• Pillar 2: Management of Trajectory and Mission (MTM)

– The silent and agile aircraft will generate a reduced noise footprint

during approach and departure by flying optimised trajectories.

– Aircraft will be able to fly a green mission from start to finish, thanks

to technologies which allow to avoid fuel consuming meteorological

hazards

– Smart Operations on Ground

• Pillar 1: Management of Aircraft Energy (MAE)

– The use of all (more) -electric equipment system architectures

from electrical generation and distribution to electrical aircraft

systems.

– Thermal management will address many levels, particularly

relating to electric aircraft, from hot spots in large power

electronics to motor drive system cooling, to overall aircraft

solutions.

MCDP – ECO Take off : concept

Optimization of a Noise Abatement Departure Procedure (NADP) , with

multiple criteria � Multi-Criteria Departure Procedure (MCDP)

�Optimization of the Vertical profile. The lateral route is imposed

� NADP begins at 35ft and finishes at the en-route configuration (start of climb)

Thrust: Take Off Rating � Intermediate RatingIntermediate Rating � Climb Rating

Speed: V35ft+DV2 � Intermediate AccelerationIntermediate Acceleration � En-route Speed

�Optimisation Parameters

– Zpr : Thrust Cutback Altitude

– N1noise: Reduced Engine Rating

– Zpa : Acceleration Altitude

– Vnoise : Intermediate Speed Target

– Zpf : Setting of Climb Rating and Start of Acceleration to En-route Speed

– ∆V2 : fraction of speed at 35ft in excess of safety minimum (V2)

SGO/MTM – SESAR interface

Through its actions on “Management of Trajectory and Mission”, the

CLEANSKY Project will define, assess and deliver solutions, for different types

of aircraft, to achieve fuel and noise-optimized profiles in a wide range of

airports configuration

SESAR - CleanSky interface

• SESAR aims at developing compatibility of existing fleet with new ATM standards

• Clean Sky will provide more environment friendly breakthrough for next Aircraft generation

• Clean Sky solutions should be compatible with new ATM standards

In other words …

SESAR works primarily on traffic efficiency,

CLEANSKY on “cars” improvement.

Both are needed for the future of air transport
