8. Display
_______ (Ref. Fig. 003, 004, 005, 006, 007, 008) The MCDU shows the APU information in normal mode and menu mode through the CFDS.
 A. Normal Mode During a normal mode the ECB continuously transmits all class 1 and 2 faults and messages to the CFDS. The MCDU display shows the faults and messages when the 'LAST LEG REPORT' is set. The Centralized Fault Display Interface Unit (CFDIU) makes the display on the MCDU in a normal mode.
 B. Menu Mode The menu mode is available on the MCDU display when the 'SYSTEM REPORT TEST' is set and an 'APU' selection is made. The MCDU display shows the related APU system data and the faults when a selection of the APU menu is made. The ECB makes the display on the MCDU in a menu mode. The APU menu includes the:
 -LAST LEG REPORT,
 -PREVIOUS LEG REPORT,
 -LRU IDENTIFICATION,
 -SYSTEM SELF TEST,
 -SHUT DOWNS,
 -APU DATA/OIL,
 -CLASS 3 FAULTS,
 -FAULT CONDITIONS
 (1)
 <LAST LEG REPORT> This gives the LRU failures (class 1 and 2) during the last flight leg, related to the system selection.

 (2)
 <PREVIOUS LEG REPORT> This gives the LRU failures (class 1 and 2) for the previous flight legs, a maximum of 30 failures of each class.
