GRA program was launched on 1st September 2008 (GRA Kick-Off: October, 7th- 8th 2008), and will allow future regional aircraft to obtain weight reduction, aerodynamics efficiency and an higher level of operative performance w.r.t. “year 2000” technology level.
In order to achieve these so challenging results, the aircraft will be entirely revisited in all of its aspects. In fact GRA consists of five technological domains: Low Weight Configuration (LWC), Low Noise Configuration (LNC), All Electric Aircraft (AEA), Mission & Trajectory Management (MTM) and New Configuration (NC).

Main objectives of AEA is to demonstrate the feasibility of on-board systems new technologies and architectures enabling the application of the All-Electric approach for a Regional airplane which aims:
to completely delete the Pneumatic and Hydraulic power
to enhance the Electrical power
to apply new technologies which optimise the energy usage (Electrical and Thermal Energy Management) thus contributing to Specific Fuel Consumption reduction (estimated around 2-3%, based on previous preliminary studies)

New ConfigurationsNew Configurations
Next generation of Regional A/C will be strongly affected by the “Green Requirements”;
New aircraft, systems architectures and advanced configurations might be necessary to accomplishing such requirements;
Moreover integration of new technologies, propulsion in particular, will affect the overall A/C sizing;
Careful assessment is required to evaluate eco benefits, and overall competitivity as well;
