages, and also maybe use it in the calculations when finding out if an aircraft is approaching the runway.
