When automated coordination is not available, what should be used for manual coordination?

The use of flight progress strips for manual coordination is essential in situations where automated coordination is not available. Flight progress strips provide a clear and concise visual representation of flight data, including key information such as departure and arrival airports, route, altitude, and communication information. This allows air traffic controllers to maintain situational awareness and track flight movements effectively.

Additionally, flight progress strips are designed for easy manipulation and reference, enabling controllers to quickly relay or adjust flight information during coordination with other controllers or facilities. This is particularly crucial in busy airspace where timely and accurate communication is vital for maintaining safety and efficiency.

While other options may offer certain relevant information, they do not provide the same level of utility and functionality in a coordination context as flight progress strips do. For instance, control center notes may contain valuable information, but they are not structured for quick reference or real-time updates like progress strips. Therefore, relying on flight progress strips during manual coordination is the most effective approach.
