Which of the following is NOT one of lead's responsibilities in a formation?

Choosing to identify "request altitude changes from ATC" as not one of lead's responsibilities in a formation is insightful because it highlights the specific tasks typically associated with lead pilots in formation flying. The lead's primary role is to manage the flight's tactical maneuvering and ensure the safety and effectiveness of the formation.

In formation flying, the lead is responsible for maintaining the flight path, clearing for the formation by looking out for potential hazards, and monitoring the position and performance of the wingmen to ensure everyone remains in the correct positioning. This includes assessing the surrounding airspace and making tactical decisions based on those assessments.

Planning ahead is also crucial for the lead. This involves anticipating changes in flight dynamics, adjusting for weather conditions, and executing maneuvers safely while considering the capabilities of the formation.

While the lead may communicate with ATC, requesting altitude changes is often a task delegated to a wingman or another designated pilot. In many training and operational contexts, this task may not fall directly on the lead because it can distract from their immediate responsibilities of leading and managing the formation's cohesion and safety.
