Economic Cost Effectiveness
The quality of service provided by ANSPs has an impact on the efficiency of aircraft operations. The service quality related costs need to be taken into consideration for a full economic assessment of ANSP performance.
The quality of service associated with ATM/CNS provision by ANSPs is, for the time being, assessed only in terms of ATFM delays , which can be measured consistently across ANSPs, can be attributed to ANSPs, and can be expressed in monetary terms. The indicator of “economic” cost-effectiveness is therefore the ATM/CNS provision costs plus the costs of ATFM delay, all expressed per composite flight-hour .
