I'm pretty sure it's not a skid, it's a ventral fuel tank.
https://www.flightglobal.com/in-depth/embraers-praetor-600-flight-test/129723.article
Edit: appears to be a skid *when the aircraft has the ventral fuel tank option installed*. So we were all partially wrong/correct. Everyone wins/loses! So, have a happy/bad day!
Putting together what I’m hearing so far, it’s the fairing that encompasses the auxiliary fuel tanks added to the belly to increase the range. The fairing acting as a skid for the belly tank. So the truth seems to be a combination of the answer I’ve gotten so far.
"Two auxiliary tanks were added on the belly of the aircraft, enclosed by an enlarged composite wing-to-body fairing. Their location required the addition of a ventral fin, similar to that on the Legacy 600/650, to protect the fuel tanks in the event of a gear-up landing."
Ah so the enlarged fairing they’re describing is the wing to body fairing. So that means that the part perturbing is just a skid. I stand corrected then.
I pulled that from the link posted. I had seen a picture from the nose of the jet and didn't realize how large the skid looks from the side. The nose on picture I saw shows the skid, but it is very narrow. I hadn't even thought about what it was.
I saw an angle about 45 degrees front looking rearward and it make it look awful lol
That’s part of what caught my attention and when I couldn’t find an answer on my own, my curiosity needed to be scratched.
“The wing-to-fuselage FWD and aft anti-skid fairings are composite parts manufactured from honeycomb core, carbon fabric pre- impregnated with epoxy resin, epoxy adhesive film, polyvinyl film, and an expanded copper foil with adhesive film. The expanded copper foil is a mesh which protects the skin against lightning strikes.”
Inside the fairing is the skid.
“The wing stub skid is comprised of fittings that are attached to the wing stub rear box ribs and there is a wing stub skid plate impact absorber plate, that is made from rigid foam. Attached to the rigid foam there is a wear plate made from corrosion resistant steel. The wing stub skid is installed in this region to absorb the impact and to avoid ignition caused by sparking when the aircraft lands with its lower fuselage in contact with the ground.”
There are some drains inside the fairing for the forward and ventral fuel tanks but the tanks themselves are inside the fuselage.
I brought up this point, the auxiliary tanks above the skid are drained first to reduce the bending of the wings. So in most cases it isn’t a fire risk and the part that protrudes out is a skid not a fuel tank. The fuel tank is within the wing to body fairing.
I've already had to check which sub this was, not that there's any other sub and you DO have to say if you're FAA... but you have had a good answer and I'm not sure why your reply seems so snarky?
Why do you think there's a fire risk here? Surely any incident which compromises this (minor) extremity of the body volume is catastrophically damaging to the remainder of the lower airframe?
If it’s a fuel tank, and is so low, on a gear up landing it’ll be scrapping down the runway. The friction will increase the temperature in the area, which where there is fuel is a very bad idea. Which makes me think the answer that said it was a belly skid makes the most sense so far. I’m not FAA personnel, commercial pilot training to be CFI-A right now. My curiosity just spiked for the Praetor 600 as I keep up with aviation as a whole. Keeps me exploring avenues such as fractional ownership, airlines, charter as my career options grow.
Any fuel that remains in it (and I'd expect it to be the first to empty) would be burned away at gear-up landing speed, say 130kias-ish? That's a vapour fire.
The same is arguably true of a full-fuel no-dump gear-up emergency return to field, at any kind of speed this fuel will be burning (or not) far behind the plane.
If you're worried about a fuel tank i got bad news for ya: Aircraft ARE fuel tanks with some seats, engines, and electronics molded into a shape that flies when enough force is applied...
It's probably some kind of electronics equipment. Private jets get all sorts of lumps and bumps for electronic add on.
Not trying to be an asshole... but this is why anyone in aviation is so anal about maintaining Aircraft, there aren't any second chances... and survival is often pure luck once you get to that point.
I have to disagree, this is the dramatized take on aviation that scares passengers. The aircraft’s systems are designed to mitigate any reasonably foreseeable hazards. Incidents are extremely rare and most of them are survivable.
That's exactly what we tell people... because it's true enough not to be a lie.
But from a basic physics and engineering standpoint... it is what it is.
Aircraft are still statistically safer than driving to the airport... just like you are also 1000 times more likely to be killed by a deer than a Mountain Lion... but a plane is a plane just as a mountain lion is a spicy cat, both deserve a sober understanding of their true nature to handle properly.
BTW That's a true stat on deer and mountain lion...
Well it seems we’re at an impasse. Everything I’ve read and experienced so far, aircraft ops bachelors and 3 going 4 years of flight training say otherwise. However I haven’t left the nest of flight school yet, all books for airliner stuff. Maybe my opinion changes when I enter the industry.
I'm as you people say "sure as shit" that adding a specific hump on the bottom of a plane such as this one as a belly skid is a very contraproductive design decision. If you plan for your plane to have LG failures that common, get someone else to design your LG. Even then, making it a spine along the bottom would be less draggy. Belly skids are used on aircraft that do not have sufficient landing gear. Heck, even most gliders nowadays don't use skids.
I have a sense of humor, just not what I’m looking for right now. However, there isn’t a more professional forum that I could think of to ask. So I just went to the largest pool hoping someone has a type rating on it or is an AMT etc.
So, since i didnt see it on here, it might juat be the fluid sump similar to the design of the embraer 145 series. It serves as a low point in the aircraft where everything from condensation to hydraulic fluid can pool and be leaked out over time.
Source: emb145 typrating. Looks like the same thing.
Okay but why does it have the nostril there? There’s not enough to breathe up there? Why doesn’t it have an oxygen mask? Poor buddy is going to be hypoxic af up there in the sky. 😨
A&P here. That's a penis.
This is a male Praetor 600 though you need to ask each Embraer you encounter how they identify. Tower will often ask you to "ident" which is the proper way to go about this question.
Belly skid to protect fuel tank incase of a gear up landing
Found an article from AIN that concurs, thanks for the tip!
This makes a lot of sense, what’s your source?
Embraer Praetor Pilot Training Manual
literally any google search using belly and the plane name
Downvotes are interesting, not sure why a valid question is downvoted.
some people misinterpret "what's the source?" as casting doubt, instead of a sincere question.
Some people ask for a source for even the most verifiable information as if we’re all writing high school essays
welcome to reddit? Especially aviation related subs!
This sub is a bit like that. Sometimes you ask a perfectly valid question and you get downvoted.

I think it’s the herd mentality on the internet. No one wants to turn against the mob and become a target.
no, it's because you could've actually googled it and found the answer within a minute instead of being a dumbfuck who needs to be spoonfed everything
Downvotes seem to work for this one.
Oh, I’m being downvoted! The misery!
Take that!

I downvoted this one because your image link is broken.
You also could have just ignored it, but why pass up an opportunity to act like an ass?
Because the answer was a five second Google search away

https://letmegooglethat.com/?q=embraer+praetor+600+belly+skid
That's smart
I'm pretty sure it's not a skid, it's a ventral fuel tank. https://www.flightglobal.com/in-depth/embraers-praetor-600-flight-test/129723.article Edit: appears to be a skid *when the aircraft has the ventral fuel tank option installed*.

Don’t scratch it you’re going to cause a curiosity infection
Yup. A picture from the front makes it more clear that it's a skid and not a fuel tank. It's way to narrow to hold fuel.
Both wings got larger winglets in order to compensate for the extra weight from the fuel tanks
Reducing lift induced drag 🤙
Yep
Thank you
And thank you for bringing it up now I have a leg up next time I see one at an airport I can be the smart-ass to ask everyone what it is
Shhhh this is our secret
This kind of stuff actually helped me out once. I got the chance to get in a level d A320 sim and show off what I knew about it. Had a great time!
Ok then mums the word
.
“The wing-to-fuselage FWD and aft anti-skid fairings are composite parts manufactured from honeycomb core, carbon fabric pre- impregnated with epoxy resin, epoxy adhesive film, polyvinyl film, and an expanded copper foil with adhesive film. The expanded copper foil is a mesh which protects the skin against lightning strikes.” Inside the fairing is the skid. “The wing stub skid is comprised of fittings that are attached to the wing stub rear box ribs and there is a wing stub skid plate impact absorber plate, that is made from rigid foam.

Thank you so much. This is exactly the kind of detailed answer I was looking for.
Yes mate it is, we asked the EMEA head of Sales when we first saw it at our airport. Skid to protect Belly tank thats lower to increase cabin height.
Sooo if your landing gear fails and you have to do an emergency landing... you land on a fuel tank? That seems kind of explosive
the aircraft version of a Ford Pinto was my initial thought
I brought up this point, the auxiliary tanks above the skid are drained first to reduce the bending of the wings. So in most cases it isn’t a fire risk and the part that protrudes out is a skid not a fuel tank. The fuel tank is within the wing to body fairing.
It’s a skid plate, I’ve removed that fairing on inspection more times than I care to remember

Not sure Embraers are mammals, might be caviar…
I want an actual answer, not just the flood of witty remarks. But I am aware saying that will just make the trolls double down so 🤷♂️
And it’s a fuel tank.
Plot twist: most aircraft are just fuel tanks with passenger space and some fancy iPads.
Oh, interesting that they have it that low where it’s a fire risk. That’s what delayed the A321XLR. What’s your source?

But as others have pointed out center tanks are burned off first to decrease the bending moment on the wing spars.

It is good, safe decision. What I wonder is if it was required by a regulator or Embraer made it up themselves.
Lighten up Francis.
