What is the minimum altitude the lead aircraft will hold at during an orbit?

The minimum altitude that the lead aircraft will hold during an orbit is typically set at 1,500 feet AGL (Above Ground Level). This altitude strikes a balance between maintaining adequate separation from the ground while also ensuring that the aircraft is high enough to avoid potential obstacles in the surrounding area.

Flying at 1,500 feet AGL allows for better operational flexibility, particularly in environments where terrain may vary significantly. It also complies with many aviation regulations that mandate a safe altitude for aircraft maneuvers, particularly in training or operational contexts involving multiple aircraft.

Choosing an altitude like 1,000 feet AGL could potentially increase the risk of encountering ground obstacles, while altitudes higher than 1,500 feet may not be necessary and could complicate coordination efforts. Therefore, 1,500 feet AGL is the standard minimum altitude for orbiting aircraft to enhance safety and operational efficiency.
