This question comes up from time to time, but I haven’t been able to find an answer.
Why do many A321s have the number 2 written on the wing flaps? I can’t find a pic, but almost any Youtube video I’ve seen that includes the wingview during landing has them.
Does anyone in here know by chance?
I believe those are not "2"s but rather sling attachment points. Probably used during airframe inspection or maintenance where the flap must be removed. I am not certain however.
Can you provide a picture maybe?
You may be seeing the the tethering brackets for the over-wing emergency exit slides.
Ah, I see now. Looks like maintenance panel indicators for the a321 secondary flap track fairings.
You can see the plastic cap, protecting a thread to put in a hook above the placard. It is not to lift up the aircraft, it must be for the flap removal, installation process.
Always the one with the pictures to the rescue!
