MISSION

ACNL aims to ensure that slots are being used as indicated at the time of allocation in order to achieve that scarce capacity is being used in the most efficient way. ACNL will comply with the European Council Regulation 95/93 as amended to monitor the use and adherence of allocated airport slots at Amsterdam Airport Schiphol, Rotterdam The Hague Airport and Eindhoven Airport.

PRINCIPLES

EC Regulation 95/93, as amended, stipulates that the coordinator shall monitor the conformity of air carriers’ operations with the slots allocated to them. These conformity checks shall be carried out in cooperation with the managing body of the airport and with the air traffic control authorities and shall take into account the time and other relevant parameters relating to the airport concerned.

Slot monitoring at coordinated airports is a continuous process designed to ensure that most effective use is made of scarce capacity, an adequate level of service quality is maintained and intentional schedule abuse is separated from the normal variations in operational performance.

PRINCIPLES

The main objective of slot monitoring should be to identify possible problems regarding the use of slots and seek solutions before they occur whenever possible, or as soon as possible after the date of operation.

All procedures related to slot monitoring must be based on the principles of neutrality, transparency and non-discrimination

SPECIAL ATTENTION

For monitoring purposes the airlines involved in joint operations, code share agreements etc. are required to make sure that both codes of the flights of the carriers involved are in the airport information systems. Moreover ACNL must be informed by both carriers involved of the details of the slots involved (for example, operating flight number) and the period of the joint operation, code share or other cooperation.

In such situation it is the responsibility of the airlines to deliver the correct information to ACNL; every last minute change must be sent to ACNL by the slot holder as an SCR (except operational changes on the day of operation).

Airlines that operated without an airport slot are also being monitored. An overview of these airlines may be published regularly.
