International Scientific and Technical Soaring Organisation


The objectives of the OSTIV are to encourage and co-ordinate internationally the science and technology of soaring and the development and use of the sailplane in pure and applied research, the design, airworthiness and operation of gliders of all types, and the safety and training of pilots. The constitutional objectives of the OSTIV are achieved by seeking new knowledge, by encouraging dissemination through symposia and publications and by consultation with authorities.

OSTIV has the special status of an International Affiliated Member of FAI. Each party, the OSTIV and the FAI, has the right of representation –with voting right – in the General Conferences of the other party, and the right to appoint observers: the OSTIV to the meetings of the International Gliding Commission (IGC) of the FAI and the IGC to the meetings of the Sailplane Development Panel, the Training and Safety Panel and Meteorological Panel of the OSTIV.

Panels of OSTIV

Sailplane Development Panel

The Sailplane Development Panel (SDP) is the working group of OSTIV dedicated to all questions concerning the design and safety of sailplanes and powered sailplanes. About 25 members from all over the world meet at least once a year. The SDP is open for participation of interested persons as well as for proposals of topics to be discussed.
The SDP consults the International Gliding Commission of the FAI in technical aspects and the EASA concerning amendments of CS 22. The SDP also maintains the OSTIV Airworthiness Standard (OSTIVAS).
Some topics are prepared and handled in subgroups such as crash-worthiness, electric propulsion or appropriate gust load factors.

Training and Safety Panel

The Training and Safety Panel (TSP) collects and discusses safety records from member countries, compares training methods and successes, and develops strategies for mitigating risks through safety and training initiatives.
