Environment friendly flight path (GRC5)

Challenge

Fast growth of rotorcraft operations to and from airports will generate an increase in gas emissions and footprint noise with helicopters following departure/approach routes designed for fixed wing aircraft. A significant fuel consumption reduction can be achieved with shorter IFR routes not interfering with aircraft traffic and taking advantage of the rotorcraft intrinsic agility. Based on activities already performed in the OPTIMAL and FRIENDCOPTER Integrated Projects, such flight procedures will be further developed. 

Expected benefits

The target for pollution reduction based on the GRC5 optimised flight paths is 6% of fuel consumption, while the new low-noise procedures developed in GRC5 contribute to reducing noise perceived by 5 EPN dB.
