Abstract
Abstract An operation supervision system for airplanes with a plurality of measuring feelers, which comprises means for transforming the measuring values into the form of electrical output signals. Indication devices are coordinated to and are operable by the electrical output signals. Norming members follow the measuring feelers. A multiplex sender is operatively connected with the norming members, and senses cyclically the measuring values normed to standard signals and fed to an analog to digital converter. A multiplex receiver is connected with the output of the analog to digital converter by means of a transmission conduit, and quasi-analog electroluminescent display means are provided to which the multiplex receiver divides the measuring values.
