What document specifies procedures for areas without radar communications concerning ATCAA and MOAs?

The correct choice identifies the Letters of Agreement (LOA) as the document that outlines procedures for airspace coordination, especially in areas lacking radar communications, particularly concerning Air Traffic Control Assigned Airspace (ATCAA) and Military Operations Areas (MOAs). LOAs establish mutual understandings and protocols between military and civilian air traffic controllers, ensuring that operations can be conducted safely and efficiently in radar-less environments.

These agreements detail specific operations, such as how to manage air traffic in designated moas, and ensure that all parties are aware of the operational capabilities and limitations when radar data is unavailable. Other document types, while relevant to airspace management, do not specifically serve the same purpose in this context. Therefore, LOAs play a crucial role in operational safety and communication between different service branches and civilian entities when radar is not available.
