The SESAR fuel efficiency performance ambition primarily addresses the ATM-related fuel consumption within a gate-to-gate scope. It therefore covers efficiency on the airport surface, as well as both horizontal and vertical flight profile efficiency throughout the flight trajectory. The aim is to reduce the impact on fuel efficiency performance while maintaining the ability to accommodate traffic increases in a safe manner.
The SESAR performance ambition is to enable an average reduction of approximately 250-500 kg of fuel per flight (i.e. approximately 5-10 % of 4 800 kg of average consumption for a representative flight). This ambition addresses airport surface operations, TMA climb and descent operations and en-route vertical flight efficiency. It is broader than is currently targeted by the SES Performance Scheme, which focuses on the horizontal en-route flight extension only and aims to achieve 2.6 % in flight extension by 2019 compared to the 2012 baseline of 3.2 % (26).
The SESAR ambition of enabling approximately 250-500 kg fuel burn reduction is, on average, most likely to be enabled across operating environments as follows:
Airport surface operations: 38-75 kg fuel burn reduction per flight due to more efficient taxi operations, representing 30 % reduction in average taxi fuel burn per flight.
TMA climb/descent operations: 163 - 325 kg fuel burn reduction per flight due to the reduction in the use of stacks and/or holding patterns in the descent phase and more efficient climb and descent profiles, representing a 10 % reduction in average climb/descent fuel burn per flight. It should be noted that a significant portion of this improvement relates to TMAs serving the busiest and more congested airports in Europe.
En-route cruise operations: 50-100 kg fuel burn reduction per flight due to more direct cruise trajectories and more efficient vertical profiles, representing a 2.5 % reduction in average en-route cruise fuel burn per flight.
