In-flight chimes can be heard during take off and landing, and this is deemed to be the most dangerous part of flying.
Airline crew members have lots of responsibilities when it comes to being in the air and one of them is knowing what the different chimes mean and acting upon them.
One flight attendant revealed that different chimes mean different things on different aircrafts but they all have general meanings.
Those chimes that you can hear throughout the first and last stages of flying let cabin crew members know that the most dangerous parts of the journey are over.
However communication between the crew becomes more secretive and serious if anyone tries to get in the cockpit while in the air.
The flight attendant said: “There is certain ways you are suppose to communicate with the cockpit during flight, especially if there is a flight attendant trying to get in or a pilot trying to get out.
“A breach of the cockpit is pretty much the worst thing that can happen during the flight.”
A retired airline captain known as John Cox explained how many chimes are expected for different things.
It’s more of a concern when there are three or even four chimes heard in a row.
Three or more chimes indicates a more serious issue, such as a very sick passenger or an expecting rough patch is ahead.
A chime may even go off when a passenger has pressed their call button meaning that they need the help of a cabin crew member.
This may be because they want food or drink or anything else a flight attendant can help with.
More noises go off when the seatbelt sign goes off which means that the pilot believes the turbulence is rough or is going to get worst and needs the passengers to stay in their seats.
These signals are generally nothing to worry about and are used as a means of communication between cabin crew and the pilot but it is always worth listening out for these chimes and if there is any further instruction by the flight crew.
