Night Vision Imaging System (NVIS) certification requirements analysis of an Airbus Helicopters H135

The safe operation of nighttime flight missions would be enhanced using Night Vision Imaging Systems (NVIS) equipment. This has been clear to the military since 1970s and to the civil helicopters since 1990s. In these last months, even Italian Emergency Medical Service (EMS) operators require Night Vision Goggles (NVG) devices that therefore amplify the ambient light. In order to fly with this technology, helicopters have to be NVIS-approved. The author have supported a company, to quantify the potentiality of undertaking the certification activity, through a feasibility study. Even before, NVG description and working principles have been done, then specifications analysis about the processes to make a helicopter NVIS-approved has been addressed. The noteworthy difference between military specifications and the civilian ones highlights non-irrevelant lacks in the latter. The activity of NVIS certification could be a good investment because the following targets have been achieved: Reductions of the certification cost, of the operating time and of the number of non-compliance.

The Experience of Helicopters subject-course in the OCW-UPM Project. A Proposal on Technology Dissemination.

An experience developed by the authors in the design of educational tools, funded on multimedia support for using in teaching, will be presented. These tools have been used on the subject of Helicopters, http://ocw.upm.es/ingenieriaaeroespacial/ helicopteros at the Universidad Politécnica de Madrid (E.U.I.T. Aeronáutica). Throughout more than ten years, these didactical and educational elements have been defined and developed. It has the singularity that most of them have been designed for undergraduate students, as a part of their end of degree projectwork. This peculiarity has led to a wide range of proposals and solutions, as well as an appropriate approach. depending on the level of knowledge. The evolution of tools for developing these materials will be presented, discussing advantages and disadvantages. Finally, we will advance the new materials which are being prepared at present.
