ADSB as a SAR tool is reactive, not proactive unless it is mannned 24/7 by an ATCO.
Agreed Frank, however, combined with other existing measures like a SARTIME or flight note, had you gone from A to B and then decided to wander over to C, and had an oops......who would know where to start?
Or even between A and B, once the SAR phase is up and running, they will start looking where first? At the end of the trail??
