Abstract
Systems and methods for operating an avionics component to a level of certification. Steps include: receiving and sending data to a data monitor and an integrity monitor, the data monitor operating at a first level of certification and the integrity monitor operating at a second higher level; using the integrity monitor, determining where a feature of the data should appear on a display; checking if the feature properly appears, and if not, an error condition appears. The system includes: a sensor for sensing an aircraft condition; a data monitor for receiving and rendering data from the sensor, the data monitor certified to a first category level; an integrity monitor for receiving the data from the sensor and for calculating where a feature of the data should appear on a data display, the integrity monitor certified to a second higher level. If the feature does not properly appear, an error condition appears.
