ArticlesEnvC Meeting RegistrationDear Delegates, Saturday 8 February 2014 at: Headquarters of Aeroclub of Italy The suggested hotels are: River Palace Hotel **** Giulio Cesare Hotel **** Single room: € 115.00 To book your hotel room, please directly contact the hotel of your choice. If you book by a simple e mail, do not forget to mention "special rate for Aero Club of Italy meeting" Visa RequirementsIf you require an individual invitation for visa purposes, please contact:Segolene ROUILLON, FAI Members Manager Headquarters of Aeroclub of Italy Via Cesare Beccaria 35/A 00196 ROME Italy Literature Reference ListThe Commission has compiled a considerable database of information on the real environmental impact of aviation to nature. Other information on noise measurement, planning issues, etc. is also being documented. This Literature Reference List serves as an instrument for those interested in these matters to find sound information. For the ease of use, website links and addresses are provided where either the referenced article can be found and downloaded or where the relevant organization is available which has a direct relationship to the article. ProjectsAll air sports interact with parts of the environment, considering air, land, sea, water, scenic views, wildlife, vegetation. Each air sport discipline has specific interactions with these parts of the environment. The development of facilities and the carrying out of air sport activities are to be conducted in a manner that harmonises the interaction between the air sport activities and the environment. The Environmental Commission has been created with the objectives set out in FAI Statutes:

A layman’s guide to the difficult subject of Noise MeasurementSummaryInternational Standards Organisation (ISO) agrees measuring methods etc. using international working groups. In the case of aircraft and airfield noise, International Civil Aviation Organisation (ICAO) may put forward standards based upon the ISO-recommended methods of assessment; the ICAO standards could (but not always will) form the basis of individual countries’ standards. ICAO has developed two methods for certification of take-off noise for individual aircraft types – “Chapter 6”, and “Chapter 10”. The latter is now most commonly used. The noise impact from an aircraft is measured as the total noise effect established on the ground 2.5 kilometres from the rolling point of the aircraft, on the extended centreline of the runway. The level is expressed in the universal “decibels" (dB). It is derived from the sum of the noise energy received over the most noisy 10 seconds from the start of take-off until well past the microphone, rather than the peak noise level. FAI has agreed to support the use of this as an appropriate measure for aircraft certification. Airfield noise, as experienced at a place such as a nearby house or a measurement spot, is usually expressed in the form of an average, over a certain period of time, for example a 16-hour Leq. It represents the sum of all the noises made by individual aircraft flying past. If the point of measurement were on the ground 2.5 kilometres from the rolling point of the aircraft and on the extended centreline of the runway, a good approximation could be derived from ICAO “Chapter 10” data. That is the method set out in Dr. P. V. Brüel’s 1998-99 paper, “Noise Evaluation of Small Airfields”. The calculated average is influenced heavily by the noisiest aircraft used, very little by any events 10 dB quieter than that, only moderately by the number of starts of the noisier aircraft, and hardly at all by the number of starts of the quieter aircraft. The Layman’s guide to the difficult subject of Noise Measurement has been prepared by Mr. Chris J. Nicholas, President of Honour of the FAI Environmental Commission.

Interaction of air sports with wildlifeA key issue on the agenda of the FAI Environmental Commission (EnvC) is to provide objective information about the interaction of air sports with wildlife. Air sports enthusiasts of all disciplines throughout the world need to know more about the various effects our activities have on nature, so as to be able to fly considerately. EnvC has initiated a series of translations into English of articles which describe the effects of air sport activities on wildlife and how to find solutions to manage the issues. The articles were first published in a German book entitled “Air Sports & Nature Protection”, published jointly by the German Aero Club and the German Federal Agency for Nature Protection. Although the case studies are mainly from Germany, they provide advice and practical help on how to manage environmental and nature conservation issues anywhere in the world. The first translations are now available on this page as PDF files. Further translations will be published on the EnvC website in the future.
