Helicopter Height-Velocity (H-V) limitations

This Notice of Proposed Amendment (NPA) addresses a regulatory issue related to Commercial Air Transport (CAT) with large helicopters performing performance class 2 (PC2) operations where the Height-Velocity (H-V) envelope may be penetrated. This is typically the case during take-off and landing at offshore locations, public interest sites and in hostile environment outside a congested area.

This NPA proposes amendments to Regulation (EU) No 965/2012 and EASA Certification Specifications to Large Rotorcraft (CS-29) to allow penetration of the H-V envelope during the take–off and landing phases of PC2 operations.
