What does SIDA include at an airport?

The term "SIDA" refers to the Security Identification Display Area, which encompasses specific zones within an airport where security measures are strictly enforced to protect the integrity of the airport's operations and the safety of passengers. The correct answer involves both the Security Identification Display Area itself and the Secured Area, which is essential to understand as it highlights the comprehensive nature of SIDA.

These areas typically include parts of the airport that require security clearance for access, such as boarding areas, the tarmac, and baggage handling zones. This definition clarifies that SIDA is not limited to just one specific type of area, such as the passenger boarding area, but rather includes all designated zones where higher security protocols are mandatory.

While other options suggest more limited or unrelated areas, the correct understanding of SIDA entails recognizing its role in ensuring security throughout various critical areas of the airport, aiming to mitigate risks and protect everyone involved in air travel.
