What time frame must GWO TWR adhere to when notifying ZAE of a delay in departure?

The appropriate time frame for GWO Tower (TWR) to notify ZAE of a delay in departure is three minutes. This requirement ensures that there is sufficient time for coordination and adjustments in air traffic management. A notification within this timeframe allows ZAE to effectively manage flow and optimize the use of airspace and airport resources, which is crucial in maintaining safety and efficiency in operations.

In the context of air traffic control, timely communication is essential to prevent potential conflicts and delays in the broader air traffic system. Adhering to the three-minute notification guideline enables controllers to make informed decisions regarding sequencing and other traffic adjustments needed as a result of the delay.
