RE: Identify This: Strange Approach Noise B767

Thanks everyone who shared their theories. I think Boeing767Mech came closest to having the right answer. The other day I flew into <acronym title="Sydney - Kingsford Smith International (Mascot) (SYD / YSSY), Australia - New South Wales">SYD</acronym> from <acronym title="Auckland - International (...

RE: Identify This: Strange Approach Noise B767

OK... More clues. I've been watching and listening closely for the past few days and can confirm that on four occasions I've heard the sound described originally, and when I've rushed to the window to look, it's been a Qantas B767 every single time. Twice, the sighted aircraft were banking steeply. ...

RE: Identify This: Strange Approach Noise B767

DL757MD, I guess I could try and grab a sound bite with my mobile and then upload but <acronym title="Sydney - Kingsford Smith International (Mascot) (SYD / YSSY), Australia - New South Wales">SYD</acronym> has a noise sharing policy and since I started this thread it has been strangely silent overh...

RE: Identify This: Strange Approach Noise B767

Ah huh! JetMech... you may have the winning answer! When not on the ground, 'cossetted away in the leafy, tree lined avenues of the Upper North Shore', but actually up in the air in QF767's, on approach to <acronym title="Sydney - Kingsford Smith International (Mascot) (SYD / YSSY), Australia - New ...

RE: Identify This: Strange Approach Noise B767

Hi CptSpeaking, You're right. There's no way you'd hear the noise of the motors that power the slats as they extend, over the sound of the jets, which is why I was fairly certain it must be some sort of aerodynamic noise. It's just like a sudden 'skud' sort of sound, if that makes any sense. Interes...

Identify This: Strange Approach Noise B767

I live at Wahroonga under the northern approach for Sydney Kingsford Smith's main runway so I'm a little familiar with the variations of engine sounds of different aircraft types. One sound that has me perplexed though is a strange noise that seems to be associated with B767's on approach. I would e...
