The Real Reason You Can’t Use Your Phone on a Plane

While the widespread use of mobile phones on aircraft is generally permitted, it’s crucial to adhere to specific guidelines and regulations. While phones can be used in airplane mode or with cellular connections disabled, some airlines may have additional restrictions during critical phases of flight like takeoff and landing.

Airplane Mode:

Most airlines allow the use of mobile phones in airplane mode, which disables cellular, Wi-Fi, and Bluetooth connections.

Why Airplane Mode?

This is a precautionary measure to prevent potential interference with the aircraft’s sensitive navigation and communication systems.

No Cellular During Flight:

While some airlines may allow Wi-Fi usage during flight, using cellular data or making calls on your phone while airborne is generally prohibited.

Potential Interference:

While modern aircraft are designed to be resistant to electromagnetic interference, there’s still a small risk of interference, especially during takeoff and landing when the plane is closer to the ground and relying on critical systems.

Safety First:

Airlines prioritize passenger safety and may have specific rules regarding electronic device usage during certain phases of flight.

Airline Policies:

It’s always recommended to check with the specific airline’s policy on mobile phone usage before and during the flight.

Airplane mode on flights prevents cell phones from interfering with radar altimeters, which measure the plane’s altitude.

Putting phones on airplane mode during flights is mandatory to prevent interference with aircraft instruments, especially during critical moments like landing and takeoff.

15 Sept 2023 — Research has shown that mobile phones can interfere with the normal operation of aircraft equipment and can also cause interference in pilot’s headsets.

Some airlines may allow cell phones to be used in airplane mode, while others may require passengers to completely turn off their cell phones during the flight.

The Dos and Don’ts of using mobile phones and electronic devices on board aircraft

With smart phones, e-readers, MP3 players and tablets now a standard feature of most airline passengers’ walk-on baggage, it is vital that the aviation industry identifies any potential safety risks posed by these devices and communicates clear advice on how to use them safely to the public. Passengers naturally expect to use their electronic gadgets on a flight in the same way they use them on journeys by train or bus.

However, modern passenger aircraft are heavily reliant on electronic communication and navigation systems which work on the basis of electromagnetic energy transfer and thus they can be susceptible to electromagnetic interference. The degree of risk posed by electronic devices may vary between aircraft types however, making blanket approvals for certain devices difficult.

Following recent research in the United States and Europe aviation regulators have now developed new methodologies for examining the potential risks associated with electronic devices.

Consequently, airlines can now seek approval from national regulators to allow their passengers to use electronic devices in Flight Mode during the entire flight and an increasing amount of airlines have already gained approval.

Regulations

The legislation affecting the use of electronic gadgets on board aircraft, which applies to all European airlines, specifically states that: An operator shall not permit any person to use, and shall take all reasonable measures to ensure that no person does use, on board
an aeroplane a Portable Electronic Device that can adversely affect the performance of the aeroplane’s systems and equipment.

Each EU Member State, however, oversees this rule in relation to its national airlines. The UK Civil Aviation Authority is therefore responsible for ensuring UK airlines comply.

Mobile phones

The use of mobile phones onboard aircraft to make voice calls or send texts is prohibited on UK airlines, unless the aircraft has been especially equipped with an approved mobile phone control system. If the aircraft has indeed been adapted to allow voice calls and/or texting, the aircraft crew will make that clear to passengers including when this is permitted. Passengers should always assume that they cannot make voice calls or send texts on board their aircraft at any stage of their flight, unless informed otherwise.

The primary rule is that phones should be switched off for taxi, take-off, and landing. During the cruise phase of flight most airlines will allow smart phones to be used in ’Flight Mode’ or ’Airplane Mode’ for non voice/text/browsing functions. The aircraft crew should
advise passengers when they can and cannot use mobile phones and other electronic devices.

Whilst the aircraft is taxiing, with the cabin doors closed and engines running, there is still a potential risk of mobile phone signals interfering with some aircraft systems and ground communication between flight crew and air traffic controllers. However, although the general rule remains unchanged – phones should remain switched off until inside the terminal building – some airlines have been able to demonstrate that there is negligible risk of interference on board their aircraft, so on a trial basis, passengers are able to make voice calls and send text messages while the aircraft is taxiing to the terminal. The number of airlines permitting this is still very small, so passengers should assume these ‘taxi-in’ calls are not allowed unless told otherwise by the aircraft crew.

Electronic devices

Airline passengers regularly carry a wide range of gadgets as hand baggage, including laptop computers, tablets/iPads, MP3 players/iPods, e-readers/Kindles and all types of gaming
devices. These devices vary in terms of the strength of the electromagnetic (EM) signals they emit, and they are therefore grouped as those that intentionally transmit a signal and those that do not.

Those that do intentionally transmit, such as laptops and tablets are subject to the same basic rules applied for mobile phones, with most airlines allowing their use in the cruise phase of flight once Flight Mode has been enabled, which turns off all wireless transmitter functions.

However, some airlines operate aircraft that have been adapted to enable wireless communication to transmitting devices. In such cases, the aircraft crew will make that fact clear. Passengers should assume that they cannot use any wireless connectivity of an electronic device unless informed otherwise.

All devices, such as MP3 players and e-readers, emit low levels of electromagnetic energy which have potential to interfere with aircraft systems. However, the results of detailed research led by the Federal Aviation Administration of the United States created a methodology for US airlines to use to demonstrate their aircraft’s tolerance to such electronic devices during all phases of flight.

The European Aviation Safety Agency published similar guidance for European airlines in November 2013 and as a result, a UK airline can now request approval from the CAA for their passengers to be allowed to use electronic devices in Flight Mode for the entire duration of the flight. The airline has to prove they have carried out the required assessment for all aircraft in their fleet before approval is granted.
