Determination of Historics and Monthly data Release to HNDCAB
1. Type of Service
While there exist 4 types of service such as the Scheduled Flights, Ad-Hoc Flights, Business Aviation (BA) and General Aviation (GA), JSC coordinates only the Scheduled Flights. Other types of flights like Ad-Hoc Flights, BA and GA are treated by HNDCAB.
2. Monthly Data Release
JSC coordinates the Scheduled Flights up until around one month before the planned operations, then releases the monthly data of coordinated Scheduled Flights to HNDCAB. After its reception, HNDCAB will add Ad-Hoc Flights, BA and GA.
SCHEDULE OF MONTHLY DATA RELEASE TO HNDCAB
3. Monitoring of Flight Operations
After monthly data release to HNDCAB, JSC has no knowledge as to how the actual operations are conducted at the airport. HNDCAB is in charge of monitoring of all flight operations including the calculation of 80/20 usage.
4. Determination of Historics
The historic rights will only be given to the Scheduled Flights. As HNDCAB is in charge of monitoring of all flight operations, the calculation of 80/20 will naturally be done by HNDCAB. In its calculation, slots held
on file by JSC before monthly data release will be used as a basis for determination of historics.
5. Slot Historic List (SHL)
JSC provides each airline with the details of their historic slots as a SHL message based on the results of 80/20 calculation. These messages are distributed for each airport after the historic slots are determined, but not later than the SHL Deadline.
6. Review of SHL by Airlines
Airlines must review the SHL message and acknowledge its receipt to JSC. If an airline disagrees with the determination of historics, then it must contact JSC as soon as possible but no later than the Agreed Historics Deadline. If there is a disagreement regarding U/L calculation that cannot be solved with JSC, then an airline is encouraged to contact HNDCAB. It nonetheless remains the sole responsibility of the airlines to monitor the usage of their slot series.
