"a small inline fuel filter to try and prevent any moisture or insects" You can call me cautious Clara if you like, but I see a small problem with the design of a system which uses a fiber filtration product with the hope that it might trap moisture. Moisture and dust will create mud which does

my filters (one in static line and one in pitot line) are just behind my instruments and should never see moisture. The filters don't effect calibration, tried and proven for many years our club gliders. We change them every year, at a few of dollars each, no problems. I've never seen any evid

Mark seems to have a plan for getting his ASI calibrated and for getting the pitot-static system ironed out, but for anyone who wants to fiddle with actual calibration of their airspeed indicator (on the ground, not using GPS or timed distances), there is a fairly simple method using plastic tub

I couldn't agree more with this statement. We recently went through this with our club gliders. Someone thought that it was a good idea to use low pressure air to blow the water out of the static systems, not! Static lines were blow apart in several difficult to impossible to get to places in t

"We use a nice bright color to help remind people to remove the tape prior to flying." As an old military mechanic we used to place tape over the pitot and static system during aircraft washes. As the plane was turned over to the mechanic for wash, the status of the plane was changed to grou
