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.

This function should monitor all type of errors which may affect the aircraft ability to follow the desired flight path.

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

Agreeing PBNAgreeing 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+ alerting

This is different to 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.
