I recently had the pleasure of travelling a medium haul stretch in a Latin American owned / operated A320 and I noticed that 1 of the aerodynamic parts under the wing (don´t know their technical name, sorry!) vibrated excessively while the one next to it hardly moved.
With "parts" I mean the oval pieces suspended from the wing that are obviously shown in the picture below.
Shouldn't they vibrate the same throughout?
Furthermore, they both have these "antenna-like" bits at the end, what are they for please?
The angle of the one on the right is definitely "out", does this matter?
If I sound ignorant I don´t argue, but please look at it this way:
"To be an aviation expert lurking around on sites like this means educating others is one of your core responsibilities". Consider it a good deed.
I don´t work in aviation and am just interested to learn a lot more about it!
Any constructive comments are more than welcome!
