Posting on this site as I get the impression more of you have these on your
side of 'the pond'

Have any of you incorported any form of moiture trap in your plumbing?
Today I was flying in cloud and lost my ASI after climbing around 1000
metres, presumably through water getting into the tubes. The thought that
the water might also get into the sensor unit onto the electronics and
cause the horizon to fail caused me some concern which I'd rather not
repeat!
