Annual Additional Cost (US$)
However, in practice, the fuel consumption prediction of the Flight Plan can only be achieved if:
.
The cost index and speed (and altitude – refer to following section for further details) parameters stated in the Flight Plan are accurately followed,
.
The Flight Plan is an accurate representation of the flight to be undertaken.

Airbus Performance Engineering Program (PEP) Software Package
Several references to this software package are made throughout this document. Similar software packages are available from other aircraft manufacturers but the proprietary nature of the data makes the package applicable to the supplier’s products only. As such, Airbus PEP software provides unrivalled degree of precision in the optimization of efficient operations of its aircraft.
The Airbus PEP is comprised of several modules:
Flight Manual (FM): the FM module of PEP represents the performance section of the Flight Manual in a digital format for all aircraft (not available for A300).
Takeoff and Landing Optimization (TLO): takeoff calculation gives the maximum takeoff weight and associated speeds for a given aircraft, runway and aircraft atmospheric conditions. The takeoff performance computation is specific to one airframe/engine/brakes combination. The takeoff calculation computes takeoff performance on dry, wet and contaminated runways (except A300 B2/B2K/B4), taking into account runway characteristics, atmospheric conditions, aircraft configuration (flap setting) and some system failures. Note: runway and obstacle data are not provided by Airbus.
Flight Planning (FLIP): produces fuel predictions for a given air distance under simplified meteorological conditions. The fuel prediction accounts for operational fuel rules (diversion fuel, fuel contingency, etc.), for airline fuel policy for reserves and for the aircraft performance level. Typical fields of application are technical and economical feasibility studies before opening operations on a route.
