Switching power supply ground plane cuts (again)

No, Joerge doesn't do avionics, mainly medical electronics. Sounds more like your crew should 'silence' him... 8-)

I have been asked to do a long term consulting contract at $WeDoAvionics to teach the engineers how to Do It Right [tm]. The separate plane concept has so many advocates who don't know s*it about actually doing a successful high speed board.

You are so right ;)

The last av project was quite a while ago but I'd really like to know where those split ground systems were installed. So I could make sure not to fly with those aircraft, at least not through thunderstorm zones. Especially in these days of glass cockpits a brief bright lighting up of the instrument panel followed by total darkness could become slightly inconvenient.

Understandable.

Yes, but those troubles bring food onto the table at our house ;-)

Ok, I am too old for service now so I guess I'll be safe then ....

Joerg!

I can not reveal that, but rest assured it will not exist on certain newer aircraft ;)

Seriously - in some instances (particularly low speed highly sensitive systems) a split ground plane can actually be a good thing, but in a mixed signal system it's asking for trouble.

FWIW, the issues are currently on military aircraft - but it seems the opposition aircraftd are worse than ours ;)
