And often in terminal areas, within 50 miles of an airport, we change runways and when we do that we often program the changes into the system. I might reprogram the FMS once or twice per flight. If you were going to your aunt's house and then decided to go to your sister's house instead, you would reprogram your GPS. Certainly, if there were some sort of diversion deemed necessary by the crew, they would reprogram the FMS. It could be weather-related, or it could be an air traffic control directive. Why might a pilot program a change into the FMS mid-flight? Quite often, the airline policy for newer generation aircraft, like Airbus and probably the 777, is to turn on the autopilot shortly after takeoff, usually at particular altitude. There are methods of hand flying the airplane that will keep it on that same course programmed into the FMS, and some pilots like to hand-fly to keep their skills up. They use it for navigation almost immediately after takeoff, but the decision to fly manually versus on autopilot is up to the pilot. If a GPA was undisturbed, over time he or she might be able to figure that out. General Aviation (GA) GPS systems are quite similar to the FMS as well, so a GA pilot could input some information into it, but I'm not sure that a GA pilot would know what information to input.

An aircraft mechanic might have some idea of how to use it but, at the very least, it would take someone with a pilot's knowledge of the system itself. Who could operate the FMS in a Boeing 777?Īnyone trained on the system, so probably a commercial pilot. There are a couple of different manufactures of the system, but if you really break them down they all operate pretty closely to each other.

Battery life saved this way may vary by phone, but using Airplane Mode on a plane may last a bit longer after landing.Play icon The triangle icon that indicates to play Is the FMS basically the same in all large airplanes? In case you didn’t know, wireless signals drain a phone’s battery faster, so airplane mode helps extend battery life. He said that if the radio altimeter’s functions are affected, that is, it cannot tell precisely how far the aircraft is from the runway, the results can be disastrous. But unfortunately, it can be dangerous if something goes wrong, so avoid doing it.Īccording to pilots, radio altimeters are used to determine the correct altitude of an aircraft during flight, especially in areas where visibility is reduced due to fog, snow, or bad weather. If you forget to switch your phone to airplane mode during a flight or do it on purpose, the chances of major damage are negligible.

That is why pilots tell people to switch to airplane mode, especially before the plane takes off and lands, so there are no problems. These signals can affect aircraft transmissions, especially if there is an emergency where the pilot needs a simple line of communication to communicate with air traffic control, but telephone signals can affect that communication. And as mentioned above, mobile phones and tablets use similar signals. Aircraft communication and navigation systems use radio frequencies emitted from the surface and are more likely to interfere with radio signals. The reason for this is not simple but simply put, airplane mode does not allow any potential interference with sensitive aircraft systems.

So what is the purpose of this directive, and why are airlines doing it? What is airplane mode?Īirplane or flight mode temporarily suspends smartphone signals and Wi-Fi signals, but other functions continue to work. If you’re traveling by plane, you’ll often hear flight attendants tell you to switch your phone to airplane mode. But what is its purpose, and if we do not use this mode on aircraft, can there be any significant damage? What can happen if we do not use airplane mode while traveling on a plane? Do you know its purpose? Many people use smartphones now and have seen airplane or flight mode.
