The two types of airspace coordination areas are ____ and _____.

• A. Informal / Formal
• B. Formal / Standard
• C. Informal / Standard
• D. Narrow / Broad

Answer: (A)

Airspace coordination areas are managed through two coordination styles: informal coordination and formal coordination.

Informal coordination is quick and flexible, often handled verbally between units and the airspace control authority to enable rapid operations. It’s useful for urgent actions or tempo missions where speed is essential, but it may lack formal documentation or traceability and might not address every safety constraint.

Formal coordination uses documented procedures and official channels, with planned requests and approvals that create a clear, auditable record. This approach is important for planned, complex, or higher-risk operations where consistent deconfliction and adherence to airspace control measures are critical.

The other phrasing doesn’t reflect recognized categories of airspace coordination, since “standard,” “narrow,” or similar terms aren’t used to describe the two main coordination styles.
