Abstract
13. In a vertical air speed responsive instrument, the combination of a chamber enclosing a substantial volume of air a constricted passage connecting said chamber with the atmosphere a differential pressure responsive member connected to respond to a difference in pressure inside said chamber and the atmosphere, respectively a movable member connected to be actuated by said pressure responsive member and an element responsive both to variations in pressure and temperature of the air inside said chamber and connected to increase and decrease the resistance of said passage to a flow of air therethrough upon a rise in pressure and drop in temperature, and a drop in pressure and rise in temperature, respectively, whereby said member will be moved in true response to a vertical air speed, irrespective of changes in altitude and viscosity of the air.
