Reduced separation minima (RESET)
Current Separation Minima (SM, i.e. minimum distances aircraft need to fly apart from each other at all times to ensure safety) were defined in the late 1940s for en-route and in the 1970s for airport operations, based on expert judgement and technology available at the time. Despite the gigantic leap in technology since, only but a few SM have been modified on the grounds of modern technological capabilities (e.g. RVSM).
Conversely, the main current ATM system challenge is to manage the air traffic demand increase expected over the coming years. According to forecasts, demand is expected to treble by 2020. The RESET aim is to identify what reductions in SM could be realised to meet the following challenging goal: "Where feasible, reduce SM so that they contribute towards enabling a safe factor of 3 traffic growth over Europe". At least three potential separation standard modifications will be selected for detailed safety, efficiency and economic assessments.
