In-flight simulation as a general research technique has been applied by DFVLR since the early 1970's using the HFB 320 aircraft. This in-flight simulator was successfully used in various handling qualities flight experiments until 1984. Based on the experiences gained with the HFB 320 a new advanced in-flight simulator ATTAS (Advanced Technologies Testing Aircraft System) based on a VFW 614 aircraft has been developed recently by DFVLR which will be operational in 1986. The in-flight simulation concept of ATTAS encloses a full authority dual-redundant digital fly-by-wire/light system based on nine fibre optic-linked computers. Direct lift modulation capability has been added by using fast moving trailing edge flaps. Besides of a research application overview, safety and operational aspects will be dealt with.
