Abstract

L'invention concerne les instruments indicateurs. Elle se rapporte à un instrument qui comprend une fenêtre Il portant des échelles 15 et deux rubans 19 et 20, le ruban 19 comprenant une partie transparente 24 et une partie opaque colorée 23, séparées par une limite 25 dont la position par rapport à l'échelle 15 indique l'amplitude d'un premier paramètre. La seconde bande 20 a une limite 31 entre deux parties 28, 29 de couleurs différentes, représentant un second paramètre, et une partie 30 du ruban 20 peut être cachee ou découverte par la partie 23 du premier ruban et indique une relation entre les deux paramètres. Application aux instruments indicateurs de roulement au sol des aeronefs.
