Flight attendants have a lot of responsibility in looking after passengers and attending to any of their needs. They also need to communicate with one another while in-flight and may not want any other passengers to know what they are talking about.
Noises and chimes can be heard during take off and landing as well as throughout the flight.
In a blog post, Qantas revealed the real meaning behind the chimes and what they mean.
The first chime you hear once taken off is a sign sent by the pilot to the crew to indicate that the landing gear has been retracted.
This chime also means that the most dangerous part of flying is over.

The first and last 10,000 feet of flying are generally considered to be the most dangerous parts of flying.
This means you will often hear another chime when the pilots are preparing to land.
While this varies between airlines, it also means that flight attendants can start to prepare for their drinks service too.
A single chime means that a passenger needs assistance from the crew and this is either sent by the passenger themselves or flight attendants.

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.
When a flier needs more food or drink, a crew member can call another crew section which and that is when a high-low chime can be heard.
Many people get scared when they hear the noises onboard and although there is no reason to be scared of them, passengers should understand what most of them mean.
When the plane is about to experience a rough turbulent patch, a trio of low tone chimes indicate that the flight staff need to get back to their seats.
However communication between the crew becomes more secretive or serious if anyone is seen trying to enter the cockpit while flying.
One 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.”
This means passengers do not tend to know when the crew are communicating secretly with the pilot however there are many secret codewords the staff sometimes use discreetly.
One word that indicates a security issue is ‘Code Bravo’.
This is the code for a general security alert at an airport or onboard the plane.
Security officials will typically say the word very loud and it often means that you must freeze.
This makes it easier to pinpoint the source of threat or someone who is causing trouble.
