True Airspeed Indicator (3-1/8")
CONFIGURATIONS: 180, 200, 250, 300 or 400 MPH. This popular 3-inch airspeed indicator is perfect for new installations or as a retrofit for older, outdated indicators. Specific range markings and dial configurations can be added to correspond with each individual aircraft. The 8100 series provides true airspeed indication by turning the knob and setting the outside air temperature in the TAS window.
