Cost of Weight (CoW) and Aircraft Performance
• Airbus’ Performance Engineering Programme:
• Powerful software tool comprised of several modules.
• Uses Airbus’ aircraft performance reference data.
October 2012 Saving fuel: it's a team sport
Tool to accurately assess value of weight reduction
• Used by airline’s flight operations
aircraft performance teams.
• Can calculate impact on fuel
consumption of a given weight
change on a specific route.
• Monitors aircraft performance and
its degradation with time.

Data: fuel efficiency programme foundation
Delivering and sustaining fuel efficient operations
requires data:
• to identify opportunities,
• to identify problems,
• to monitor and promote fuel efficient operations.
October 2012 Saving fuel: it's a team sport
Data collection is a crucial activity
Data set examples:
• APU utilisation
• Taxi times
• Engine thrust settings
• Flight profile speeds and altitudes
• Fuel consumption per flight phase
• Comparison of actual versus planned flight parameters
• Weight & Balance Parameters

Industry Actors
October 2012 Saving fuel: it's a team sport
• Fuel and Flight Efficiency can only be fully delivered
when all industry actors work together:
• Manufacturers’ design and build, with its suppliers,
aircraft which remain cost efficient throughout their lives.
• Aircraft Operators operate those aircraft in the most
efficient way.
• Air Traffic Management authorities and airports
provide an infrastructure that allows aircraft operators to
use their aircraft in the most efficient way.
• Regional, national and local governments create
environments where these objectives can be achieved.
