British Airways has released a new YouTube video explaining how its evacuation slides work.

The video features one of the carrier’s Gatwick-based aircraft deploying an evacuation slide in just six seconds.

The B777-200 has a total of eight slides, which can measure up to 14 metres in length.

BA said that the slides’ systems are checked “on an almost daily basis”, and that “The airline’s highly trained engineers also frequently ‘blow’ the slides to ensure they work properly”.

During the video BA licensed engineer Peter Dyer also explains cabin crew terms such as “doors to automatic” or “manual”, and “cross check”, relating to door positioning prior to take off and landing.
