Speed tape. Very expensive but basically helps with drag and isn’t structural.

like the flame stickers on my car
Everyone knows the red goes faster
Waaaaarrrggh!
What do we need?
MOAR DAKKA!!
ooh yeah, speeeeed holes
Yup, it's just aluminum foil with an adhesive.
Worked in an mro so mostly was removing speed tape, but occasionally we would send a bird out of a heavy check with speed tape on.
So it’s the same tape used for ductwork?
What purpose does it serve in this case?
My understanding for hvac ducting is that it…. Stays on forever? Probably the metal layer prevents the adhesive from breaking down..? Actually I have no idea..
To the internet I go!
No it's not at all.
It's literally an aluminum sheet, it will slice your hand open.
One of the most common uses is when you remove something like a fairing or a panel, to access something else, when you put the panel back on there are gaps between them. They are not structural, but it does hurt the aerodynamics of the plane, affecting the fuel mileage and cosmetics.
The solution is sealant in the panel gaps, this helps prevent moisture from seeping, and improves aerodynamics.
The issue is that the sealant takes a long time to cure properly, and when it isn't fully cured, it will splatter everywhere (I've seen this happen). A common scenario as an example is, putting the final panels back on after an inspection, it's nighttime in the winter, the sealant isn't curing, instead of the plane sitting idle for 48 hours while sealant cures, you can just put speed tape over it, the tape holds the sealant in place while it cures and then mechanics can take the tape of after it's fully cured.
Please bring us your findings!
So I looked.
The long and short of it is that HVAC tape has stronger and more temp resistant (see also: gooey) adhesives. The foil or composite layer on the outside does act to protect the adhesive, but it also serves to create an impenetrable barrier for moisture and air that is rigid and not prone to flex with increased air movement. This is valuable in systems that create a mild vacuum when kicking on, or where the air being pushed could create holes for air to move through.
It’s sort of not “one reason”, but a handful of reasons that work in tandem.
No idea what purpose it serves on an airplane tho.
It's used for very minor repairs, in this case, a more permanent repair is under the tape, but is likely curing, so they slap some speed tape on it.
Speed tape never holds anything down, it's just used to smooth over a surface, to allow better air flow.
Whatever is being covered by the speed tape will likely see more attention from maintenance later.

No items. Fox only.

Well I mean, at least it's not a Boeing
If you put that on a Boeing, would it cancel out and result in a plane that never lands?
Reality might collapse.
It might be a quick event, or a long withering on the vine...
They should probably put curtains or something up on the few windows by the wing so people don’t panic
(FYI, this isn’t bad it’s a special tape to prevent drag, and the plain isn’t actually damaged)
Looks more like Lylat to me

"your father helped me like that too"
"Follow me, Fox!"
That's speed tape ffs
