What action must a controller take when "FRC" appears on a flight strip?

• A. Notify the pilot of departure delays
• B. Issue the full route clearance
• C. Cancel the flight plan
• D. Request a new clearance from ATC

Answer: (B)

When "FRC" appears on a flight strip, it indicates that a full route clearance is required for the aircraft. This typically occurs when the flight is operating under conditions where a detailed route needs to be provided to ensure safe and efficient navigation along its planned path. In such cases, issuing the full route clearance is essential for the pilot to understand the specifics of the route they will be flying, including waypoints, altitudes, and any expected air traffic control instructions.

Providing this information allows the pilot to prepare for the flight and ensures that their navigation aligns with other traffic in the airspace. It also ensures compliance with regulations related to IFR (Instrument Flight Rules) operations, as pilots must follow certain procedures and guidelines when flying within controlled airspace.

The other choices would not be appropriate actions when "FRC" appears. For instance, notifying the pilot of departure delays does not address the need for a full route clearance, and canceling the flight plan or requesting a new clearance would lead to confusion and a lack of clarity regarding the intended route. Therefore, issuing the full route clearance is the correct and necessary action a controller must take.
