Abstract

Instrument de mesure d'angles constitué d'une plaque transparente rectangulaire sur laquelle sont tracées des graduations permettant d'évaluer des angles et des longueurs et de faire tout tracé ou report sur un support tel qu'un papier à dessin ou une carte géographique destinée à la navigation aérienne ou maritime et comportant une plaque transparente pouvant pivoter à frottement doux par rapport à la plaque principale de l'instrument. Cet instrument est caractérisé en ce que la plaque transparente est pourvue sur sa face inférieure tournée vers la plaque principale de l'instrument d'une cavité dans laquelle est og une aiguillé permettant d'afficher les corrections à effectuer sur le cap à tenir.
