Why Skipping Airplane Mode on Flights is a Bad Idea

Ignoring airplane mode on flights won't crash the plane, but it can interfere with cockpit radios and annoy pilots. Learn why compliance is crucial for safety and your phone's performance.

In the age of constant connectivity, the temptation to keep your phone active during a flight is strong. Whether it's sending a last-minute Slack message or staying engaged in a Zoom call, many travelers opt to ignore the airplane mode directive. According to a 2017 Allianz Travel Insurance survey, 40% of Americans admitted to occasionally skipping airplane mode, with 14% sneaking in calls or texts mid-flight. But what are the real implications of this defiance?

While your phone won't cause the plane to crash, it can interfere with cockpit radios by constantly pinging cell towers in search of a connection. This interference creates a buzzing sound in pilots' headsets, which, while not dangerous, is certainly annoying. The Federal Aviation Administration (FAA) bans airborne cell phone use because it can disrupt the radio altimeter, a crucial tool for pilots during takeoff and landing. The issue is more pronounced in the US, where 5G frequencies are close to those used by radio altimeters. However, in the UK and EU, some airlines permit 5G use mid-flight due to different network operations.

Refusing to comply with crew instructions is a federal offense, and while you might not be forcibly removed for forgetting airplane mode, you could face fines or a stern reminder. Beyond legal implications, keeping your phone on airplane mode benefits you personally. It conserves battery life, speeds up charging, and prevents accidental connections to insecure networks. Plus, it helps manage data usage if you're on a limited plan.

Ultimately, ignoring airplane mode doesn't make you a villain, but it does make the flight crew's job unnecessarily difficult. It's akin to not muting yourself on a Zoom call—an inconsiderate move that disrupts others.
