1.launched a unit (MPH/KPH/KNOTS) switchable airspeed indicator, in order to simplify manufacturing spécification and stocking range; 2.Accurate reading within low airspeed range, evenly allocated scale on the rest of the scale 3.* Zéro adjustable: just one button, the zéro error introduced by weather and dynamic-static system pressure différence can be eliminated; 4.* Error correctable: the airspeed adjustment function can eliminate errors introduced by the location, aging orlimited efficiency of pilot tube. The adjustment is within ±30% of the reading, from 0.7 to 1.3. The errors from airspeed system of plane are then removed. Apart from airspeed scale, the scale for correction coefficient can be found on the dial, atthe bottom edge;
