Advice please. Are the black lines walkways

Are the black lines on this Boeing 777 non slip walk ways. Or do they serve some other purpose. A PPL friend of mine wishes to know and I can’t answer him.
Thanks for your time and trouble.
Be lucky

Link/image doesn't seem to work. Best to use Go Advanced/Preview Post first.

As a general rule (not specific to the 777), most airliner types have areas delineated on the wing to show where you can and can't walk.

So many things wrong here!
blob: isn't part of the url, get rid of it.
Neither url you tried to post is an image file.
Your link should look something like https://website.com/filelocation/file.jpg
For that matter your links are invalid and don't appear to go anywhere.

I don't think it's meant to be a link, but an uploaded image embedded in the post.

In which case the URL ought to look something like this:

Code:

https://cimg1.ibsrv.net/gimg/pprune....0a93575041.jpg

i.e. pointing to a previously uploaded file.

I have failed in my attempts to post the photo by cut and paste. MODS please delete this thread. It is pointless without the image.

Again, haven't seen the picture. Lines can have indicate different things. On the 737NG for example they can show the area of the wing where cold soaked fuel frost can form without a need to deice, on other airplanes it is the area you can step on (it is not non slip though). If it delineates the area to use for evacuation it usually is explained in the safety card.

That’s the one. Outboard of the marked walkway.
Thank you Sir.

The 200 models, being shorter, don't have this system and so do not (I think!) have the black lines.

And of course the -200s don't have the wing markings associated with the overwing emergency exits either.

David, this black line, when viewed from the horizontal stabiliser-mounted ground maneouvre camera system, indicates the approximate position of the maingear outer wheel under the wing if it cannot be seen in low vis conditions. This is helpful on tight taxiways, corners, etc.
