My parents were returning on a 737-300 Easyjet flight earlier today. Whilst crossing the English channel, (i realise that isnt approach yet!), my parents noticed a small round thing hanging down from underneath the wing on the furthes out spoiler thing that is underneath the wing. Forgive me, I cant remember what those big pieces of metal are called, but you know them, I think the 777 has 3 or 4, and the A310 has 3, and A300 i think has 4.
This small thing was on the 3rd one, (furthest one out on the wing). Does anyone know what it was?

Nah, theyre right. The landing light is the little sticking out bit right, and the flap track fairing is the thing which the landing light sticks out of, and there are 3 flap track fairings on a 733. Right?

Yes, it is indeed a landing light- and a very bright one too. And that hangy-down thing is a flap track fairing, just to add my name to the pile of people who are correct! I ti scommonly called a canoe. The one on the back of the engine does not move with the flaps, although on other airplanes it does.

We've got some real aviation experts on this forum!
Cedarjet's got it, those "pods" house motors that drive the flaps up and down.
Actually there are no 'motors' in the pods. There is a hydraulic motor on the aft wall of the landing gear bay that drives a torque tube. The tube is connected to a transmission at the fwd end of the pod. This drives a jackscrew that moves the flap along the track.
