Welcome to Japan Schedule Coodination(JSC)

Japan Schedule Coordination (JSC) is an independent non-profit organization under the Japan Aeronautic Association (JAA) which is a national foundation established for the purpose of promoting the development of aeronautics and astronautics in Japan and enhancing the cooperation with world aerospace communities. JSC is in charge of slot allocation for Narita International Airport (NRT), Tokyo International Airport (Haneda) (HND), Fukuoka Airport (FUK) and Kansai International Airport (KIX), and schedule facilitation for New Chitose Airport (CTS).

Level Change of KIX (from L2 to L3)

Japan Civil Aviation Bureau has notified IATA of a change in the designated Level of Kansai International Airport(KIX) from Level 2 to Level 3. The change will take effect from the start of the Northern Winter 2021 season (NW21). JSC, who has facilitated the schedule of KIX, will be continuously assigned as a Coordinator of KIX.

All carriers serving KIX are reminded that they must be allocated a slot by the Coordinator before operating. Upon commencement of W21 coordination, JSC will determine the historic slots for each airline that operated at KIX in W20 based on the planned and operated schedules in W20 (U/L waiver will be taken into consideration) and will send SHL by SHL Deadline(19APR 2021). For details about the determination of historics, please see the page KIX Menu.

Slot Monitoring

10th Edition of IATA WSG became effective on 1 August 2019 which is downloadable from the bottom of this page. The significant change compared with the previous edition is the inclusion of “Slot Monitoring” which is described in a new Chapter 9. Based on this inclusion, the slot monitoring program will be initiated in Japan effective S20.

The purpose of this monitoring is mainly the calculation of 80/20, misuse of slots and on time performance (OTP). Slot monitoring is divided in two parts; Pre-Operation Analysis and Post-Operation Analysis. The results of the monitoring will be reported at the occasion of Airport Coordination Committee (ACC). The details can be found in the attachement. >> Attachment
