Pitot Static System…Airspeed Calculation

Tue, 19 Jul 2016 23:14:22 +0000

Pitot Static System…Airspeed Calculation A. Airspeed Calculation: Airspeed is calculated as a function of the difference between Pitot Pressure and Static Pressure as follows: Calculated or Indicated airspeed is indicated airspeed corrected for instrument errors, position error (due to incorrect pressure at the static port) and installation errors. Calibrated airspeed values less than the … Continue reading

Airspeeds – Get to Know the Operation and Manufactures

Tue, 29 Dec 2015 19:06:56 +0000

Airspeeds – Get to Know the Operation and Manufactures How it works Pitot pressure is forced into the diaphragm causing it to expand like a balloon. Static pressure is contained within the indicator case and surrounding the diaphragm. As the static pressure changes it, will either cause the diaphragm to compress, as the aircraft … Continue reading
