If the EDST Coordination Menu is used and the flight plan is subsequently changed, what action must be taken regarding the Coordination Indicator?

• A. When the EDST Coordination Menu is used and the flight plan is subsequently changed, remove the yellow coding from the Coordination Indicator after any appropriate action.
• B. If the flight plan is changed, keep the yellow coding on the Coordination Indicator until further notice.
• C. The Coordination Indicator color should be changed to green after any action.
• D. Yellow coding on the Coordination Indicator is removed only at the end of the shift.

Answer: (A)

Coordination indicators reflect the current status of flight plan coordination. When you use the EDST Coordination Menu and the flight plan is subsequently changed, you must remove the yellow coding from the Coordination Indicator after you have completed the necessary actions to implement and communicate the change. This clears the pending coordination signal and shows that the update has been acted upon, preventing confusion for others. Keeping the yellow coding until further notice would imply unresolved coordination, and changing it to green after any action could misrepresent whether all required steps were completed. Delaying removal until the end of the shift would leave the indicator showing outdated information for others.
