Why passengers must turn off devices during flight remains a critical safety issue in modern air travel. Yet, many still ignore these warnings. Often, when cabin crew ask travellers to shut down electronic devices—especially phones—during takeoff and landing, it’s met with confusion, resistance, or outright defiance.
After safety demonstrations, the next instruction is often clear: switch off all electronic devices completely, not just to flight mode. Yet, this directive is often questioned. However, there are good reasons behind it. And they relate closely to one key aviation concern—interference.
Aviation authorities stress the importance of clear communication between pilots and the control tower, especially during takeoff and landing. These two stages are the most critical phases of flight. If electronic signals from mobile devices interfere—even slightly—with cockpit communication systems, the result can be disastrous.
Imagine a radio program. If you’re calling in live, you are usually told to move away from the radio or switch it off to reduce feedback. Now, apply the same principle to a flying aircraft. Think about it—an aircraft cruising at 30,000 feet has no parking space. Any interference must be avoided at all costs.
A pilot once noted the importance of eliminating all distractions in flight, especially anything that could impair technical systems. Although not directly referencing electronics, the principle of safety-first governance applies.
During one of my flights to Abuja, I witnessed a confrontation. A male passenger refused to switch off his phone even after being asked multiple times. He became aggressive towards a female flight attendant. It took intervention from the First Officer to ensure compliance. He nearly got deplaned before reluctantly obeying.
This scenario is all too common. Many passengers simply do not understand that defying flight crew orders about electronics could lead to being removed, arrested, or even prosecuted. Safety rules are not suggestions—they’re law.
And this issue is not just a Nigerian problem. A U.S. aviation survey revealed that four out of ten passengers admitted they didn’t switch off devices during flights. This alarming trend shows how global the disobedience is.
There is some evidence, though rare, of electronic interference with onboard systems. An International Air Transport Association (IATA) report documented 75 incidents between 2003 and 2009 where pilots suspected interference from passenger devices.
Still, people argue that no crash has been directly caused by mobile phones. That may be true. However, aviation is built on preventing problems, not reacting to them. So, even the possibility of disruption is taken seriously. Precaution is always better than regret.
The rule generally is this: below 10,000 feet (3,000 meters), all portable electronic devices must be turned off. Flight mode is not enough in some regulations. Above that altitude, the crew will often give clearance to use certain items like laptops or music players.
Personally, I’ve filed stories mid-air, transcribed interviews, and used voice recorders—but only when the aircraft was at a safe cruising altitude and the crew allowed it. The rule is clear: obey all crew instructions. It’s for your safety and the safety of others onboard.
So, when the crew says turn off devices during flight, especially during takeoff and landing, please comply. It’s a small sacrifice to ensure smooth communication, avoid potential interference, and safeguard every life aboard.
Next time you board, listen carefully, follow safety protocols, and help ensure safe skies for all.
