Which entities can approve Letters of Agreement (LOAs)?

Letters of Agreement (LOAs) are formal documents that outline the responsibilities and procedures between different air traffic service providers or between providers and users. The approval of these agreements is typically the responsibility of individuals with the requisite knowledge and authority within the air traffic management structure.

The entities mentioned in the correct choice—ATREP (Air Traffic Representative), ATM (Air Traffic Manager), and RADLO (Radar Airspace Liaison Officer)—are specifically designated roles within the air traffic control system, each responsible for overseeing different aspects of air traffic management and ensuring that agreements align with operational protocols and safety standards.

ATREPs serve as the primary point of contact for coordinating operational issues, ATM has overall authority for air traffic operations in a given area, and RADLOs focus on aspects related to radar usage and coordination. Their roles involve ensuring compliance with regulations, maintaining safety, and facilitating communication between the various parties involved in air traffic management, which is critical in the approval process of LOAs.

In contrast, the other options—air traffic controllers, flight operations managers, and flight safety officers—may play important roles in operations and safety but do not typically hold the authority to formally approve LOAs. Their functions usually focus on daily operations, safety oversight, and ensuring adherence to
