The smooth wing is to make the plane as aerodynamic as possible.<\/p>\n
\u201cSo why would Airbus install something onto their wing, disturbing the airflow? It must be really important,” Joe said.<\/p>\n
He explained: \u201cIn case of an emergency landing, let\u2019s say, on water, the flight attendants will want you to evaluate at your nearest exist and four of those exists are on top of the wings, these so-called over wing exits.<\/p>\n
\u201cOnce the door is opened, an escape slide at the rear of the wing will automatically deploy. We see the inflatable slide expand.”<\/p>\n

Captain Joe explained that because the landing is on water, the slide and wing will most likely be slippery.<\/p>\n
He went on: \u201cAirbus has installed escape ropes.\u00a0 After opening the door, one end of the rope is securely fastened to the door frame and the other needs to be attached to the little hook. Another rope is hooked up in the other hole leading towards the slide.<\/p>\n
\u201cThis little piece of metal was installed so that the escape rope can be attached, giving you a safer stand on the slippery surface on top of the wing.”<\/p>\n
