Pilot explains what really happens if you don’t put your phone on airplane mode while flying

A commercial pilot has used TikTok to address a common misconception about an often-overlooked flight safety rule: switching your phone to airplane mode.

In a video posted by TikTok user @PerchPoint, the pilot delivered a “friendly PSA” to explain why enabling airplane mode is not a “conspiracy theory” but a small yet important step that supports safety during flights.

“Putting your phone on airplane mode won’t stop the plane from flying,” he said, “but it does help prevent annoying interference in the cockpit.”

He clarified that forgetting to switch a device won’t cause a crash. However, when multiple phones attempt to connect to cell towers during flight—especially when receiving calls or texts—the resulting radio waves can interfere with pilots’ headsets.

“I once heard this loud buzzing in my headset — like a mosquito or wasp flying around my ear — while trying to land the plane,” he explained. “It made it hard to hear critical instructions from air traffic control.”

Such interference, while not catastrophic, can be distracting—particularly during crucial phases like take-off and landing, when pilots rely on clear communication and often operate with limited visibility.

Travel and Leisure notes that most aviation accidents happen during these stages, underscoring the importance of uninterrupted communication with ground control.

While leaving airplane mode off won’t bring down a plane, it can create disturbances that affect the crew’s focus.

In short, enabling airplane mode isn’t optional—it’s a small courtesy that helps maintain safety and focus for everyone on board.
