GREAT - Thanks Chris - I've been waiting for a thread like this.... our problem is as follows.....
The STCA subsystem only detects conflicts with relative bearings greater than 15 degrees on the horizontal axis, this is incorrect as it should detect them in the full 360 degree range, the types declared in the subsystem interface specifications are correct as degrees are in the range 0 to 359 and the 0 to 360 integer passed into the subsyetm from the multi-radar trackers is converted such that 360 degrees is cast to a 0 value as it should be.
Any ideas?
