§Various bumps were defined for the early A320
models, as a function of the customers requirements.
§For some latest A320 family models, the bump can
be made available upon request.
§These bumps provide between 6 and 10% more
thrust than the basic takeoff thrust.

§1 FLIGHT PLAN
1 Fuel Policy
The required fuel quantity for a safe trip along the
planned route is calculated for each flight. Each operator
has its own fuel policy. This policy is based on the
loading of minimum regulatory fuel requirements (FAR
121).

§1 FLIGHT PLAN
1 Fuel Policy
1.1 Domestic Operations
Taxi Fuel. In order to determine this amount, local
conditions at departure and APU consumption should be
taken into account. Taxi fuel is usually a fixed quantity for
an average taxi duration. For the A320 for example, it is
equal to 140 kg (300 lb). This corresponds to a 12-
minute average taxi fuel. Based on statistics or
evaluation, the taxi duration and
taxi fuel may need to be adjusted.
