Why Are You Required To Turn Off Your Electronics On Airplanes?

Studies suggest that the use of electronic devices on airplanes could disrupt the systems of an aircraft.

Ever thought about how important it is to turn off your electronic devices while traveling on a plane? The answer is simple: They emit energy.

It’s widely believed that flight attendants and the Transportation Security Administration (TSA) agents tell passengers to turn off their devices before they board a plane.

Aside from being required to turn them off, this is also for the safety of everyone on the plane. Since electronic devices can affect the atmosphere, they should also be turned off to prevent interference with the cockpit.

The systems of a plane are designed to work seamlessly and provide the most accurate information possible to guide the aircraft. If your devices are used while in flight, they could interrupt the readings and cause the system to make an incorrect adjustment.

How Your Electronic Device Affects The Plane’s Instruments And Other Passengers During A Flight

Smartphones, tablets, and other electronic devices have become ubiquitous in the 21st-century. They can be used to play games, communicate with family members, and browse the Internet.

Before a flight, passengers are reminded to turn off their devices and keep them in airplane mode. Doing so can prevent cellular service from interfering with the navigation equipment of the aircraft.

Before boarding a plane, passengers should first understand how their electronic devices interact with the aircraft. In order to establish a wireless connection to a cellular tower, an electronic device needs to become a low-power radio wave transmitter.

Although an electronic device can still function in cellular mode, it cannot transmit a radio signal during airplane mode. This means that its signals could potentially interfere with the various systems that control an aircraft, such as its navigation equipment and collision-avoidance equipment.

Modern airplanes use electronic equipment that are designed to shield them from radio waves. Although some devices can cause interference, it’s unlikely that they will cause an accident.

Unfortunately, the signals from these devices can still be heard in the headphones of pilots and navigators, which makes them hard to read. They also make it impossible to read the messages sent by airmen.

Due to the annoyance of pilots, many airlines ask their passengers to keep their electronic devices away from the cockpit. In 2014, safety regulators of various countries, including the USFAA and China’s Civil Aviation Administration, decided to keep the restrictions in place.

In China, it’s against the law to use electronic devices during a flight. Doing so could result in a fine of thousands of dollars or even a jail sentence.

Despite the availability of cheaper airphone services, many international travelers still prefer to use their smartphones to make calls from the air. To avoid getting lost in the middle of a flight, cellular towers are installed on each aircraft.

In-flight cellular service is provided by picocells, which are small wireless devices that keep cellular signals at a minimum. Many European airlines use this technology to provide in-flight calls. However, American carriers are still waiting for the FCC’s approval.

Radio Waves Are Emitted By Electronic Devices

In most cases, the aviation norms in place for the use of electronic devices are the same in every region.

On the other hand, electronic devices such as smartphones and laptops can stay connected to the world below you through radio waves. Despite this, aviation regulations still state that you are not allowed to use your phone in plane mode.

Due to electromagnetic interference, this restriction applies to devices that are equipped with radio transmitters. According to experts, these components can affect the safety and navigation of an aircraft.

Although this restriction is not restricted to Kindles, the devices themselves can still cause interference to the radio waves emitted by airplanes. These radio waves could affect the systems used by the aircraft, such as collision avoidance.

If the devices are damaged, their reception can be affected by the additional signals from other devices.

What Effects Do Radio Waves Have on Airplane Communications?

On a normal day, your phone can find a wireless tower wherever it is placed. It can then connect to the one closest to its location and allow you to make calls and send emails.

However, when flying in an airplane, the speed of the aircraft and the distance from the network towers can dramatically change. During this time, your phone and the network towers can get confused. This could affect the communications of an airplane.

Here’s Why Airlines Need You To Use ‘Airplane Mode’ On Your Phone

Most people think that having a phone in Airplane Mode prevents it from interfering with the navigation equipment on a plane. However, this is not the real reason why it’s required on flights.

Active cell phones, according to pilots, could interfere with their navigation systems.

The Federal Communications Commission prohibits the use of cell phones on airplanes to prevent radio interference. This means that devices that are active at that altitude could cause service disruptions on the ground.

Some international airlines allow their passengers to make phone calls and send text messages in the air. However, most of them restrict this feature to prevent interference.

  • “Inflight Wi-Fi does not support cell phones or Voice-over-Internet Protocol (VOIP) services.” – The airline American Airlines
  • “VoIP and Video Chat are also prohibited for the safety and comfort of our guests.” Virgin America’s remark
  • Neither voice nor video calls are permitted.

What Happens If You Don’t Put Your Phone on Airplane Mode While Flying?

Most people do not follow the order to disconnect their phones when an aircraft lands. Others have mistakenly turned off their devices thinking that they’re in airplane mode.

How Does A Cell Phone Affect Plane Navigation?

It’s a common belief that a cell phone might cause interference in the navigation systems of an aircraft. But, in most cases, these systems are designed to prevent outside interference.

The NTSB has never issued a safety recommendation regarding the use of portable electronic devices on airplanes. There have been no documented cases of electromagnetic interference causing a crash.

No one wants to send a signal that could interfere with various safety features of vehicles. Although there is no scientific evidence supporting the idea that radio waves can cause equipment failure, it is still possible that they could. Many people still rely on their cell phones while flying.

Is The Plane Going To Crash?

Although a phone won’t cause a plane to crash, it can still be annoying to the air traffic controllers and pilots. To effectively use it, you need to increase the phone’s power. Doing so will allow the device to communicate effectively.

Although the FCC prohibits the use of mobile phones in flight, the FAA does not regulate the use of electronic devices on aircraft. This means that airlines can decide if they should allow the use of certain portable electronic devices on an aircraft.

In Europe, due to the introduction of regulations, many airlines have started allowing the use of mobile phones in flight. However, some still do not allow the use of these devices during take-off and landing.

Many passengers are urging governments and airlines to allow the use of mobile phones in flight. On the other hand, safety agencies and safety boards are still against relaxing the current regulations. There are various factors that affect the safety of airplanes, such as technological and social issues.

Noise That Is Unpleasant

This increase in power can make the radio emissions that the controllers and pilots can hear very unpleasant. Also, it can distract the pilots by sending out signals that are very similar to those coming from the cell phone.

The distance between an airplane and its passengers is a factor that influences how noise levels are computed. This is why we use noise abatement procedures to keep airplanes as high as possible.

The weather can affect the sound waves produced by an airplane. This phenomenon makes aircraft noises seem louder than they actually are. It’s also due to the physics involved in how these sounds travel to our ears.

The thickness of clouds can also affect the sound waves produced by an airplane. For instance, if the cloud is thick enough, the noise produced by an aircraft will bounce off the ground.

Trees absorb sound better than other objects. For instance, if a car is driving on a road and the sound waves from it are reflected in the surrounding vegetation, it doesn’t seem as powerful.

Also, when flying over water, the sound waves from an aircraft will bounce off the surface, which effectively amplifies it.


Some airlines have in-flight cellular service. It works by sending and receiving calls from and to a cell station located on the plane. In most cases, this feature works seamlessly.

Although a cell phone call may not cause an accident, it’s still important that you turn off all of your devices while flying. Your pilots will thank you for doing this.

After settling into our seats in an airplane, you’ll invariably hear the announcement that says “Please turn off your electronic devices” as the plane is about to take off.

Although the Federal Communications Commission prohibits the use of mobile phones on an airplane, the FAA does not actually enforce this ban. In fact, it has allowed the use of electronic devices on aircraft in the past.

In 2008, Air France allowed its passengers to use their cell phones to make calls and send emails. Due to the increasing demand for connectivity, airlines are developing new technologies that will allow them to safely accommodate the use of electronic devices on board. It’s a good idea to keep your devices in your pockets since it will allow you to enjoy the flight experience without being distracted.
