Ryanair Initial Practice Exam

During severe turbulence, one of the critical actions that crew members must take is to ensure the safety of passengers and to minimize the risk of injury. This is why the correct answer is to fasten all seatbelts. When turbulence reaches a severe level, it can cause sudden and violent movements of the aircraft, which could lead to passengers being thrown around if they are not properly secured.

By instructing passengers to fasten their seatbelts, the crew is reinforcing safety protocols designed to protect everyone on board. This action helps reduce the likelihood of injuries occurring due to the turbulence and provides a secure environment until the turbulence passes.

Other actions, such as securing trolleys in place or making announcements, are important but do not directly contribute to passenger safety in the immediate context of severe turbulence as firmly as ensuring that everyone is buckled in.
