5. Further events 2005
5.1Next training - workshop OSTIV MET-Panel in 2005:
A proposition by french representatives is to have it at St. Auban (FRA) in last week of September from 26/09 to 30/09/2005. The discussion was about : morning seminar and afternoon flights. The installations are well adapted : no transfert from accomodations to airfield or to the seminar. All is at the same place, with a nice sky to fly. All is possible to come with or witout glider and to fly on the gilder of the center.
A first idea of participation: about 8 persons are interessed to come. So, the meeting asked to the french representative to give confirmation of this, and if possible, to organise it.

a great discussion was about the role of this assembly. FAI and OSTIV are associated members. The OSTIV is involve in technics and meteorology, but not in sporting part. All results of workshops are published under the responsability of their authors, on the web site for information to all pilots or sporting organisations. Even for more information, everybody can ask to the authors or chairman. So, a great part of this assembly agree that no recommandations can be made to the sporting organisations.
