6 GRA Overview 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).
