Which of the following is NOT one of the mandatory OPS checks?

• A. Prior to beginning area profile
• B. After lead change
• C. Prior to diverting to a secondary airport
• D. Prior to departing working area

Answer: (C)

The correct answer is the choice referring to "prior to diverting to a secondary airport." The mandatory OPS checks are essential safety procedures that ensure all operational aspects are thoroughly covered before and during a flight. These checks help maintain situational awareness and readiness for the pilots, ensuring safety protocols are followed. The mandatory checks, such as prior to beginning area profile, after lead change, and prior to departing the working area, are routine checks designed to confirm that all systems are functioning correctly and that the crew is aware of the flight status and surrounding environment. However, "prior to diverting to a secondary airport" is not categorized as a mandatory OPS check because while diversions do require appropriate procedures, such checks are not standardized as mandatory in the same way as the other listed checks. This choice highlights a specific operational scenario that, while critical, does not fit into the routine checks established for every flight phase.
