OK just tried a new scenario, this time November 1944 with a Type XXI boat. I started snorkeling from periscope depth in the North Sea in the middle of the night, I was unmolested by aircraft for the entire night. This was in wind speed 6 seas, I'm not sure how well you could run the snorkel in higher wind speeds though. I found in calm sea you can still make the snorkel work from 17 m depth, it just skims the surface.
Clearly the first time they were eyeballing me. BTW I should say I'm using the airpower mod, so I don't know if the radar is still faulty in the Wellington.
Well with this change and if the radar detectors can be set to historical limits it would seem that the survivability issues can be much improved. Let me know if you need any more info for the radar detectors Jungman
