Abstract	The presentation will give an overview and some results from the national German WASLA-HALE project. WASLA-HALE is the abbreviation for a mixed German/English language label which refers to “long range imaging and sensing flight vehicle assisted reconnaissance - High Altitude Long Endurance”. The programme is funded by the “Bundesamt für Wehrtechnik und Beschaffungen” which is the German Federal Office for Defence Technology and Procurement. It has been started in 2000 and will end in 2008 and it is accomplished by altogether 5 partners from Germany. The general objective of the WASLA-HALE study is the demonstration of techniques and procedures for integration of unmanned aerial vehicles in the common airspace. The main requirement for UAV integration into existing air traffic flying in common airspace is the fact that their operation should not have any impact on air traffic and safety! The main objectives are the demonstration of standard and emergency procedures, the development of certification standards for operation in controlled airspace and the presentation of reliable procedures for operation with two ground control stations. Furthermore certification requirements for sense & avoid capabilities are studied and technologies for UAV sense & avoid are developed. The programme is focussed on real flight demonstration for which DLR’S flying testbed ATTAS was chosen due to its outstanding capabilities (e.g. fly-by-wire flight control system, payload/experimental equipment capacity, spacious cabin, already existing on-board flight test and data recording equipment). Last but not least the DLR experience in test aircraft preparation (modification, integration and certification) plays an important role for the success of the programme. Standard and emergency procedures were flight tested in the period from 2002 to 2004. Two sense and avoid flight test campaigns were performed in May and October 2007. These activities are planned to be continued.
