What Is This On The Wing? ( OS A319)

Wed Jul 22, 2009 1:43 pm

Hi guys,

On a boring flight from HEL to VIE I noticed this 2 little parts of the wing and until the landing I could not figure out what it is good for. Honestly I never noticed it before.

Can anyone tell me what it is and what for.

Many thanks!

See below:

Additional question: Is the marking of the flap position usual?

The yellow loops are for anchoring the life rafts after a ditching. After the raft was full of passengers, you would cut yourself away with the knife that comes with the raft.

I'm sure they were utilized in the Hudson ditching. (Would that be a first?)

Well I have no idea what those things are for, maybe for mechanic checks? A D check where they take everything apart maybe that's how they hold the wings? As for the flap markings I have seen them before. I am guessing they are for MX and pilots to know where the flaps are in case there is a malfunction with the indicator.

I think that the these yellow anchor point is used for an escape rope. there is an escape rope located a small overhead bin above the overwing exits. When the overwing exit is removed there is an anchor point on the structure, the other end been on the wing.

Life rafts mainly, but I have seen them used as anchor points for mechanics safety harness, when you are working close to the trailing or leading edge with some or all of the flight controls removed. For the most part they are there for the mechanics to trip over when working on the wing.  Big grin

The airplane is usually on jacks during heavy checks, and if there is major structural work being done usually the fuselage is jigged, and jacks in place so nothing moves.

The number marks are to verify wing flap position visually should there be some problem with the electronic position indicator. Most planes have something like this as well as the anchor rings for the ditching ropes.

Thank you. I read it but I can´t see most of the pics so I was not sure if it was about the same.

The Lift raft anchor point is common.But is the TE Flap marking in units common too on all aircraft of the same type.

Wirelock is correct.

I fly on the 319/320 and none in our fleet have escape ropes at the over wings. The hooks are actually used if the overwing exit slide deflates during an evacuation. There is a clasp on the slide which is hooked into the attaching point on the wing. This holds the horizontal part of the slide that sits on on the wing taught, and four passengers on the ground hold out the sloping part of the slide allowing the slide to still be used to evacuate passengers.
