GM1 SKPI — General

Regulation (EU) 2019/317

A.      Purpose

This Annex contains the supporting material for measuring the safety key performance indicator (SKPI) and safety performance indicators (SPIs) in accordance with Commission Implementing Regulation (EU) 2019/317[37] (the performance and charging scheme Regulation) for the Third Reference Period (RP3).

B.      Objective

The objective of this Annex is to establish the method for the measurement and verification of the SKPI and SPIs under the performance scheme Regulation:

(a)      Effectiveness of safety management (EoSM) by ANSPs, which should be measured through a periodic answering of the questionnaires whose content is provided in the Appendix to AMC2 SKPI, GM3 SKPI and GM4 SKPI. The questionnaires, as completed by the ANSP subject to evaluation, and distributed in accordance with the performance and charging scheme Regulation, should be verified as detailed in AMC2 SKPI and GM4 SKPI;

(b)     Monitoring of separation minima infringement and runway incursion occurrence rates, which should be measured as detailed in AMC3 SPI and GM5 SPI;

(c)      Monitoring of the use of automatic safety data recording systems for monitoring and recording of separation minima infringements and runway incursions by the ANSPs, which should be measured as detailed in AMC4 SPI and GM6 SPI; and

(d)     Monitoring of the air traffic flow management (ATFM) over-deliveries, which should be measured as detailed in AMC5 SPI and GM7 SPI.

C.      Definitions and acronyms

Definitions

—          ‘Best (good) practice’ is a method, initiative, process, approach, technique or activity that is believed to be more effective at delivering a particular outcome than other means. It implies accumulating and applying knowledge about what is working and what is not working, including lessons learned and the continuing process of learning, feedback, reflection and analysis.

—          ‘Risk’ refers to safety risk and means the combination of the overall probability or frequency of occurrence of a harmful effect induced by a hazard and the severity of that effect.

—          ‘Safety culture’ means the shared beliefs, assumptions and values of an organisation and is part of the organisational culture.
