What altitude change does the aircraft perform in response to a lost link below ILLA?

When a MQ-9 aircraft experiences a lost link scenario below the In-Flight Loss of Link Altitude (ILLA), it is programmed to perform a specific maneuver to ensure safety and maintain operational integrity. The correct response is that the aircraft begins a 2.5 NM climbing orbit.

This maneuver is designed to allow the aircraft to safely regain communication while reducing the risk of collision and maintaining a controlled flight path. By climbing and orbiting, the aircraft creates altitude separation from any potential obstacles and increases its chances of reestablishing a link with the ground control. This action not only helps to preserve the mission objectives but also ensures that the aircraft remains in a secure flight pattern until normal operational status can be restored.

In contrast, the other options do not align with the established protocols for the MQ-9 in lost link situations. Descending or maintaining a constant altitude could increase the risk of hazards or complicate regaining control, while climbing to a fixed altitude like 5,000 feet may not be appropriate in terms of operational efficiency and safety, especially considering dynamic factors such as airspace restrictions or terrain. Therefore, initiating a climbing orbit ensures that the aircraft can adapt effectively to the lost link condition while focusing on re-establishing communication with minimal
