All the high-tech flight instruments wont help much if the basic pitot-static system contains inherent errors. Read the story to learn how to find them.
Most owners of amateur-built aircraft are interested in knowing how well their airplanes perform, and airspeed is an important parameter in all types of aircraft performance measurement. But aircraft pitot-static systems have many possible sources of error that may affect indicated airspeed and altitude. Thus, before using your indicated airspeeds to determine performance, it would be wise to determine what the error is in the airspeed indication system.
