Flying on a Boeing 787 Dreamliner is a different sort of experience: Not only is the aircraft more fuel-efficient than most on the market, it also has a bulb-less cabin, swaps out window shades for "smart glass" that passengers can adjust to five levels of sunlight and visibility, and has cabin pressure at an equivalent of 6,000 feet instead of the 8,000 feet. (All of this, suffice to say, helps fend off that pesky jet lag.) The relatively new Boeing aircraft also has five times the electrical power of conventional airlines, and unsurprisingly, has a leg up on typical flight systems—but it also has a major drawback.

In a document published last Friday, the Federal Aviation Administration noted an "unsafe condition" that required immediate attention. It now requires airline operators to shut off and then restart the electrical power on their 787 Dreamliners within seven days of the announcement, and then in "intervals not to exceed 21 days." The reason? Pilots could potentially lose control of the airplane—three flight control modules can simultaneously reset if they're left on for 22 days. Not great if you're at 30,000 feet.

While industry experts note that it is extremely rare for operators to even leave a Dreamliner on for more than a week, carriers who fly the 787 Dreamliner around the world are expected to follow protocol until a permanent fix by Boeing has been delivered in early 2017. (There are 489 Dreamliners worldwide, 99 in the U.S., and this glitch is apparently present in all of them.) Flying a Dreamliner sometime soon? Just ask the pilot to reboot.
