Part C — Monitoring of the ATFM Function

1. In order to ensure the predictability and thus the performance of the UK ATMS, information about and adherence to planned operations and the ATFM measures are paramount. Therefore, a specific monitoring of the ATFM function shall be put in place.

2. The Secretary of State must endeavour to ensure that where adherence to ATFM departure slots at an airport of departure is 80% or less during a year, the ATS unit at that airport shall provide relevant information on the non-compliance and the actions taken to ensure adherence to ATFM departure slots.

3. In case of any failure to adhere to flight plan rejections or suspensions, the ATS unit at the airport concerned shall provide relevant information to the CAA on the non-adherence and the actions taken to ensure adherence.

4. The Secretary of State must endeavour to ensure that the unit providing central ATFM notifies the Secretary of State if exemptions in excess of 0,6 % of the United Kingdom’s annual departures are granted.

5. The Secretary of State must endeavour to ensure that the aircraft operator is notified of non-adherence to ATFM measures resulting from application of the requirements related to missing and multiple flight plans. Where an aircraft operator has been notified, it shall produce a report providing details of the circumstances and the actions taken to correct such non-adherence. The Secretary of State must endeavour to ensure that the unit providing central ATFM produces an annual report providing details of missing flight plans, or multiple flight plans that are filed.

6. The Secretary of State shall conduct an annual review of adherence to ATFM measures to ensure that all operational stakeholders improve the level of adherence to those measures.

7. The Secretary of State must endeavour to ensure that the unit providing central ATFM produces annual reports indicate the quality of the ATFM function including:

(a) causes of ATFM measures;

(b) impact of ATFM measures;

(d) contributions by all operational stakeholders to the optimisation of the overall network effect;

(e) recommendations on these various points to improve the network performance.

8. The Secretary of State must endeavour to ensure that an archive of ATFM data listed in this Annex, flight plans, operational logs and relevant contextual data is created and maintained by the unit providing central ATFM.
