These beeps let the flight crew know the plane has reached 10,000 feet. As for the thumps, that’s the landing gear retracting.ĥ Minutes After Takeoff: Two loud beeps of the same tone. The air system needs to adjust for the airflow rate and temperature changes as the plane climbs. The whooshing noise is air from the engines (the air used for the cooling and heating system) changing as the RPM of the engine increases. Takeoff: Two quick, loud thumps from under the plane, and a repeated whooshing noise that sounds like a spinning propeller. This causes routine rattles and creaks, like a house settling. Interior panels and galley components on planes have a bit of room to move around, because they can be changed out. While taxiing or flying, you may hear a lot of rattling from different components of the plane. Wind noise can indicate that the redirection is taking place.” Cox said, “Air is used to start the engines and to cool and heat the cabin. The wind noise indicates a change in the air source. The sound of heavy wind as the plane begins to taxi to the runway. The staff is closing the cargo hold door. (Often this means, please bring us coffee.)Ī light pound from under the plane, two whirring noises that sound like a drill. This is a call from the flight deck (cockpit) to the flight attendants asking them to pick up the phone. This is an intercom call, indicating that one crewmember wishes to speak to another. Here’s a non-exhaustive breakdown-by sound-of everything you’ll hear on a flight and what each of those noises means.Ģ0 Minutes Before Takeoff: Two dings in a row, the first a higher tone, repeated twice. So unless the sound you hear is the flight attendants telling you to assume a bracing position-which really only means there’s the potential for a problem-everything’s most likely O.K. Still, the unknown can be scary, so we asked Captain John Cox, a pilot who’s flown more than 14,000 hours, to help us decode all those strange airline sounds. In fact, the last time a U.S.-registered airliner had any fatalities was in 2009. You’re more likely to drown in your own bathtub than you are to perish in an out-of-control flight. Sitting in a chair that's floating in the air may be technologically stunning to some, but that floating-in-a-tin-can feeling puts some passengers on edge and sends their minds racing: Do the flight attendants look worried? What was that bump? And, oh man, what was that noise?!īut you don’t have to worry.
