S-76B Certification for Vertical Take-Off and Landing Operations from Confined Areas.

摘要

The S-76B has been certified by the FAA for Category A operations from airfields, but not for vertical operations. The National Aerospace Laboratory NLR has generated the data necessary for certification of vertical operations by the Netherlands Department of Civil Aviation (RLD). For the project, use was made of a computer simulation program, that calculates two-dimensional flight trajectories after an engine failure during take-off or landing. Based on the initial results of computer simulations flight tests were carried out, during which single engine failure was simulated. Test data were recorded by video on board and on the ground. Calculated and flight test data were in good agreement over the considered range of masses, maneuvers and atmospheric conditions. Procedures for Category A vertical operations with the S-76B were determined with the use of the computer program and proposed to the RLD. They were approved and supplemented to the Flight Manual just four months after the flight tests.
