When EDST is operational, a flight progress strip must be posted for which flights?

• A. When EDST is operational, a flight progress strip must be posted for any flight plan not contained in the Computer System, nonradar aircraft, or any strip deemed necessary for safe or efficient operations.
• B. Only radar flights contained in the EDST system require a flight progress strip.
• C. All flights must have a flight progress strip posted regardless of system status.
• D. Flight progress strips are never posted when EDST is operational.

Answer: (A)

When EDST is operating, a flight progress strip is still posted for flights that EDST cannot automatically display or track. That includes any flight plan not loaded into the computer system, nonradar aircraft, and any strip that is deemed necessary for safe or efficient operations. The purpose is to maintain a clear, visible record for controllers to monitor progress, issue updates, and coordinate handoffs when electronic data isn’t available or fully reliable. This preserves safety and efficiency even though EDST handles many flights electronically. The other options are too narrow or absolute: some flights outside EDST or not in the system still need strips, and not every flight requires a manual strip when EDST has complete, reliable data. Strips are not never posted; they are not always required for every flight when EDST fully covers the data.
