Wake turbulence generated by an aircraft may be a hazard for the following aircraft. To protect against this risk, regulations specify minimum separation between aircraft during both approach and landing. Work is now underway to overcome this restriction, or at least to reduce the required separation under certain conditions, which would increase traffic capacity during peak periods and reduce saturation at heavily, used airports. In turn, this would enable postponing or avoiding the construction of new airports or runways, thereby considerably decreasing costs and environmental impact. One effective approach - ensuring the required level of safety - is to install systems onboard aircraft capable of remotely detecting wake turbulence. This approach is the "raison d'etre" of the MFLAME project. The MFLAME project main achievements are: -The realisation of a demonstrator, based on a 2µm lidar, with original tracking method and signal processing. -The test of this demonstrator on Toulouse airport, in a configuration very close to an on-board detection from a follower aircraft. -The effective detection of wake vortices for all types of aircraft (low, medium, high). -The pre study of multifunction equipment able to detect wake vortices and also other atmospheric dangers like wind-shear (even in dry air), clear air turbulence, hail. -The improvement of techniques and technologies for a future cost - effective multifunction airborne system (laser, optics, signal processing). -The definition attempt of a wake vortex severity factor. The MFLAME main result is the validation of the concept of on-board equipment for remote detection of wake-vortices, so as to guaranty the required level of safety during approaches at reduced separation distances. Industrial equipment for detection, warning and avoidance of wake-vortex, wind shear and other atmospheric hazards could be brought to market within 5 to 8 years.
