Which of the following is NOT one of the four TSA regulated security areas at an airport?

• A. Sterile Area
• B. AOA
• C. SIDA
• D. Public Viewing Area

Answer: (D)

Security zones in airports are defined by TSA and require different levels of access control. The Sterile Area is the secure portion you reach only after passing screening, where only screened passengers and authorized personnel can go. The Air Operations Area (AOA) covers the airside ramp and areas directly around aircraft, with access tightly controlled by badges, escorts, and perimeter security. The Security Identification Display Area (SIDA) refers to zones that require an approved badge to enter, ensuring that only authorized workers can access those spaces. Public Viewing Area, on the other hand, is a space intended for spectators and is not a TSA-regulated security area. It does not require the same security credentials or access controls as the three zones above, which is why it isn’t considered one of the TSA-regulated security areas.
