-LAST LEG REPORT (Ref. Fig. 019) This report contains the fault messages related to the external or internal failures (class 1 and 2) recorded during the last flight leg. The following tables give the list of the failure messages which can be reported and indicate the failure class assigned to them as defined by the CFDIU standard.

NOTE : Failure of one radio altimeter is a class 3 failure whereas it
____ becomes a class 1 failure when two radio altimeters are faulty.
-PREVIOUS LEGS REPORT (Ref. Fig. 019) This report contains the fault messages related to the external or internal failures (class 1 and 2) recorded during the previous 63 flight legs.
-LRU IDENTIFICATION (Ref. Fig. 019) Allows to display the P/N, the S/N and the SW/N of the equipment.
-GND SCANNING (Ref. Fig. 020) Based on the monitoring and fault analysis during flight, provides information of the failures detected while using this function. The WR/PWS peripheral monitoring and internal cycle tests are used to detect transient failures.

The peripheral monitoring and WR/PWS internal cyclic tests are used to detect transient failures.
-TROUBLE SHOOTING DATA (Ref. Fig. 020) Provides correlation parameters and snapshot data concerning the failure displayed in the LAST LEG REPORT and PREVIOUS LEGS REPORT.
-CLASS 3 FAULTS (Ref. Fig. 021) Allows to display the class 3 faults recorded during the last flight leg.
-GROUND REPORT (Ref. Fig. 021) Allows to present the class 1, 2 or 3 internal failures detected on ground. These failures differ from those displayed on the LAST LEG REPORT and CLASS 3 FAULTS. By pressing the line key adjacent to the failure message, the operator is allowed to access to the corresponding Trouble Shooting Data.
-TEST (Ref. Fig. 022, 023, 024) Allows a check of the correct operation of the WR/PWS on ground. This test can be performed by:
-either selecting the test function on the LCD of the WR transceiver
- or through the CFDS by selecting on the MCDU the test function on the RADAR 1 main menu page. At the end of the BITE TEST, the test pattern comes into view. (Ref. Fig. 025)
NOTE : If a failure of the windshear system is detected during the
____ BITE TEST, the windshear flags come into view. If the failure does not affect the radar mode, the test pattern stays available. If the failure affects the radar mode, nothing is shown.
All the information displayed on the MCDU during the BITE TEST configuration can be printed by the printer (Ref. 31-35-00).
