Which rows are noted for cabin secure checks?

The correct choice is based on the specific procedures and protocols implemented for cabin secure checks within the Ryanair operations framework. Rows 21-33 are designated for cabin secure checks because this range typically encompasses the area where passenger movement is most concentrated and where safety checks can be effectively managed.

In this specific range, cabin crew are trained to pay close attention to securing luggage, ensuring that safety equipment is accessible, and verifying that all passengers are properly seated with their seatbelts fastened. These checks are critical for maintaining a safe environment during takeoff and landing.

The other ranges either fall outside this designated area or do not align with the safety protocols established for efficient checks during the cabin preparation stages. The selection of this specific range reflects established practices aimed at enhancing overall flight safety and ensuring compliance with operational standards.
