Which scenario would necessitate a review of the current SOP?

The introduction of new safety regulations is a scenario that would necessitate a review of the current Standard Operating Procedures (SOP). Safety regulations are critical in the airline industry, and any change in these rules can significantly impact operational practices. An organization must ensure that its SOPs are aligned with the latest regulations to maintain compliance, ensure passenger safety, and protect the company's liability.

When new safety regulations are introduced, it often requires adjustments in training protocols, operational procedures, and even emergency protocols. This ensures that all relevant personnel are well-informed and prepared to adhere to the updated guidelines. The implementation of these changes can also affect a wide array of other operational areas, such as flight operations, ground handling, and passenger service.

In contrast, while the addition of new in-flight meals may involve some procedural updates, it does not carry the same level of urgency and impact on safety as new regulatory requirements. Changes in staff uniforms and updates to passenger feedback systems may be important for operations and customer service, but they do not directly relate to safety regulations, thus not warranting a comprehensive review of the SOP.
