RNPSORSGRNP Concept issues

On-board performance monitoring and alerting function. A function on board the aircraft that detects and informs the crew when the RNAV system is unable to satisfy the performance prescribed in the navigation specification.

The required level of on board monitoring and alerting is stipulated in each RNP specification.

Agreeing PBN

PBN specifies RNAV system performance i.e. accuracy, PBN specifies RNAV system performance i.e. accuracy,

integrity, continuity, availability + functionality; - written integrity, continuity, availability + functionality; - written

up inup in navigation specificationsnavigation specifications

RNP X specifications RNAV X specifications

Require on-boardperformance monitoring+ alerting

Do not require on-boardperformance monitoring+ alering

This is different than the RNP concept, which stressed navigation accuracy and ‘stopped’ at required performance. However, PBN is anchored in detailed navigation specifications, which contain performance and functionality requirements.
