Every time you're about to take off on a plane, you hear the warning: "Your portable electronic devices must be set to airplane mode until further notice." You already know what to do with your smartphone: there's a simple airplane mode toggle on both Android and iOS. But what about your MacBook? A MacBook is an electronic device, and it's certainly portable, so you might be puzzled about using it while in flight.

What Does Airplane Mode Do
First, let's clarify what airplane mode does and why it exists. On an iPhone, for instance, airplane mode setting disables the following services: Cellular: This stops your phone from communicating with the cell towers on the ground. Wi-Fi: Disconnects your device from all Wi-Fi networks and prevents it from searching for networks.

GPS: Stops your device from getting signals from the satellite. The reason airplane mode was originally introduced is that all these services transmit and/or receive radio signals at multiple different frequencies. The signals can potentially interfere with the radio system of aircraft as well as the towers on the ground.

So far, there's been no evidence that radio signals emitted by electronic devices pose a more serious threat than a pesky noise on the aircraft radio. In theory, though, even that noise could distract the pilot or prevent them from getting critical information. The has record of a few incidents where passengers' devices allegedly caused radio static interference and even compass system malfunctions.

But with your MacBook, it gets trickier. Because airplane mode for smartphones disables Wi-Fi, Bluetooth, and GPS---which, aside from GPS, are also available on a MacBook---you'd assume they pose a risk, too. However, the main culprit of any possible interference is the GSM/3G radio.

Its signal is way more powerful than those emitted by the Wi-Fi and Bluetooth radios and received by the GPS. And MacBooks simply don't have that. The airplane mode setting on iOS and Android disables all radios present in your device because it's easier and safer than picking and choosing.

So from a legal standpoint, there seems to be no need to put your MacBook in airplane mode. However, switching off Bluetooth and Wi-Fi can help you save battery power, which is vital when you need your laptop to last for the whole flight. MacBooks don't have an actual GPS chip like your phone does.

Instead, location services uses nearby Wi-Fi networks to figure out your location. This affects battery charge only when an app is actively using it. If you have an app constantly trying to pin down your location---like a weather tool that runs in the menu bar---you can either shut down the app or disable location services.
