2-1/4" and 3-1/8" airspeeds are supplied and marked in MPH and knots scales. Indicators feature 360 degrees sweep for easy reading at a glance. All Winter Airspeeds come complete with mounting screws.
Airspeed-indicators measure the difference between total pressure and static pressure.
The total (or measured) pressure is sensed by a pitot tube positioned at the stagnation point of the airstream and is carried to the airspeed indicator by a hose. A static pressure sensor can also be connected. The measuring element is an open diaphragm unit with excellent elastic properties; hysteresis (differences between advance and return movement) and secondary elastic effects are negligible. The effect total pressure and static pressure acts on the diaphragm, causing a deformation, that is transferred to the pointer by a linkage and gear mechanism. The different operating ranges of the aircraft can be identified by color markings on the airspeed indicator dial. The instruments are insensitive to shock and vibration.
