An Ibom Air flight became a national talking point after passenger Comfort Emmanson clashed with crew over phone use, insisting her device was in flight mode.

The situation escalated, she was arrested, and a lifetime ban was announced. By August 13, Aviation Minister Festus Keyamo said the government had asked police to withdraw the case, and airlines agreed to lift the ban.

What Airplane mode does (and doesn’t do)

Airplane, or flight mode, switches off a phone’s cellular radio, the part that connects to ground towers. That single change is important because many jurisdictions still prohibit airborne cellular calls to protect both aircraft systems and ground networks. 

Most airlines now allow Wi-Fi and Bluetooth once the aircraft has been shown to tolerate portable electronic devices, but they still require cellular functions to remain off while airborne. 

In Europe, regulators even permit managed 5G service on some aircraft via onboard “picocells” that keep phones at very low power and route traffic through the plane’s system. That’s a policy choice with safeguards; it is not permission to ignore crew instructions.

Can devices really interfere with an aircraft?

Modern airliners are rigorously shielded and tested, and many fleets are certified for gate-to-gate use of personal electronics. Even so, aviation safety treats interference as a risk to be managed rather than dismissed. 

Operators assess electromagnetic risks and keep procedures in place that allow crews to isolate and switch off a device if it’s suspected of causing an issue. 

Historical reporting shows only a small number of suspected interference events across hundreds of thousands of flights, and no commercial accident has been conclusively linked to passenger phone use. 

In practice, that means the probability of a problem is low, but crews still retain the authority to manage it quickly and decisively.

Nigeria’s rulebook and the captain’s authority

Nigeria’s Civil Aviation Regulations state that no one may use a personal electronic device that could adversely affect aircraft systems unless the operator has determined it’s acceptable, and the pilot-in-command has informed passengers of permitted use. 

In simple terms, the airline’s policy and the captain’s direction decide what’s allowed on that specific flight. “It’s on airplane mode” is not the final word if the crew instructs otherwise.

Why airplane mode still matters in the 5G era

Airplane mode preserves a safety margin by silencing the cellular transmitter during critical phases like takeoff and landing. 

It also protects ground networks, because an unmanaged phone at cruising altitude can try to connect to multiple towers at once.

Just as importantly, it helps cabin operations: during safety briefings, taxi, takeoff, and landing, crews need passengers focused and able to comply instantly with instructions.

Airplane mode, and, when required, powering devices fully off, keeps that environment orderly.
