Schedules Information Standards Committee (SISC)

The Schedules Information Standards Committee (SISC)  is responsible for the development procedures and formats for the exchange of schedules data and SLOT information messageing standards, maintained within the Standards Schedules Information Manual (SSIM) 

SISC meets annually prior to the June Slot Conference. The Slot Conference (SC) is a working conference. As part of the slot process and SSIM standards the conference provides a forum for the allocation of slots at fully coordinated airports (Level 3), and for the reaching of consensus on the schedule adjustments necessary to conform to airport capacity limitations (Level 2).

The SSIM is published annually in March and the SSIM Web Download application will receive updated content throughout the year.  The SSIM is the official set of Recommended Practices that guide the industry along mutually compatible lines in the development of schedules/Slots data handling procedures. Full consideration is also given to the needs of those agencies which also require schedule related data, including government departments, airport and air traffic control authorities, timetable publishing agencies, fuel companies, etc. The manual aims to set common standards for external exchanges.

The SISC also recommends amendments to aircraft type codes , airport passenger terminal codes, time zone information and region codes published as part of SSIM standards.

MCT IMPLEMENTATION WORKGROUPS TRAINING Schema Downloads

Following PSC adoption of the new SSIM Chapter 8 - Presentation, Application, and Transfer of Minimum Connecting Time (MCT) Data the new standards are now included in SSIM 28th Edition. This Chapter describes the rules for submission and application of MCT for processing. In order to facilitate industry-wide implementation, a range of optional features, such as the use of suppressions, codeshare indicators and other optional MCT data elements, etc. have been included. Cutover to the new MCT standard in Chapter 8 is October 27, 2019.

As a result, the Minimum Connecting Time (MCT) section under Appendix H has been deleted in SSIM and will remain in the Appendix H- MCT (pdf) and within the SISC website for reference until October 26, 2019.

This page is used as a repository of all documentation required for the awareness and implementation of the new MCT standards.
