Millions of people around the world really struggle with flying, and it’s only natural to get a little nervous in the air.

After all, even the calmest of us can get a little freaked out when we hear a weird noise at 30,000 feet, right?

Thankfully though, pilots have revealed a handy guide that explains all of the sounds you hear during a typical flight, which means you’ll never have to worry about odd noises in the air ever again.

Monarch airlines has put together a list of the weird noises that might panic you, and they’re really nothing to worry about.

The first thing you’ll hear during boarding is the airflow from the fans, circulating air around the cabin – that roar you hear is only the APU (auxiliary power unit) kicking in.

“As you take your seats you might hear noises from under the aircraft floor. This is the loading of the baggage.”


You may also hear a high pitched wine, which is the hydraulic pup under the wing closing the doors.

Once you’re all settled in your seats, you’ll hear several “bing bong” noises, which is used by cabin crew to indicate that necessary checks have been carried out – again, nothing to worry about.

Monarch say: “You will hear that same sound several times right through until disembarking, as they pass information back and forth.”

Next, there’ll be a whining noise as the slats on the wing are moved into their proper positions.

A second engine is then turned on while the plane start to taxi to the runway, which will result in a change in cabin noise.

If the second engine isn’t already running, the pilot will start it on the taxi out to the runway, creating a change in engine noise and cabin noise.

Air-con is turned off as the plane prepares for takeoff, which means the cabin will be quieter than before.

The guide then explains all the sounds of takeoff by saying: “In the forward cabin you will mainly hear engine fan noise; in the rear you will notice the roar from the exhausts.



“At the same time the pressurisation system automatically reconfigures for flight, which reduces the airflow sound in the cabin.

“There will be the occasional ‘thump-thump-thump’ as the nose wheel runs over the runway centerline lights; we try to avoid this, but it is not always possible!”

Once you’re up, there will be changes in engine noise as the plane changes altitude.

So far, so good. However, landing can be the most stressful part of flying though, and there are plenty of noises that passengers can expect to hear.

The main one is a rumbling noise. It might sound alarming, but it’s just the pilots engaging the speed brakes on the wings.

“At about five miles from landing we select the gear down. Again the wheel doors open, with resultant aerodynamic and hydraulic noise, until the gear is locked down and the emergency exit lights illuminate with a single chime,” the guide says.

“The hydraulics whine as we select landing flap. Once down, you will feel a slight buffet.”

And there you have it – all the noise you’ll experience during a flight explained. Next time you fly, nothing will take you by surprise and you’ll be more relaxed than ever before.
