I think the easiest way to proceed would be to use the FGNetFDM (--native)
protocol or the --generic protocol (which allows you to design custom
packets with the specific fields you choose.) Both of these can send the
data out as UDP packets which then can be read by your external program
using standard socket communication.
This same basic mechanism also would permit your external program to send
control commands so if some day you want to do some sort of hardware or
software in the loop testing of your uav controller, that is also a
possibility.
