ADGS

ADGS - Aircraft Docking Guidance System

Hong Kong International Airport is equipped with Aircraft Docking Guidance System (ADGS). Currently, the system is connected to Airport Collaborative Decision Making (A-CDM) to provide departure information. Other features are not yet simulated.

EOBT - Estimated Off Block Time

This is the time you file in your flight plan to be ready for start-up.

TOBT - Target Off Block Time

This is the same as the EOBT if ATC do not change it in the system. It will be updated if you file a new EOBT.

You should be ready for start-up within +/- 5 minutes from/to the TOBT and call "ready for start-up" in the delivery frequency once you have the clearance.

TSAT - Target Start-up Approval Time

This is the the time when the start-up clearance may be expected.

Report ready at or before TSAT+-5. Your flight plan will become invalidated and may receive extra delay if you have not been cleared for start-up at TSAT+6.

You may get a earlier available slot if you report ready earlier.

NO CDM DATA

If you see "NO CDM DATA" in your ADGS panel, it means that your flight plan has either not been found, has been invalidated due to old EOBT, you have missed your TOBT/TSAT, or ACDM is not in use.

To receive a new TSAT, please refile your flight plan with a new EOBT or ask ATC to do it for you.
