Which document outlines anti-hijacking procedures?

The correct answer is the document that specifically addresses anti-hijacking procedures. AFI 13-207 is focused on anti-hijacking measures and outlines the necessary protocols to follow in the event of a hijacking attempt. It covers various aspects, including response plans, reporting procedures, and specific actions that crew members should take to manage the situation safely and effectively.

In contrast, AFI 21-501 pertains to aircraft maintenance and reliability, AFI 35-161 deals with family support programs and services, and AFI 10-100 focuses on the Air Force's continuity of operations planning. These documents serve different purposes and do not address anti-hijacking procedures, making AFI 13-207 the appropriate choice for this topic. Understanding the specific focus of each of these Air Force Instructions helps clarify why AFI 13-207 is the correct reference for handling hijacking scenarios.
