Airplane sounds are scary for every traveler. Have you ever wonder why your airplane was making that sound? If you want to be in control and you tend to worry when you fly, these pieces of information we prepared for you will make you feel more comfortable in the airplane.
The Bing-Bong sounds
Bing-bong sounds are used pretty often by the pilots and flight attendants to communicate, whether that’s to simply inform each other of something that’s going on – like that takeoff or landing is imminent, or that the plane has reached the altitude where the first drinks round can begin.
When you hear this sound, you should relax and order your favorite drink.
A change in the amount of noise (and wind)
The amount of air blowing through the vents above your head can vary depending on whether either the power of the aircraft or the air itself is needed for other things as the systems on airplanes are interlinked.
Since the atmosphere inside is kept at 6000-8000ft even when you’re 40,000ft in the sky, this might be when pressurizing the cabin or it could be in preparation for takeoff, or when the plane climbs.
It could also be a change in the source of electrical power the plane is using.
Don’t get worried by the flickering lights
Don’t worry if the lights flicker, this is usually the result of changing the source of electrical power the aircraft uses, especially on older planes.
That source is usually either power from the engines, power from the auxiliary power unit (the APU, a sort of generator at the back of the plane), or ground power when parked.
Nothing to worry about, this is just the pilots getting the plane ready to go or parking it up or you might also hear the sound of fans or other systems spinning up or down.
Don’t be alarmed if you hear the overhead bins shaking about a bit
Don’t be alarmed if you hear the overhead bins shaking about a bit, especially on takeoff and landing or during turbulence. They’re designed to shake around a little bit and they’ll be perfectly fine. Just be careful to place your luggage safely and keep an eye out for fallen luggage.
Roaring noise at the back of the plane
Do you remember the info about APU? You may well hear the roar of what is usually a mini-turbine engine that adds extra power to the plane if you’re seated at the very back of the plane, or boarding from the back via stairs.
Different bumps on the runway
You hear different bumps on the runway. Don’t get alarmed! It’s either the joins between the sections of the runway, which like bridges are designed to expand and contract with heat or cold, or it’s the wheels rolling over the lights on the runway.
Now that you have a little guide to thumps and bumps on the airplane, you may feel more in control and safe. As you have seen, there is nothing to worry about.
