"ATC Training Support for TMA RNAV - Electronic Training Package
AREA NAVIGATION IN EUROPEAN TERMINAL CONTROL AREAS (TMAs) has been developed by EUROCONTROL as generic training support material to enable controllers to understand the implementation and use of area navigation (RNAV) in the departure and arrival phases of flight. This package will be supplemented by local ATC training, which will highlight specific local implementation factors and issues. However, the content of this package will provide all stakeholders with a good understanding of P-RNAV and its use in Terminal airspace."
