READY to Depart Message

Function presentation

This window is used to send a READY to Depart message (REA) for a selected flight.

Opening the window

This window may only be activated when a flight is selected in a list or from the flight data window.
The REA message can only be sent for flights with a published slot and which are not yet active.

When such a window is opened, no other function may be invoked.
This display shows the READY to Depart Message to be sent. This message is sent when the flight is ready to depart before its EOBT.
There is no reply to such a message.
The Opened box at the top indicates the local PC stamp when this dialog was invoked. It is displayed there because the timing in sending messages is important.
The different data elements to be included in the message are presented on display :

• TITLE - REA naming the message.
• ARCID for the callsign of the flight.
• ADEP aerodrome of departure.
• IOBT/D Initial Estimated Off Block Time and Date.
• EOBT/D Last Estimated Off Block Time and Date.
• ADES aerodrome of destination.
• MINLINEUP Minimum time needed for the flight to get from its present holding position to airborne (if not provided, the taxi time is used).
• AFTN or SITA address for the reply.

The field IOBT/D for the Initial OBT is only displayed if it is different from the last OBT known.
The message is already prepared and only the MINLINEUP field can be supplied.
If a default AFTN or SITA address is defined, it is presented in the Originator Address drop-down box. To have a default address defined, you need to update the Message Originator preference (Preferences / CHMI / ATFCM application / General / Origin / Default Adress Id).
To modify the proposed address, click on the AFTN, SITA or None radio button to possibly modify the type and then select an address in the drop-down control or input one manually.
If no address is supplied on display, none will be included in the message.
The system will process the message and transmit a Slot Revision Message, if a new slot is available, to all concerned including the address you have provided with the message.
To send the message, click on Send button.
To close the window without sending the message, click on Cancel button.

Displaying the query results

After clicking the Send button, the message is issued to the CFMU system.
There will be no reply on the screen once the message has been transmitted. To acknowledge a good transmission, the transmit stamp is returned and displayed.
The processing of the message being un-synchronised, be aware this is only an acknowledgement message.
If a problem occurs in the transmission, a descriptive error message is displayed in the bottom message box.
All controls are disabled while processing the message.
Once the message is transmitted (successfully or not), the Cancel button becomes Close button and allows to terminate the dialog properly.
