Have you ever wondered about why the Airbus A320 gives out the Howling noise when it flies over you on approach? Or what that barking sound is as you have just pushed back? Maybe you have been flight-spotting and wondered about why the Boeing 737 and the Airbus A320 sound so different during takeoff?
In todays videos I will be explaining a few of these phenomenons and I think you will be surprised!

How can you resist petting your wonderful little woofers?? I've been a technical training developer, trainer and evaluator for over 35 years. Few people understand how difficult it is to simply explain complex subjects to a non-technical audience. You do a magnificent job sir. 5/5. You understand your material and target audience, and consistently maintain your discussions at that level. For those that are not professional trainers; it is VERY difficult to train technical subjects without level jumps and slipping into using technical jargon without explanations. I commend you sir for a great channel with interesting and educational content.

I don’t get it either. One of the biggest benefits I have from working at an airport is that if my supervisors or managers have been stupid and I’m now cranky, I can just go outside to the pedestrian areas of the airfield and just watch the planes takeoff and land. It isn’t long before I’m soothed back into a good mood.

[@dorisdanielsen3296]

Here's one I heard recently. From the emergency exit door, right at rotation and touch down, a loud whistling sound that rose in pitch, ending with a pop. I thought maybe it had to do with cabin air pressure and a leak in the exit door seal. I told the attendant when I disembarked.

[@MentourPilot]

That’s very likely correct!

[@Eastmarch2]

Ive heard that one before, it whistles higher and higher until it stops, I assumed that it was just the door getting seated with internal pressure until it finally seals.

[@enricomontanari1390]

The howling noise from an A320 is COOL. Looks like a jet fighter or at least something powerful

[@revenevan11]

Exactly my thoughts on it, reminds me a bit of the sound of huge capacitors charging up on something like a big pulse laser or a railgun or coilgun! The high pitched sound of that power building gives me goosebumps every time! About a month ago on my commute home from work I had the good luck to pass Cleveland's airport right as a jet (even though the highway is right next to the airport and they fly right over as they land, there are ofc way less flights these days) flew directly over me to land! My windows were down and it made that incredibly powerful noise, so now I know it was an Airbus!

[@electricheartpony]

It is a powerful machine regardless. ^.^

[@kemi242]

I'm an aviation enthusiast living near a busy airport, and I can now tell a Boeing apart from an Airbus, just by sound. Thanks. ;)

[@DCYote1]

Everyone thought I was crazy because I could tell there was an A320 overhead by the noise! Glad to know that it IS an actual thing and I'm not crazy.

[@mikoto7693]

Oh my friend you’re not crazy. I work in ground handling at my local airport and I always know what kind of aircraft is taking off without looking. I only realised I’d subconsciously learnt this when I spooked my entire team when the 787-800 landed but I had no way to see it from my position and remarked. “Oh the Dreamliner is down.” (The common name of the 787.)

[@ajg617]

I finally know what the Bus whine on approach is - thank you. I work at an airfield over which eastbound aircraft fly on approach to Boston. They typically are at 9500 or so according to FR24 so a bit higher then you mention. I finally identified the Airbus as the noise maker after repeated tracking of individual flights. Had now idea what that noise was.

Came here to learn about the PTU barking sound, but also was pleasantly surprised to see the sound I hear so often (14:07) explained. I live under one of the final approach paths for MAN about 15nm away, so I hear it pretty much daily, depending on the wind directions.

[@curtisdowney9286]

The howling sound of the A320 series is quite distinctive, where I live many of our flights are A319 or A321s. I have also noticed a howling sound (but of different tone) on CRJ-200s and Challenger jets upon landing. Good video Mentour Pilot

I really loved this video. I live near an airport, I imagine in the direction of the final approach or the take off direction. Every day I hear the engines' noises. It's a true symphony. I'll start paying attention to the noises, check if I can listen to an A320.

[@Shadowfax-1980]

On the last point about the high pitched sound that the A320’s vents make, I think it’s similar to the whistle P-51 Mustangs make when they’re doing acrobatics. Apparently, the whistling comes from air moving over the gun ports during certain angles of attack.

[@ca3340h3993]

Hello Mentour, great video as usual. One thing that wasn't covered which could worry some nervous flyers is why the engine noise, particularly in front of the engines, changes from a whine or roar into more of a 'Buzzsaw' at high power (such as takeoff and climb). My understanding is that it happens when the fan blades spin supersonic. Is that correct?

[@jonntischnabel]

I always thought the barking sound was the pilot testing the rudder. Oh well, you learn something new every day! I also live in the approach path of Manchester, and I like the howling sound, didn't realise it was only the a320 until today. 🙂

I'll give you a story, not sure if its normal or not. Happened on an easyjet a320: we were taxiing towards takeoff, an the lights randomly blinked 2 times...all of them, it just became pitch black for a moment. People looked at each other, noone said anything, I was not really worried as well, as a frequent easyjet flyer I trust them. But that was still an eerie feeling, never seen that happen before or since.

[@MentourPilot]

I’ve been on A320s that does that as well. Not sure why to be honest

[@mahumia]

I am a bit of a nervous flyer, so your videos are really great for me to understand what is going on! I used to be really afraid of flying when I was a kid (afraid of heights combined with travel sickness), but once I got on a 'testflight' for firsttime flyers it has been a lot better. (Little cityhopper going from Amsterdam to Zurich and back). Yeah sure, I still get nauseous when hit with bad turbulence and if I am not able to see an horizon when the plane takes a turn... but at least I can sit back and be comfortable most of the time.

The 737 and A320 are the only commercial jets that come into Queenstown (despite it being an intl airport...yay mountains and mad terrain), and I live not far from the end of the runway, and this clarifies how I can tell who/what's taking off or landing far more clearly than my educated guessing!

Really interesting - I'm sure the bark would have concerned me if I'd heard it LOL. More like this please! Fascinating stuff.
