When you enter an aircraft they’ll be a hum of background noise because the air conditioning and electricity are running.
When the engines start the lights may flicker and these humming sounds may stop and start. This is because they switch from being run by an auxiliary ground unit to being run from the aircraft. As each one switches over it can cause them to switch on and off momentarily.
You’ll also hear other electrical equipment being switched on. Some large jets take a while to start as each system is switched on in turn. Its just like when you start your computer and wait for everything to load.
Whilst travelling to the runway you may hear the rumble as the front wheel goes over the runway lights.
Noises on the ground
Noises in flight
Many anxious flyers don’t like the sound of take off, they think the aircraft is operating at its limit. I can reassure you it’s not, despite the noise it’s operating well within its maximum capabilities. During take off the pilot actually keeps the plane on the ground a little longer to build in a safety buffer.
During the flight you may hear wind noises as the airflow changes when the aircraft speed changes and even changes in engine noise as the aircraft power settings are changed.
When landing the thrust reversers will add to the noise, these allow the aircraft to slow down really quickly. They make noise when they are deployed and move into place.
Remember that noises can appear louder when flying at night or sitting away from windows. This is because your mind is compensating for a lack of visual evidence so it tunes in to what you hear to try to build a better picture. Equally if you’re in a heightened stress response they’ll also appear louder as your body tunes into minute details in the hope of helping you overcome the ‘danger’.
All of these noises are perfectly normal and not dangerous in any way. Knowing more about what you’ll hear and expecting it will go some way to reducing your bodies natural stress response. Remember that all these noises are a sign that everything is working as it should and remind yourself that you are safe.
I hope that helps, until next time.
