Process and device for aiding aerial navigation, with display of navigation instruments used

摘要

A process and device for assisting aerial navigation. The system affords the pilot of the aircraft greater knowledge regarding the situation which results from automatic decisions of a flight management system. A central zone is displayed on a viewing screen which represents the overall use of the navigation instruments. Peripheral zones of the screen represent the individual instruments with a visible plot of the relationship between the central zone and a particular peripheral zone when the latter corresponds to a navigation instrument actually being used. For example, the central zone is a disk whose diameter represents the mean error in position given by the use of the various instruments and the visible plots of relationship are color radial sectors which extend between the central zone and certain peripheral zones. The names of the instruments are indicated in the peripheral zones.
