Civil aviation faces a mounting conflict between the rapid growth of traffic demand and the increasingly clear need to reduce emissions of the long-lived greenhouse gas, carbon dioxide. Use of hydrogen fuel may contribute to the resolution of this conflict. This paper reviews the problem and introduces the current European research.

Conventional methods of repair for metallic aircraft structures usually include the use of bolted or riveted metallic reinforcement by introducing the cutting of damaged areas, which is not suggested in aging cases, due to the reduction of strength. Although today the bonded repairs are considered more efficient than the mechanically fastened, each repair is looked-upon as tailored made for each job. However, for the industrial engineering and maintenance production line, there is a lack of appropriate technical manuals - standards and specifications to control the implementation of the repair as integrated method - from the design phase, up to application and quality assurance.

Future aero engines will need to be more reliable, have lower operating costs and have significantly lower environmental impact than those currently in-service. The EEFAE technology platform will test advanced technologies capable of providing significant improvement in future generations of aero engines

Faced with the urgent need to facilitate the next generation of Air Traffic Management systems and to alleviate the insufficient interoperability of its components, standardisation and validation activities have to be promoted. The AVENUE project brings to the public domain a set of interfaces and an ATC data dictionary defined by consensus of all stake-holders. The project goes on to prove the correctness of an architecture for open validation platforms with a first instance based at the Eurocontrol Experimental Centre which was built with existing ATC components provided by key European ATC players. This will constitute a solid basis for validation activities in the European Commission 5th Framework Programme and in other R&D programmes.

Aeronautics Days 2001 saw an important innovation relative to previous Community conferences - the introduction of an International Forum. This stream of the parallel sessions was devoted to accounts of aeronautical research programmes in various countries and some international organisations.

The first part of the article briefly introduces the Association of Aviation Manufacturers of the Czech Republic (ALV) and its international cooperation. The second part describes the general organization and funding of R&TD in the Czech Republic and gives some examples of aeronautical developmental and research activities in the Czech Republic. The final part shows general possible ways to facilitate the international collaboration with the Czech aviation industry represented by ALV.

Within the frame work of Brite-Euram programme CRASURV ‘Commercial Aircraft — Design for Crash Survivability’, technology is being developed for the design of composite air frames with respect to crashworthiness. A significant part of the project consists of the design, fabrication and drop-testing of two representative composite fuselage sections, to generate the experimental data needed for the validation of new energy absorbing structural concepts, validation of simulation tools to model and analyse these structures subjected to crash loads.

Research in normal operational environments indicates that the formal requirements for the aircraft maintenance system are frequently not fully or effectively implemented in practice. This gives rise to a pervasive ‘double standard’ with no effective means of reconciling official and unofficial operational practice. A systems strategy for human-centred management in aircraft maintenance is being developed in a number of European projects, which address issues of design, planning, operational practice, monitoring, change and competence.
