True Airspeed: Operates on same principles as other airspeed indicators. This model has an adjustable outside air temperature setting which allows the user to compute the True Airspeed. See website for up to date pricing.
This airspeed contains an altimeter diaphragm and temperature diaphragm which continually modify the magnifying ratio of the airspeed mechanism. The effects of density and temperature changes are continuously counteracted, thereby providing constant true airspeed. This indicator has a capillary tube with a temperature bulb that must be mounted through the fuselage. Dials available in MPH, Knots, or Dual Scale MPH outer-Knots inner or Knots outer-MPH inner.
