A friend of mine is a pilot and he always laughs when I tell him how scared I get. He described the engine spool down as being like joining a motorway in your car, you need to welly it a bit to get up to speed and then ease off to match the speed of the traffic. Also when I was going on about the bumps, he told me to close my eyes and imagine I was riding a dirt bike round a motocross track - it actually worked! When I have to fly - and I avoid it as much as possible - I take a look at a flight tracking app and look at just how many planes are up there at any given moment. It helps.

I thought I was the only one who thinks the plane is going down during sound #3. Glad to know its just the thrust changing and not the engine failing. Great video!

The screw jacks

One key sound you missed out after take off and approach is the flaps retracting / extending. When they retract, you definitely feel a loss of altitude and the engines increase again slightly to compensate. Also when they extended, you can feel the extra drag through the increased vibration. You can also hear the flaps extending on the ground. My house seems to be at that exact point when the flaps extend when planes come to land at Manchester in the South West to NorthEast direction.

No aircraft loses altitude with flap extension on takeoff. It would generate a Ground Proximity Warning "Don't Sink". There may be a change in thrust however. Some aircraft reduce thrust automatically with flap retraction. This is probably what you are feeling.

@chipsawdust5816

9 ай бұрын

@@ImperrfectStranger You beat me to it. Unless the flight crew are not paying attention (extremely doubtful btw) there will be no altitude loss during flap retraction. The airplane can accelerate with less drag and will continue to climb even with the same thrust setting. The feeling you have in your seat and on your body is the same as in the cockpit. Another reason why, when flying on instruments, you cannot trust your body, you have to trust the instruments completely.

Thank you so much for this video, the “slowing down” part of the engines lowering thrust always really scared me because I thought it meant the engines were failing and we would soon be gliding in silence. And the “barking” used to scare me a lot too, and I thought it was a malfunctioning plane about to take off!

Interesting video! The noise of the PTU has freaked me out in the past, but now I know what it is, so thank you! When on an A320, there was a sort of high-pitched whirring type noise from near the front of the plane that I’ve always wondered about too.

2:00 - on many airplanes there's also a "jackhammer"/"rumble strips" sound right after liftoff which causes vibration and isn't something you want to feel when you've just taken flight.

I cannot tell you how much I appreciate this video! I am one of those nervous flyers - and really it comes from a lack of understanding. I was totally thinking the plane’s engines quit working when we reached our cruising altitude! I thought we were going down … but everyone else on the plane seemed fine. The attendants seemed fine… so I realized it must be okay but there was no explanation. It would be really nice if the instructions the attendants give you is also about what to expect that is “normal” instead of everything about crashing. Again, thank you for your channel! Maybe next time I fly I will relax instead of questioning my choice to board the plane.

I’m a frequent flyer and had worked out some of the sounds. Good to know what the ‘barking sound’ is on Airbus planes. The engine slowdown did sometimes concern me though, so good to understand exactly what is happening. Good video.

Amazing explanation. You re great at clarifying situations that are at least for newbies very concerning and possibly frightening. Knowledge sets us free, thank you 😁

I used to have pretty bad anxiety while flying and still do to some extent mostly with moderate and worse turbulence. But the engines spooling down after take off used to get me nervous that we had hit a bird or something. What helped for me was playing right sims and better understanding why they do that. Now I'm ready for it and expect it as normal.

Thank you so much for this channel and the information you give us. I have always cried on take off and landing but understand how things works and what sounds are makes me more confident 😊

Well what a great video!!! Always wondered what these noises were and now I know!! This video should be used after the safety videos on all aircraft!!! Very informative

And that thud then lovely rumbling sound and vibration on approach when the landing gear goes down. I actually love it.

Thanks for all the information, and you explain everything good and clear. This should be made available for all air travellers. It's very well done indeed. ✈️🛸

Thank you for this very informative and helpful video that has, along with other similar videos, made my flying a lot more enjoyable in recent years. The one noise I have heard is whilst still stationary, maybe even whilst still at the gate, the engines would surge, seemingly to full power, then reduce again to idle. I have been told hat this is to check the take off settings, so (hopefully) the pilots would see any errors in the flight settings...Had they made any.

the last sound , the barking as you called it, I didn't know what it meant, now I do. Thank you very much for your video!!!

Very informative video, as a frequent flyer I actually take note of all the sounds & I'm fully aware what they all mean except the hydraulic pump sound...you skipped one though, the sound of the flaps extending/retracting before/immediately after take off and also during descent

Great video! most of my assumptions were correct about what the mechanical sounds were, but I had no idea what the three chimes meant. Your narration of the video was excellent.

Airplanes are machines. Machines make many different noised when they are operating. Back in the sixties, staying in a San Francisco hotel, I began to understand that hotels are also machines that make noise: heating, air conditioning, elevators, people, plumbing, people, and add in the street noises. Our hotel had a multi-level parking garage. Something was always making a noise.

3 gets me all the time! Great video Mr.Raf

I’m taking an overseas flight tomorrow, thank you for the video, every little bit helps when you’re anxious about flying!

This is the coolest video I've ever seen.....I'm serious, I always wondered what those sounds were, very cool

Thank you for the information, I’ve never flown before due to anxiety.. this puts my mind at rest a bit..

Another thing of note, sometimes atc will place speed and or altitude restrictions on planes especially in class b airspace which surrounds the vast majority of large airports frequented by big passenger airlines. This will sometimes require fairly significant engine power reductions.

@beltrams

6 ай бұрын

Agreed, sometimes in busy airspace, the climb-out can get held at an intermediate altitude, then in order to avoid overspeed, especially at lower altitudes with speed restrictions, the engines have to come back, sometimes somewhat abruptly, only to spool back up when the clearance to a higher altitude eventually comes and the climb resumes.

Good video for those who don't know these things. Not a commercial pilot myself but a pilot nonetheless, and also a mechanic who has worked on all these kinds of systems on all sorts of airplanes over 40 years. Another thing - if the airplane makes a noise it's not supposed to, the flight crew will have as much concern as anyone else on the plane. And they will almost always get a notification in the cockpit warning panel(s). You gotta trust they know what they're doing!

Its also worth noting that if you’re sat upfront you’ll hear the engines more than you would sitting behind it, as you’ll only hear the exhaust gas coming from the engine and how its overall louder in cruise than during takeoff as the airspeed makes a big white noise which drowns out the engine sounds. You should also mention how you can hear sounds like the fuel pumps (you used a 737 fuel pump noise as an example when you mentioned hydraulics) and external sounds such as brake fans and apu.

Each ding you hear is a different cue to the cabin crew. Different airlines may have more/less dings to signal to their crew when a certain phase of flight has been entered.
