What is the height restriction for air traffic control towers of Type IIB construction?

• A. 75 feet
• B. 85 feet
• C. 90 feet
• D. 100 feet

Answer: (B)

The height restriction for air traffic control towers of Type IIB construction is set at 85 feet. This specific standard is based on the building code regulations that govern the construction and design of structures to ensure safety and functionality, particularly for essential facilities such as air traffic control towers. Type IIB construction is defined by non-combustible materials and allows for certain height limitations in relation to their use and structural integrity.

Air traffic control towers must maintain a height that balances visibility, safety, and operational needs, with the established limit of 85 feet being a crucial factor. This height ensures that controllers have an unobstructed view of the surrounding airspace while also adhering to code requirements designed to mitigate risks associated with construction and operational hazards. Thus, the 85-foot limitation serves as a critical guideline to maintain safety standards in such essential structures.
