Publication of Shedule to External Systems

A schedule formed in the System may be published into external systems. In this case, a part of parameters reflecting commercial components of a flight schedule might be partially changed without any change in basic schedule.

Messages are published in the form of TTY SSIM4/5 format (SSM messages are formed in compliance with basic periods, ASM messages are formed in compliance with Ad-hoc periods). For more information about TTY format, see SSIM standard, Chapters 4-5.

Flight schedule publication can be carried out in automatic and manual (forced) modes.

Automatic flight schedule publication is carried out after saving any schedule changes if rules of publication are formed. The schedule publication parameters are managed by the following business rules:

• Flight publication
• DEI by Leg
• DEI by Segment.

Formed messages contain tags of the actions that correspond to performed operations on schedule updating.

In manual mode, it is possible to send a flight schedule for a specified period by SSIM 4/5 format message.

Message format and conditions are defined by conditions of the Flight publication business rules.

When a message about a schedule is sent, a recipient system forms and sends a NAC response message (if such function is available) which contains information about receiving of the sent messages and processing status.

NAC incoming messages are added to system queue.

If the message is not processed by the recipient system then the NAC message contains information about processing failure cause. In this case, intervention of an operator is supposed: to change the schedule in accordance with the message information or edit the sent message about the schedule and resend it.

The messages are formed with tags of the actions that correspond to processed operations of schedule correction.
