Global ATM performance hierarchy
|Term||Global ATM performance hierarchy|
a construct [...] illustrating (and reminding the reader) that the performance-based approach can be applied at different levels, ranging from high-level socio-political issues to lower-level technology.
ICAO (2009), doc. 9883, Manual on Global Performance of the Air Navigation System
The hierarchy distinguishes between five levels: 1) political and socioeconomic requirements; 2) required air navigation system performance (RASP); 3) required total system performance (RTSP) at the level of ATM component functionality; 4) system performance requirements (e.g. RNP, RCP); 5) technology performance (including standards, specifications).
