But what purpose do they serve? As it turns out, the dim lighting is a precautionary measure that allows passengers’ eyes to adjust more quickly during an emergency evacuation. As Chris Cooke, a pilot with a major domestic carrier, puts it: “Imagine being in an unfamiliar bright room filled with obstacles when someone turns off the lights and asks you to exit quickly.” The raised window shades bring natural light into the cabin, just in case it’s needed. _Melanie Lieberman is the Assistant Digital Editor at_ Travel + Leisure. _Follow her on Twitter and Instagram at_ [_@melanietaryn_](https://instagram.com/melanietaryn/). _This_ [_article_](http://www.travelandleisure.com/blogs/why-do-airplanes-dim-lights-on-takeoff) _originally appeared on_ [_TravelandLeisure.com_](http://www.travelandleisure.com) ## Transcript [ MUSIC ] Airplanes used to be one of the only places we had a legitimate excuse to stay disconnected for a few hours. A five hour flight meant we had time to nap, read a book, or contemplate the meaning of life while hurling 5, 000 miles an hour through a metal tube. But these days, about two thirds of every flight over the US, has onboard internet. Internet but how does it work? The airborne WiFi system you've probably used before basically works like a cell tower in reverse instead of pointing downwards at smartphone users the towers point upwards at a plane the planes got a receiver and a transmitter on the belly of the aircraft that gets that signal and then distributes it through the cabin like a regular WiFi hotspot. But this approach can be painfully slow. Its low bandwidth to start and then all that bandwidth is cut up between every passenger who wants to connect. Don't count on streaming Netflix with this sort of system. So what's the solution? Several companies are moving towards systems that combine ground based cell towers with internet satellites. That's a much higher bandwidth setup but you'll still be sharing it with a bunch of different passengers so it won't be super fast. What's the hold up on faster internet on planes two reasons first there's government regulations that need to be cleared But the second one and the bigger one is cost. Installing this new system means airlines have to put expensive new gear on their aircraft, and some just haven't been willing to do that yet. Still there's obviously customer demand for faster on- board Wi- Fi. WiFi, so expect to be streaming Netflix within the next few years. For now enjoy that disconnected bliss while you still can.
