PFR FILTER PROGRAM
The purpose of this function is to improve the
operational use of the POST FLIGHT REPORT (PFR) by
filtering all the spurious or injustified
failures/messages.
It concerns the PFR printed at the end of the flight
as well as the real-time failure and warning
information transmitted by the ATSU.
Filter Activated
The filter data base is activated after correct
uploading. It can be deactivated then activated again
through the 2L line key.
This data base is a copy of the SIL (Service Information
Letter) 0028 under diskette form. It must be
periodically updated.
Print Filter Content
This function enables printing of the maintenance
filter data base.

GROUND/FLIGHT TRANSITION
Transition to flight (Event "1") is defined "at the
soonest" or "at the latest" depending on whether the
flight number has been entered by the crew before
take-off or not.
Event "1":
- "At the soonest": First engine start + 3 minutes
if flight number entered prior to first engine
start.
- "At the latest": Aircraft speed > 80 knots if
flight number not entered prior to first engine
start.
At event "1", the leg number is incremented.
"IN FLIGHT" PHASE
From event "1" until aircraft speed has been below 80
knots for 30 seconds, type 1 and 3 systems are
considered in flight.
NOTE: Type 2 systems are only considered in flight
from 30 seconds after lift off up to touch down.
In flight, the system Built-In Test Equipment (BITEs)
ensures:
- detection (Type 1/2/3 systems) and memorization
in their flight memory (Type 1/2 systems only
as type 3 system BITEs do not have any memory)
of internal and external faults,
- transmission to the Centralized Fault Display
Interface Unit (CFDIU) of internal and external
faults for memorization and establishment of
the CURRENT LEG REPORT.
This "in flight" phase corresponds to the Post Flight
Report (PFR) recording time (Beginning and end of fault
and ECAM warning message memorization in the CFDIU).
FLIGHT/GROUND TRANSITION
Transition to ground occurs when, after touch down,
the aircraft speed has been below 80 knots for 30
seconds.
At this time, the CURRENT LEG REPORT is renamed under
the title LAST LEG REPORT and is stored in the PREVIOUS
LEGS REPORT.
NOTE: As the leg has not changed, the content of the
