RECAT - Wake Turbulence Recategorization

Aviation safety is a fundamental concern for all stakeholders. The traveling public demands the highest safety standards, but also wants convenience and reliability at a low price with minimal environmental impacts. Taking account of these sometimes competing demands can be challenging.

A common cause of flight delay is the limited capacity of airport runways. One solution is to build more runways, but this understandably generates opposition from local people and often takes a lot of time. Another solution is to increase the capacity of existing runways. This is normally less costly and sometimes generates less local opposition.
