LAST/CURRENT LEG ECAM REPORT
A CURRENT LEG ECAM REPORT is elaborated during the
flight. After the flight, its title becomes LAST LEG
ECAM REPORT.
The purpose of this item is to present the warning
messages displayed on the upper ECAM display unit
during the last/current flight. These are primary or
independent warnings.
Each message contains the ECAM warning, the ATA
reference and the flight phase and time at which the
warning was triggered.
When several identical and consecutive warnings are
transmitted, the CFDIU memorizes the first occurence
only and carries on counting with a maximum of 8.
The occurence counter is displayed between brackets
at the end of the message.
The CFDIU capacity for warning messages memorization
is up to 40 lines.
POST FLIGHT REPORT
The POST FLIGHT REPORT (PFR) is the sum of the LAST
LEG REPORT and of the LAST LEG ECAM REPORT.
The POST FLIGHT REPORT can only be printed on ground.
The list of ECAM WARNING MESSAGES and FAULT MESSAGES
with the associated time, flight phase and ATA
reference allow the maintenance crew to make a
correlation for easier trouble-shooting.
Beginning of PFR recording:
- If flight number inserted prior to first engine
start, first engine start + 3 minutes.
- If not, aircraft speed > 80 knots.
End of PFR recording: Aircraft speed < 80 knots + 30
seconds.

INTERNAL/EXTERNAL FAILURES
Each BITE can make the difference between an internal
and an external failure.
Let us suppose that an angle of attack sensor failure
has been detected and that systems A, B and C are
affected by this failure.
The Air Data System will transmit an internal failure
while systems A, B and C will transmit an external
failure.
FAILURE GRAVITY
The failures are classified according to their
importance:
- Class 1 failures are the most serious ones and
require an immediate maintenance action subject
to the Minimum Equipment List (MEL).
- Class 2 failures may have consequences if a
second failure occurs.
A maintenance action is necessary at the next
adequate opportunity.
- Class 3 failures can be left uncorrected
until the next scheduled maintenance check.
