The purpose of 14 CFR Part 73 is to designate what type of airspace?

• A. Special Use Airspace
• B. Class A Through E Airspace
• C. Uncontrolled Airspace
• D. Terminal Area Airspace

Answer: (A)

Special Use Airspace is what 14 CFR Part 73 designates. This part establishes areas where flight activities are considered hazardous or sensitive and therefore require special handling to keep other air traffic safe. The types under Part 73—Prohibited, Restricted, Warning Areas, Military Operations Areas, Alert Areas, and Controlled Firing Areas—define where certain activities occur and what rules apply to pilots who encounter them. The purpose is to separate or protect those activities from routine air traffic and to alert pilots to potential risks in those areas.

Understanding this helps you anticipate when you might need special permission or should plan an alternate route. For example, entering Prohibited or Restricted areas typically requires authorization or must be avoided, while MOAs are designated to separate military training from other traffic, though pilots may pass through with awareness and appropriate separation. Warning Areas extend over international waters to warn nonparticipating pilots of activities, and CFAs suspend activity if needed to maintain safety.

Other airspace types like Class A through E or Terminal Area are defined in different parts of the regulations, so Part 73 specifically focuses on these Special Use areas and how they influence flight planning and operations.
