### Why airlines don't allow cell phones

The Federal Aviation Administration (FAA) just announced that most electronic devices can now be used on airplanes, all the way from takeoff to landing. But you still can't make a call on your cell phone during a flight, and all devices must be set to "flight mode." Why can't you make calls on flights? To get a better understanding, let's use some trigonometry.

Airplanes communicate and navigate using a band of radio waves called the airband, which uses frequencies between 108 and 137 MHz (or megahertz). Radio waves are electromagnetic waves, or waves of light, which travel through space like the sine function. Waves with higher frequencies move up and down, or "oscillate," faster, while lower-frequency waves oscillate more slowly. Here are examples of waves that have different frequencies:

How do the frequencies of cell phones compare to those of the airband? Well, it depends on the carrier (Verizon, AT&T, etc.), but for the most part they're between 500 and 2500 MHz. So cell phones send and receive radio waves that are close to the Airband, but are slightly higher in frequency.

If you were to make a call on a plane, then the cell phone's radio waves and the airplane's radio waves would add together. The airplane's waves are probably a lot stronger than the waves coming out of your phone. So what happens if we add a very weak cell phone signal (say, at 700 MHz) to a strong airplane signal at 120 MHz?

The sum of the two waves looks pretty close to the airplane's signal. But what happens if the cell phone signal were a lot stronger?

Suddenly, the sum looks quite different from the airplane's signal, and that's what worries the FAA. While there are mathematical tools that tease apart signals with different frequencies that have been added together, pilots and officials are concerned that cell phone radio waves could still interfere with the communication and navigation of airplanes.

If cell phones instead used frequencies that were really far away from the airband, then the risk of interference would be even smaller (even if the phones emitted really strong signals). Why do you think that is?

1. This is a very serious matter you rise here, When ever i travel to airplane, I also don't take my laptop with me and due to this pay to do an assignment, This is only for safety.

2. This is a really significant issue that you raise. I always bring my phone when I fly, and I do it mainly out of concern for my safety.

I just bought the dissertation proposal help from an online site and I randomly clicked open this page that proved to be quite informative.

6. For the Federal Aviation Administration, safety is the highest concern. Portable electronic devices, including cell phones, iphones in karachi pakistan, emit radio signals that officials worry will interfere with aircraft communications or flight control, navigational and other on-board electronic equipment.

7. I'm not sure why airlines don't allow cell phones, but I imagine it has to do with preventing people from making calls during takeoff and landing. Maybe they're also concerned about people using their phones to take pictures or record videos during flights.

8. I assume it has to do with keeping passengers from making calls during takeoff and landing. Airlines don't allow cell phones. They might be worried about passengers using their phones to capture pictures or film videos while flying as well. While looking for someone to do my assignment for me cheap in the UK, I came across your website, which I think to be rather intriguing. Keep up the great job on your website, please. I'll return to read more of this informative content.

9. Airlines do not allow cell phones on flights for a number of reasons. The main reason is that cell phones can interfere with the airplane's navigation and communication systems. This can cause major safety hazards for the passengers and crew on board. Additionally, cell phones can be a distraction for pilots, which can also lead to safety concerns.

10. I think it's great that there are so many best app development companies out there that can help create innovative solutions for businesses. However, I think it's important to consider why airlines don't allow cell phones. This is for the safety of the passengers and crew, as the phones can interfere with the aircraft's navigation systems and communications. It's important to remember that the safety of everyone onboard should always be a priority.

11. This article provides valuable insights and useful information for anyone curious about why airlines don't allow cell phones, and I would highly recommend it to others.

12. Due to some radiation issue, mobile phones are not allowed in airlines. However, when the plane take off then you can use your cell phones. I know much about the radiation issue because I am providing Electrical Lighting Installation services in the USA and sometimes, I also face some radiation issue in electric work.

13. I think due to some radiation purpose, it is not allowed in airlines. I have experienced this when I visited Vancouver for Video Production Vancouver services. So, air crew asked me to switched off my cell phone.

14. Hi there, interesting topic! While it's understandable that cell phones might be disruptive on flights, it's also important to consider the potential risks of electromagnetic interference. In the meantime, it's always a good idea to take care of yourself and indulge in some self-grooming treatment to pass the time.

21. OH, okay! I always used to wonder why people are told to switch their phones to airplane mode when the flight is about to take off and finally this query of mine has also been resolved.

22. Airlines don't allow cell phones for reviews due to potential interference with aircraft communication systems. Safety regulations prioritize avoiding any electronic interference during flight. Passengers can use their cell phones in airplane mode for non-transmitting activities, such as reading, gaming, or taking photos. Reviewing an airline experience is encouraged once the aircraft is safely on the ground. Compliance with these rules ensures a secure and uninterrupted flight experience for everyone.

23. Cell phone use is restricted aboard airplanes primarily to prevent potential disruption of vital onboard equipment. Limiting cell phone use helps to improve overall safety by reducing any interference that could jeopardize communication and navigation systems crucial for flight operations, similar to how the N2K-PAC-200W - Cisco 200-Watt Hot Swap Power Supply for N2000 Series is meticulously regulated to ensure smooth operations.

25. The primary reason why airlines prohibit cell phone usage during flights is because of the possibility of interference with aircraft communication systems. Even though contemporary aircraft are built to resist electromagnetic interference, taking this precaution guarantees safety in all circumstances. Cell phone electromagnetic signals have the ability to interfere with communication, navigation, and avionics systems. Airlines enforce rules requiring passengers to turn off or put their devices in airplane mode during critical flight phases in order to reduce potential risks. The overall safety of passengers and the integrity of flight operations depend on compliance with these guidelines, even as technological advancements continue to improve aviation safety.
