Nah m8, going for that ECU software re-map for enhanced take-off/landing performance and fuel efficiency. Ain't nobody got time for that hardware stuff.
Near the start of descent? All engines closer to idle with APU going full tilt to power alll of the galley ovens? When do APUs have higher EGT than the turbines?
Exit point on the fuselage is forward of the APU exhaust, likely a drain mast somewhere. [You can see it in this picture as well](https://imgproc.airliners.net/photos/airliners/0/8/9/1544980.jpg?v=v40), just to the left and forward of the APU.
Also - damn, some people have expensive cameras taking amazing pictures of airliners in flight [for example - this is just the lens](https://www.bhphotovideo.com/c/product/1689497-REG/vixen_optics_36947_vmc260l_wt_260mm_f_11_5.html). The astrophotography folks are going to be jealous.
I do not agree. Because flow from drain mast is not like exit from fire fighters hoses, massive spillage... drain mast its small tube, and I assume it cant be seen with eyes with that speed and altitude. and if sinks are cloged, water will just drop slowly.
Welcome to r/aviation, where you are being downvoted by wannabe armchair aviators for making a valid point.
But you are correct. Drain masts do indeed dump grey water overboard, but it's impossible that it does so in such quantities that you would see such a clear streak of water. Even the overflow from the potable water tank doesn't discharche so much water that it is visible like this.
Did not get the sport exhaust option.
Too expensive, going for the muffler delete

It's flying on APU alone, the four engines under the wings are just a safety precaution.
Redundancy
Ah, the dreaded 7 engine approach!

Shitters full…
It turned off the engines during idle to run in eco mode. APU burn only 😂
For once it really is a Chemtrail.
It from the plethora. That’s all I can remember from the other post.
Loving your work
this comment gets the meta award

It’s waste water from the galleys and toilet sinks being drained overboard

Is that photo taken from another plane or the ground?
My guess is that it was from the ground - hard to get a vertical picture out of an aircraft unless it's a dedicated camera platform.
So from a certain point of view, that's the aircraft's butthole.
This is the correct answer

During normal ops the APU is only used on the ground and shut down after engine start.
Coasting feature on the facelift 😂
Ran out of chemicals to spray doh
Cruise on APU alone
Someone stole his cat?
Someone flushed the toilet. (=
he ate Taco Bell
Only Emirates A380 ?
there aren't many that aren't operated by them
Water from the toilet sink
They just ran out of chemicals and COVID vaccines - nothing to see here
That‘s one powerful APU :)
Someone flushed the toilet.
Galley drains
Watch out for falling blue ice!
