There are some "markings" over the wings and the horizontal stabilizer. Could somebody explain what they are?


  • $\begingroup$ Note, these markings are not restricted to the A380. Almost all commercial aircraft in similar shape have these markings on their flight control surfaces. $\endgroup$ Feb 7, 2016 at 11:48

The darker areas denote where it is safe to step. Stepping outside of these areas could cause damage to the aircraft.

Here's a closeup of the warning: Quantas Flight 32 Wing

(This happens to be a photo of Qantas Flight 32 after its un-contained engine failure)

    $\begingroup$ New bottom-tier Ryanair ticket. In all seriousness, maintenance personnel are the most likely people to have to heed this warning. $\endgroup$ Feb 7, 2016 at 21:41

    $\begingroup$ So the warning is printed both ways so it can be read by those already walking outside the allowed area? $\endgroup$
