GROUND SCANNING This function enables consultation of the TCAS computer fault recordings as defined by the Component Manufacturer. The TCAS peripheral monitoring and internal cyclic tests are used in order to detect transient faults. (Ref. Fig. 038)
(6)
GROUND REPORT This function is used to present class 1, 2 or 3 internal faults when they are detected on ground. These faults differ from those displayed on the LAST LEG REPORT page. The following figure shows examples of internal faults recorded on ground by the TCAS system. The relevant trouble shooting data are displayed by pressing the line key adjacent to the fault indication. (Ref. Fig. 039)
