Entering convective weather? Put the seat belt signs on

04 Jan 2022
On 15 August 2019, an aircraft descending towards destination Beijing received ATC approval for convective weather avoidance but this was then modified with both a new track requirement and a request to descend which diminished its effectiveness. A very brief encounter with violent turbulence followed but as the seat belt signs had not been proactively switched on, the cabin was not secured and two passengers sustained serious injuries and two cabin crew sustained minor injuries. The Investigation noted that weather deviation requests could usefully be accompanied by an indication of how long they were required for.
