Which of the following is NOT a type of scan conducted when responding to an act or air piracy?

• A. discreet scan
• B. deliberate scan
• C. 6 o'clock
• D. random scan

Answer: (D)

In responding to an act or air piracy, scans are purposeful observations chosen to gather information while staying safe. A discreet scan means watching covertly without alerting suspects, so you can notice threats without tipping them off. A deliberate scan is a systematic, thorough sweep of the area to make sure no potential danger is missed. A 6 o'clock scan uses a specific vantage angle—often from a lower or rear position—to maintain cover while you survey the space for threats. Random scan, by contrast, is unfocused and lacks a planned pattern, making it unreliable and unsafe in a high-risk situation. Therefore, the option not used as a scan type is random scan.
