To whom should prior arrangements be made when flying in formation?

Making prior arrangements with other aircraft when flying in formation is crucial for safety and coordination. This ensures that all pilots are aware of the flight plan, the roles each aircraft will play during the formation flight, and any specific communication procedures that will be utilized. Formation flying demands a high level of teamwork and situational awareness among the pilots involved, as it involves closely coordinating maneuvers and maintaining proper spacing to prevent collisions.

While air traffic control plays an important role in managing air traffic, they are primarily focused on maintaining safe separation between all aircraft, including those in formation. Ground services are involved with logistical support but not directly with formation flying. Similarly, a flight instructor may provide training and guidance but would not be the primary point of contact for formation flight arrangements. Thus, making arrangements with other aircraft directly ensures that everyone participating in the formation is aligned and prepared for the specific challenges that flying in close proximity entails.
