It's frankly starting to freak me out a bit, as well as being really annoying as it's extremely loud.

And today, it's every ten minutes!

Does anyone notice this too? Does anyone know what it is? I tried calling the non emergency police number and they had no idea.

I'm just an armchair aviation enthusiast, and this will be a long reply, so take this with a grain of salt:

If these "low flying" planes are taking off from/departing RDU, heading in a northeasterly direction (the main runways are aligned in a n/ne to s/southwesterly direction) over your house, then as others said it could just be more planes with the growth in our area-- airlines adding flights.
And during takeoff, once they're climbing out of the runway alignment, they can turn and set their route toward their destination, which could bring them more over your house, depending on their destination. Maybe more routes were added that, drectionally, would take more planes over your house.

If these aircraft are on approach, heading ***into RDU, (heading in a southwesterly direction) it's unlikely that they're flying any lower than planes normally do into RDU. The instrument landing systems and "glide slope" (proper altitude of the plane relative to the threshold of the runway) don't change much. E.g. Altitude of approaching aircraft remains close to the same all the time.

I wonder if, with our gusty weather lately if some jets approaching RDU are keeping their engines spooled up to a higher thrust setting, to be sure they stay above the glide slope, against any sudden gusts or downdrafts ??? This would make them sound a lot louder.

In calmer weather, some jets approach an airport with their throttles pulled back more toward flight idle, or a low thrust setting. But i think, when the wind is variable and gusty, it'd be good to keep jet engines spooled high enough to respond quickly to further changes in lift / downward gusts.

Also, being this is N Raleigh/Rolesville, if these planes are on approach to RDU, they're probably still on their Base approach, meaning they haven't yet turned onto their final alignment with the runway, so, depending on where they're coming from, they might line up for final from a different vector / route, that takes them over your house.

Just my two (or three) cents.

Yes, all of them are small planes.

Omg....for the THIRD TIME. I did NOT CALL 911. I called the non emergency number, the one you are supposed to use when you have a non emergency concern. I was concerned that I was hearing and seeing an inordinate amount of single engine planes flying overhead that day, and wondered if it was because of some event or commemoration or something.
It sounds to me you may be the one with a bit of anxiety my friend.

Well thank you for a very concise and polite response. That could very well be it. Appreciate your input.

First hardly any of what he posted makes sense and second for some reason you refuse to acknowledge the small airplanes you are seeing over Rolesville most likely aren't headed into or out of RDU - there is a nice airport up in Youngsville/Louisburg that handles a lot of smaller GA airplanes which would explain why they were lower over you in that area.

People keep focusing on large airplanes even though you inferred it from the beginning and finally said it on one of your last posts that what you are seeing are smaller light GA planes which is what I was figuring from the start.

The police can't do anything about this, your best bet if you are truly concerned is to contact the FAA. Note, this should be used for airplanes "buzzing" buildings (ie extremely close to the ground) or operating in a reckless manner not doing what you described.

https://www.faa.gov/about/office_org...ia/nlowfly.pdf

There is more boat traffic on the lake for the same reasons you're seeing more airplanes now. I echo the comments of why are you so concerned? Do you call the police when you see more car traffic on a particular day? The people operating these small airplanes are private citizens just like you.

I didn't say you called 911, but you did call the police. You said it was freaking you out. I'm just trying to figure out why.

No need to get so defensive. I'm just attempting to understand what was freaking you out.

Default That's a good clarification.

I was envisioning larger, jet aircraft in my rather long (but appreciated) response!
Best.

Oh, this is in Rolesville? It must be cropdusters, then.

jeepers. I'm sorry that small planes are causing you such concern. They fly lower, on different paths, but at MUCH lower noise than commercial aircraft. Whether they're going to RDU General Aviation or numerous small airports sprinkled about is very different too.

The cloud cover/ceiling, wind patterns, etc have more effect on the big, noticeable planes. While RDU is oriented on a NE/SW axis, I see a LOT of smaller planes approaching and leaving more east/west, which coincide which going over my house near Crabtree. I've never worried about it.

No way are there arrivals at RDU every 10 minutes....the airport has two terminals and one of them is mostly empty (full disclosure; it's been over two years since I've flown out of RDU so this may no longer be the case).

Must be something else.
