The Secret Sounds Planes Make… Revealed!
ST. PAUL, MN – Flying can be a bit nerve-wracking, especially when you’re not familiar with the noises airplanes make. Here’s a guide to help you understand the most common sounds you might hear during a flight.
Whirring Noises Before Takeoff
Before the plane takes off, you might hear a whirring sound. This is the aircraft’s flaps extending. Flaps are panels on the wings that change the wing’s shape, providing more lift at lower speeds, which helps the plane take off. You can see the flaps moving if you look out the window. The whirring noise occurs again as the flaps retract after takeoff and extend before landing.
Rhythmic Bumps on the Runway
During takeoff, you may notice a series of rhythmic bumps. These bumps are caused by the nose wheel rolling over the runway’s centerline lights. This noise indicates the plane is perfectly centered on the runway. The bumps stop once the plane’s wheels leave the ground.

Rumble and Thud After Takeoff
Shortly after takeoff, you’ll hear a rumbling sound followed by a thud. This noise is the landing gear retracting into the aircraft. The initial rumble is the wheels being pulled up, followed by a thud as the bay doors close. You might also feel a series of rattles, which are the snubbers stopping the tires from spinning in their wells.
Engine “Powering Down”
Once the plane is airborne, it might sound like the engines are reducing power. This is normal. After takeoff, the engines decrease to “climb power” to conserve fuel and comply with speed restrictions. The plane is not losing power; it’s just not climbing as rapidly.

Various Dings
During your flight, you will hear different dings or chimes. These sounds are part of the crew’s communication system. For example, a double ding indicates it’s safe for flight attendants to leave their seats and start their duties. A single ding is often used to signal passengers about the fasten-seatbelt sign. Each airline has its unique set of dings, so patterns may vary.
Mechanical “Barking”
If you hear a barking sound, especially on Airbus aircraft, don’t worry. This noise comes from the Power Transfer Unit, which manages hydraulic power between systems. While it might sound odd, it’s a normal part of the plane’s operations.

Thud and Rumble During Landing
As the plane prepares to land, you’ll hear the landing gear extend, producing a thud and a rush of air. This is the drag created by the landing gear. The sounds and sensations are the reverse of what you heard during takeoff.
When to Speak Up
Most airplane sounds are routine and not a cause for concern. However, if you ever feel uneasy about a noise, it’s okay to ask a flight attendant for reassurance. They can check with the pilots if needed, to ensure everything is running smoothly.
Understanding these noises can make your flight more comfortable and less stressful. Next time you fly, you’ll know exactly what’s happening when you hear these sounds. Happy travels!
