AIDS: INDIVIDUAL PRINT REPORT DESCRIPTION
ENGINE MECHANICAL ADVISORY REPORT <07>
This report is generated when an exceedance of one of
the following secondary engine parameters is detected
on one engine:
- Engine oil temperature (OIT).
- Engine oil pressure (OIP).
- Vibrations of the engine LP rotor (VB1).
- Vibrations of the engine HP rotor (VB2).
The reason for exceedance is displayed (OIT, OIP, VB1,
VB2).
Basically, 5 sets of parameters for one engine are
recorded at 4 seconds intervals before the event, 1
set at the event and 4 sets at 5 seconds intervals
after the event.
The length of the pre-event and post-event intervals
(Y07.1 and Y07.2) is programmable.

AIDS: INDIVIDUAL PRINT REPORT DESCRIPTION
ENGINE DIVERGENCE REPORT <09>
This report is generated while in the climb or cruise
flight phases when, under stabilized conditions, any
of the following engine divergence conditions is
detected:
- Exhaust gas temperature (EGT) divergence
exceeding a programmed threshold.
- Nacelle temperature (TN) divergence exceeding
a programmed threshold.
The reason for divergence is displayed (EGT, TN).
This report is intended to detect quick degradation
in engine performance.
3 sets of parameters for both engines are recorded at
2 seconds intervals before the event, 1 set at the
event and 3 sets at 2 seconds intervals after the
event.
In addition, the following data is provided:
- E: Divergent engine (1 or 2).
- DIV: Absolute divergence value of EGT (or TN).
- REF: Reference delta value of EGT (or TN).
Since two engines do not behave with the
same performance characteristics, it is
necessary to establish a reference delta
for the divergence.
DIV = DIFF - REF, DIFF being the actual
delta value of EGT (or TN) between both
engines.

AIDS: INDIVIDUAL PRINT REPORT DESCRIPTION
ENGINE START REPORT <10>
This report is generated in case of aborted engine
start or EGT exceedance.
The possible aborted start reasons are:
- starter air valve or HP shut-off valve
demand/position disagree,
- EGT overtemperature,
- stall,
- no engine light off,
- hung start,
- illegal start sequence,
- slow start.
When effective, the reason is displayed (SAV, HPSOV,
EGT, STALL, NO LIGHT OFF, HUNG, START FAIL, SLOW).
"EGT" is also displayed in case of exceedance.
Basically, 3 sets of parameters for one engine are
recorded at 5 seconds intervals before the event, 1
set at the event and 3 sets at 2 seconds intervals
after the event.
The length of the pre-event and post-event intervals
(Y1 and Y2) is programmable.
NOTE: The engine start report is also generated (with
7 post-event datasets):
- every 25 engine cycles (programmable
frequency),
- every flight leg for 5 consecutive flight legs
from initialization (programmable number, up to
9).
