LAST LEG REPORT This section presents a portion of the information given in the PFR. It contains the class 1 and 2 fault messages transmitted to the CFDIU during the previous flight.
NOTE : For information purposes, the messages generated by the
____ identifiers are accessible in the last leg report of these

CES identifiers. The user who wants to use these messages must do so carefully as the information involved is non-correlated and non-priority information.
(4) 4th group
(a)
PREVIOUS LEGS REPORT The PREVIOUS LEGS REPORT function is the history of the LAST LEG REPORT limited to 64 flights. Therefore, it is displayed with the same restrictions.
(b)
TROUBLE SHOOTING DATA In most cases, this concerns primary and coded data. The purpose is to supply additional information on conditions prevailing when the maintenance message was generated. In general, these data are read in the case of events which do not result from effective part failure, already covered by the replacement of the failed part. Analysis of this data will be effectively useful in the study which may enable the identification of the cause of an event.
NOTE : In certain cases, this analysis can only be concluded with
____
the designer.
If certain trouble shooting data are required for fault trouble shooting, data readout will be requested by a TSM procedure. Wherever possible, these data will be displayed decoded on the MCDU.
(c) LRU IDENTIFICATION The purpose of this section is to display on ground the part numbers of computers of the selected system and possibly their serial numbers. This section may be consulted to check the interrogated computer standard. This is a configuration management aid.
(5) 5th group
(a) CLASS 3 REPORT All class 3 (internal and external) maintenance messages corresponding to the selected system are grouped under this report. This function enables a quick access to the class 3 messages of a given system.
NOTE : Some systems do not have class 3 reports.
