Boeing 737 Holes

Real World Aviation
1

I do not know which category to put this in, but my friend says that it is only found in Infinite Flight, not real life. I don’t know if there is a duplicate for this, but I don’t know what this is called.

Anyways, hello IFC,

My friend discovered 2 holes on the bottom of the Boeing 737 recently. He thought he ruined the 737 for me, but instead, he made me curious no I still love the 737, do these 2 holes exist in real life? If so, I would appreciate it if regular could change it to #real-world-aviation I don’t know if these exist in real life or not, just Infinite Flight.

Those are some nice retractable landing lights (I believe)

Pretty sure they’re NACA ducts. Kinda hard to tell from your picture, but I think that’s what you’re referring to.

I think they are some sort of air duct, for cabin AC, or pressurization of some sort…

I don’t know, a friend of mine took this picture and I decided to use it with his permission of course to ask the community. He made me curious about this.

These exist on a real airplane and they are called ram air inlets

As much as I dislike, Wikipedia, this gives you a brief overview of what they are:

Are they the same thing as ram air inlets, like @PhlSpotter mentioned?

11

Yes. NACA duct is essentially the actual name of the design of the intake. But yes, it is a ram air inlet.

I was referring to the 737 holes, whatever they were called, and @DeerCrusher said they were NACA ducts.

@BigBert10 You’re talking about these, right?

Hey @Krunchy_Toast, is this what you are talking about?

He was the one who brought these holes to my attention.

Those are for something else. The 787 doesent use bleed air so these vents are required.

Bleedless only implies that no air from the engine is supplied to other systems, but the 787 still uses ram air which comes in through the inlets.

21

Yes hence those inlets exist. It’s for the air conditioning systems. It’s not the same as the inlets for the B737

22

So what are the inlets on the 737 for then?
