I have often set out searching with an empty mission so to speak, I place the sub in an area and patrol to see what turns up.
I have hit on a lone merchant and on the odd occasion got a convoy, which like Jim said is a bit more realistic, and I like that.
But sometimes I get attack after attack by aircraft and still no DD comes looking, I expect because there isn't any in the area but I thought may be it spawned one after a certain amount of time.

I just had a thought while I was typing, in SH2 if you shot down the aircraft then the spawn link was destroyed (I think). I wonder if this is the case in SH3?
I may alter an aircraft not to fire any ammo, have it as a spot plane and see if the desired effect works.
