When can support be given for the join-up of a formation?

Support for the join-up of a formation can be provided when any participating pilot makes the request. This is important as it allows for flexibility and responsiveness to the needs of the pilots involved in the formation flying. Each pilot in a formation may have different perspectives and situational awareness; thus, a request from any participant is sufficient to initiate support from Air Traffic Control (ATC).

Having this protocol ensures that ATC can efficiently manage the airspace and accommodate the needs of multiple aircraft while prioritizing safety and coordination among all involved parties. Supporting a formation join-up based solely on the lead pilot’s agreement or ATC's own discretion may restrict efficiency and inhibit participation by the other pilots. Similarly, tying this to weather conditions could also unnecessarily complicate the process when a simple request would suffice.
