ROTORCRAFT IN SRA 2

 ACARE (Advisory Council for Aeronautical Research in

Europe) SRA2 (Strategic Research Agenda) has stated an increasing role of rotorcraft as a competitive and affordable mode of transportation for point to point connection, compared with road transport and with reduced impact on infrastructures. Application both on new and scheduled services.  The future ATS (Air Traffic System) model includes

rotorcraft contribution based on both current and future technology.

ENVIRONMENTALLY FRIENDLY FLIGHT PATHS (2/2) Continuity with FRIENDCOPTER and OPTIMAL FP6 IPs

Rotorcraft Platform

 Rotorcraft-specific approach procedures:  For instrument flight (IFR)  GNSS guidance  Noise reduction achieved only by steep slopes

 Minimisation of noise footprint (30 to 50%) by optimised design and flight paths:

 Environmentally friendly flight paths:  Both for VFR and IFR  GNSS guidance  Noise minimisation by optimised departure & approach paths, depending on H/C class

 For visual flight (VFR) only  Noise reduction by optimised paths, depending on H/C type Clean Sky JTI Rotorcraft Platform – Budapest 27-28 November 2006
