During Flag operations, flights may not be planned to operate at more than how many minutes from an adequate airport computed in still air with one engine inoperative?

During Flag operations, flights may not be planned to operate at more than how many minutes from an adequate airport computed in still air with one engine inoperative?

• A. 60 minutes
• B. 30 minutes
• C. 90 minutes
• D. 120 minutes

Answer: (A)

In Flag operations, the plan must keep you within a safe diversion radius to an adequate airport when flying with one engine inoperative. That radius is 60 minutes of flight time, computed using still air speeds. This ensures you have a practical and consistent amount of time and fuel to reach a suitable airport if an engine fails, regardless of wind conditions. An adequate airport means one with a suitable runway and services to support a safe landing. Winds can affect actual ground distance and time, but the rule uses still air to provide a reliable planning limit.
