IFATCA Policy is:

Performance Indicators as published and used by Air Navigation Service Providers shall not be linked in any way to the pay and/or working conditions of individual ATCOs.

Global metrics for the performance of the Air Traffic Management System shall be developed through ICAO processes as soon as possible.

Controller expertise shall be used in the establishment and settings of metrics that measure the performance of the Air Traffic Management System

Controller expertise shall be used in establishing and reviewing models used for determining performance of the Air Traffic Management System to ensure that the models accurately reflect how the ATM system functions.

Controller expertise shall be used in the interpretation of data used to assess the performance of the Air Traffic Management System to ensure that data is not misleading because it is incomplete or incorrectly applied.

The measurement of performance of the Air Traffic Management System shall reflect the impact of any external-to-ATM constraints, including external environmental constraints.

IFATCA urges MAs to be involved in the creation and application of an ATM Performance Measurement System.
