Slot monitoring is directed to ensure that the scarce capacity at the airport is efficiently used. An adequate level of service quality should be maintained for the quality, flexibility and effectiveness of the coordination process to improve. In accordance with the European Council Regulation 95/93 as amended,
Slot monitoring is performed by ACNL in cooperation with the airport and air traffic control authorities. Several types of monitoring are applicable and procedures and regulations may differ per airport.
At Amsterdam Airport Schiphol a night time regime is in place. Operations during night time period without a proper night slot will be considered as a formal violation of the night regime, unless the airline can prove that the unplanned night movement was due to unforeseeable and unavoidable causes outside the carrier’s control. Airlines are recommended to review and abide to the applicable procedure and sanctioning system.
