Rob,
I put two of these static traps in the
IV. Even though the airplane has flown through heavy rain and spent a few nights
outside in hard blowing rain, I ain’t never seen nuthin in ‘em. I believe
that if your lines exit the static ports upward for several inches you’ll
decrease the possibility of water accumulation by a great deal.
In the 320 I put no traps, just exited
the ports upward and never had any water in 2300 hrs. If you are going to use a
trap, I’m sure that anything you can come up with will work as well as the
commercial trap. If you do use a trap, put it as close to the static port as
practical. The amount of water you will catch, if any, will be measured by the
milliliter, not by the gallon.
Most commercial pitot tubes have a built in drain so it should not be
necessary in the pitot system.
