|PITOT SHIELDS are a “fail-safe” pitot tube cover that will protect the pitot tube from contamination by insects, debris and ice while the airplane is on the ground. It is friction-fit to the pitot tube and has a calibrated “flat-plate-forward” design that, upon reaching a specific velocity, will release from the pitot tube and fall harmlessly away, allowing for normal airspeed indications. The cover utilizes EVA foam that is UV resistant and stable at temperatures reached by heated pitot tubes. It is a highly visible color with the words “REMOVE BEFORE FLIGHT” printed and visible from all directions. This pitot tube cover is soft, but tough. It will not damage aircraft surfaces when it comes off during ground roll, nor will it be a potentially hazardous foreign-object on the runway.|
This is the perfect pitot tube when my aircraft is in my hangar. But now I have lost two that have blown away in the wind when sitting on a transient ramp while outdoors.
This photograph is very misleading. This model (10-00493) is for a Piper Blade type of pitot system, not a tube type. It therefore didnt work for my Piper PA-30
