The conservative Fuel Lower Heatin‐g Value (FLHV) is 18400 btu/lb.
When an aircraft ages, fuel consumption degradation will be measured to determine the so-called
“monitored fuel factor”. This factor corresponds to the deviation of the aircraft’s actual fuel
consumption from the nominal model. Generally, the FLHV that is used during fuel factor
monitoring is higher than the FMS value.
In order not to penalize FMS predictions, it is necessary to correct the “monitored fuel factor”.
For example, add -1 % to the “monitored fuel factor”, when an FLHV of 18590 btu/lb is used.
Once this factor is established by the airline, it should be arithmetically added to the above-noted
performance factor.
Applicable to:
PERF FACTOR VALUES
The PERF factors to be used on FMS2, depending on engine type, are:
‐ A340–211 CFM56–5C2: -2.0 %
A340‐–212 CFM56–5C3: -2.5 %
A340‐–213 CFM56–5C4: -1.0 %
A340‐–213E CFM56–5C4: 0.0 %
A340‐–311 CFM56–5C2: 0.0 %
A340‐–312 CFM56–5C3: -1.0 %
A340‐–313 CFM56–5C4: 0.0 %
A340‐–313E or A340–300B CFM56–5C4: +0.5 %
A340‐–313E/P or A340–300B CFM56–5C4/P: 0.0 %
All these numbers assume that:
The aircraft is brand‐-new
Anti‐-ice is OFF
The air conditioning is on LOW for A340‐-200/300 aircraft

In order not to penalize FMS predictions, it is necessary to correct the “monitored fuel factor”.
For example, add -1 % to the “monitored fuel factor”, when an FLHV of 18590 btu/lb is used.
Once this factor is established by the airline, it should be arithmetically added to the above-noted
performance factor.
Note: 1. At delivery, ENTER the PERF factor (given in the table above) directly in the MCDU
(no correction factor is needed).
2. When replacing an FMS1 Legacy by an FMS2, on any given aircraft model, the
performance model that is stored in the FMS2 may be different from the one that was
previously stored in the FMS1 Legacy.
As a result, DISREGARD the PERF factor previously entered in the MCDU.
ADD the “monitored fuel factor” (when available) to the PERF factor (given above),
and ENTER the resulting factor in the MCDU.
