Indicating panel of combined indicator instrument for flight or sea navigation

摘要

The indicator panel consists of two co-axial discs (1,6) rotating independently of each other. One disc is a very high frequency omni-directional radio range indicator VOR (1) and a compass disc (6). The totally visible disc is the VOR disc is the VOR disc (1). The rear compass disc (6) can only be seen through an opening (3) in the VOR disc. The VOR indicator is driven by a VOR receiver of the aircraft. The VOR disc has a pointer (2) reaching from its centre point to its edge, which bridges the opening (3) forming two halves. The pointer positions itself according to the respective flight situation to a setting between 0 and 360 deg. and represents the actual line of position (L)P). The hexagon (fig 3) in pointer source or indicating panel centre point represents the controlled VOR transmitter. The compass disc lying under the VOR disc has a parallel arrow group, which are aligned continuously in the course direction. The arrows are only visible in the part appearing in the opening (3).
