The 767 Howl

Wed Mar 20, 2002 5:18 pm

Lately, the AA 767 from JFK has been coming here to SJC...and every day when it comes in at around 11:30am, I run to that AA gate and watch it dock. That plane is amazing...but one thing that I especially love is the howl the engines make as it lightly gains power to glide into the gate....does anybody know that noise I'm talking about? Sounds like the captain applies power slightly, then eases off and repeats that till he gets the correct speed into the gate..but this sound gives me chills, it's like a sound of raw power!

I know EXACTLY the sound you mean too SJC.
Sadly we don't hear it at our local anymore since Air NZ and Qantas pulled their 767s out of here.
But I noticed the same sound last month when we had a BA 777 visit with RR Trent engines.
I'm trying to get the same sound on my Flight Simulator 767s but haven't found it yet.

I've never heard that "howl" (or hum?) on any other type; mind you, we don't get much here (NZWN).
We're just a small international (more like regional) airport.

I know the sound that you speak of!!!!!!! Very, very cool. On occasion, I will notice that a 757 will make it's own version of that sound as well. Although my favorite is still that "growl" it makes on takeoff. Most widebodies make this sound, but the 'ole "diesel-10's" do it the best.

Yep I guess I know what you mean...also , when the engines spool up on takeoff , the plastic parts of the cabin start "vibrating" in a very damp noise...
When I joined A.net it was still free, haha ;).

Hey Boeing nut!
I know that "growl" you're talking about too...lol.
And it's true; the DC10s did do it the best.
As a kid growing up in Auckland, I always used to go outside at 9:15pm just to hear that sound from the nightly Continental DC10 to Honolulu and LA as it flew over my house.

I know that sound you're talking about, and like the other's have said, the DC10's have a very distinct growl when you take off, but you have to sit forward of the engine to hear it in the plane. But that 767 sound is awesome!

I find that I hear this howl from any aircraft with Trents. I've heard it from AC's A330's, and TS B757 when spotting at YYZ.

I dont think he is talking about that Whinny sound most large turbofans make at full power. He is talking about that "Woosh' sound that the GE's make when you apply a decent amount of power. You can alo hear it on approach when a GE powered 767, the pilot applies a little power. The RR 777 makes that sound as well when they apply a little power during taxi or in flight.

ATA L-1011,

Your "whinny" is our "growl", and your "whoosh" is our "howl".  Smile/happy/getting dizzy I think the sound that SJCguy is referring to is the "brake away" thrust. Either way, it's a freakin cool sound!!

Well boeing i dont think he was referring to a takeoff growl if you read the post, just a taxi. By the way it doesnt matter!

That's the sound on the CF6-80A2 engined 763s and CF6-80A 762s. I am partial to the CF6-80C2B6F powered 763ER, myself. Now that engine sounds sweet.
It's a new day. Every moment matters. Now, more than ever.

I love that sound too!. Hey SJCguy starting 4/7/02 you can hear that sound twice daily. The other JFK flight will go to a 762 also!

Yeah, we meant the "howl" sound when it's taxiing.
Sounds like the ghost noises I used to make to my little cousins as a kid. Big grin

Yep the 767 does make a very distinct kind of sound- especially the 767-300. On approach they make a howling sound like no other plane and i know it's a 767 just by the sound it makes going past. I also hear that "whoosh" sound when more power is applied to the engines on final. I flew on a 737-800 the other day and on take-off/climb the engines produced a very loud "chainsaw" type sound. I was sitting in front of the engines so maybe this is why i heard it?? It's similar to the sound an A320 makes on take-off anyone know what i mean?

The 767 Howl

Thu Mar 21, 2002 9:50 pm

When a 767-300 comes in at our airport on this certain gate, it's got to make a sharp turn and the pilot needs that extra boost of power to complete the turn.

Not only do those CF6s make that incredible sound, but they really kick up some sand and debris from behind the plane and blow it back several hundred feet.

I think the DC-10 sounds pretty cool too, it's got that high-pitched sound.

Yes, I know the A320 chainsaw sound well. I think you only hear it fore of the engines, but not sure. I always think that it's going to be a really noisy flight, then it just gradually fades. I have always planned on listening really closely to try and establish just exactly when it disappears, but I always forgot. Now there's no A320s flying in Oz, so I guess it will be some time before I hear it again. Damn!

Just one more reason why the 767 is my favorite plane.
