Approach Path Monitor (APM) Guidelines

EUROCONTROL Guidelines for Approach Path Monitor - Part I to III - EUROCONTROL-GUID-162 - PUBLISHED

Ground-based safety nets are functionalities within the ATM system with the sole purpose of monitoring the environment of operations in order to provide timely alerts of an increased risk to flight safety.

Approach Path Monitor (APM) is a ground-based safety net that warns the controller about increased risk of controlled flight into terrain accidents by generating, in a timely manner, an alert of an unsafe aircraft flight path during final approach.

These Guidelines - mainly aiming at supporting Air Navigation Service Providers - specify the minimum requirements and provide comprehensive guidance for the definition, implementation, optimisation and operation of Approach Path Montior (APM).

PART I - describes the APM concept of operations and specific requirements on APM

PART II - contains overall guidance for the complete lifecycle of APM

PART III - specifies a generic example of an APM implementation and provides detailed guidance for optimisation and testing of APM


Together with similar Guidelines for Short Term Conflict Alert (STCA), Area Proximity Warning (APW) and Minimum Safe Altitude Warning (MSAW), these documents provide Level 3 documentation for evolutionary improvement of ground-based safety nets.



These Guidelines have been developed following the EUROCONTROL Standards Development Process and have been submitted to a two-staged Informal Stakeholder Consultation before their final approval and publication.
