Airspeed Indicator 8030-B.864, 3″, 0-300MPH/0-260 Knots
8030-B864 Airspeed Indicator is designed for use on an aircraft to indicate the speed relative to the air at sea level altitude. This FAA Certified Indicator is then able to indicate the equivalent speed corresponding to the actual force of the air. When properly connected to an airspeed tube, the airspeed indicator measures the differential pressure developed between the pitot and static opening. The 8030-B448 indicates the Range Out pressure in units of the airspeed of 0-260 Kts.
