Fuel
There are many different fuel planning rules and regulations worldwide
or even differences between various aircraft types or the kind of opera-
tion within the same authority.
For example, a European airline would normally use EU-OPS fuel policy
as published by the EASA (European Aviation Safety Agency), whereas
an airline based in the United States would use FAA Domestic rules (For
domestic flights) or FAA Flag rules (For international flights).
Note: A European airline would always use EU-OPS planning ru-
les even when doing a domestic flight within the United States.
An airline based in the United States would always use FAA re-
gulations, even when conducting flights within Europe.
PFPX comes with a pre-defined set of fuel policies. These policies can be
adjusted as required with the fuel policy editor.
Normally, a dispatcher is looking for the minimum amount of fuel to be
carried for a specific flight, taking into account all legal and operational
requirements. In some circumstances it may be advisable to carry more
than the minimum amount of fuel (E.g. if the fuel at destination is ex-
pensive or if no fuel is available).
PFPX allows setting up a wide variety of fuel options to cater for diffe-
rent scenarios:
• Fuel policy: The fuel planning rules used for calculation depen-
ding on the operator’s legal requirements.
• MEL/CDL %: Missing or defective items may require increasing
fuel burn according to the MEL (Minimum equipment list) or the
CDL (Configuration deviation list). E.g. a value of 5% equals a
fuel flow increase of 5%.
