A code change from an aircraft not in your area of responsibility should be requested only if

• A. The pilot requests it
• B. The area is not appropriate
• C. The aircraft is in distress
• D. Coordinated at the time of handoff or specified in a Letter of Agreement

Answer: (D)

When an aircraft isn’t in your area of responsibility, changes to its identification code must be coordinated with the next controller or facility that will handle it. This keeps the aircraft’s radar identity continuous and prevents confusion or conflicts between sectors. The handoff process is built on sharing the current code and the agreed method for any future changes, and a Letter of Agreement can designate who has authority to authorize such changes for cross-boundary flights. Only coordinating at handoff or per the LOA ensures all parties know the aircraft’s code and how it will be managed as it moves through different airspace. The pilot requesting a change doesn't by itself grant authorization if the aircraft is outside your area. Likewise, claiming the area isn’t appropriate or citing distress doesn’t remove the requirement for proper coordination before altering identification in another sector.
