If that is so why would you persevere with an obvioulsy faulty unit that clearly is purely a distraction. If I were you I would send it back and have it replaced under warranty or check to see if there were issues caused by the aircrafts you are operating - you have read the manual that came with it, have you?
I don't get to choose what's put in the aircraft. I get assigned, I fly it. It's that simple. And yes, I've read the manual. It's on this computer, in fact.
downrange of the UK at night VFR - I doubt that very much.
What you believe or doubt is very much irrelevant.
It's also very much night VFR here, no matter what the conditions. We're somewhat southeast of you.
True. Maybe that is SNS3Guppy's problem - low batteries or iffy power - anything is possible I suppose if you try hard enough.
I certainly don't try to make the unit fail, and it's hardwired into the aircraft power. Batteries are not an issue.
The PCAS is better than nothing, but just barely...and where it may lead one to distraction, it may be worse than nothing in some cases.
I was going by your profile.
I'm international. Always have been.
