More people are afraid of flying in planes that we know of. Although technology has managed to come up with an astounding innovation, the idea of flying in a tin can doesn’t sound appealing to most. Some of the passengers seem to be on edge, while their mind is all racing thinking of several things including the different types of alarm sounds made in the cabin during flight hours. Here is your guide to help you decode the meaning behind those alarms. And whether you should be alarmed or not, you will find out if you continue reading.
1-20 minutes before taking off:
When you hear two dings one after the other with the first one being of higher tone, while the other of lower tone. This is basically the call made from the intercom, which indicates that one of the crew members is wishing to speak to another member of the crew.
2-15 minutes prior to taking off:
The sound heard just 15 minutes of taking off is likely a single ding, which is a call made from the cockpit or the flight deck to the attendants of the flight asking them to receive the phone call. More often than not, this call is to ask the attendants to get coffee to the pilots (says an insider).
3-10 minutes to take off:
You are likely to hear a light pounding sound from under the flight continued by two whirring sounds more like the noise of a drilling machine. This suggests that the staff is shutting the cargo holding door now.
4-When the plane starts to taxi the runway:
When the flight just starts to take the runway, you will hear the sound of gushing wind. This basically indicates that there is a change in the source of air. The experts tell that air is used in starting the engine of the flight and is also used to cool the cabin, which is further redirected. The noise of the wind suggests that redirection of the air is being carried out.
5-Creaking and Rattling sound:
When the flight is beginning to fly, you will encounter a lot of rattling and creaking noises from various components of the plane. You must understand that that is perfectly normal. The galley components and interior panels on the aeroplane are provided with a little room to move around so that they can be changed out quickly. That results in the routine creaking and rattling in the insides of the flight when it’s taking off.
When the flight is about to take off, you are bound to hear loud thumps from under the plane, which is further followed by repeated whooshing noise of a spinning propeller. These sounds are generated from the engines of the flight when the engine is adjusting with the temperature and airflow when the plane is climbing to heights.
7-5 minutes just after takeoff:
When the flight has taken off, you are going to hear two loud beeping sounds; this is basically to indicate that the plane has now reached 10,000 feet. Through these sounds, the cabin crew is kept informed.
