Once formation aircraft have established separation, what should be provided to the pilots?

Providing advisory information for separation to pilots of formation aircraft after they have established separation is essential for maintaining safety and effective communication. When formation flying is involved, it's crucial for the pilots to be aware of their relative positions, any changes in traffic, and any impending airspace issues that might affect their flight operations.

Advisory information can include updates on nearby traffic, weather conditions, and any other relevant factors that could impact the formation's flight. This ensures that the pilots can remain aware and responsive to their surrounding environment while they fly in formation, allowing them to take necessary actions to maintain safety and efficiency.

While clearances for landing may be necessary at certain stages of flight, that typically comes later in the process once the formation is ready to land. Instructions to break formation could be relevant in specific circumstances, but providing advisory information regarding separation is more critical in ensuring the safety and operational integrity of the flight. Lastly, simply providing altitude details would not encompass the full spectrum of operational awareness needed by the pilots flying in formation. Thus, advisory information for separation is the most comprehensive and pertinent support that should be provided to formation aircraft pilots in this context.
