Everyone who has been on holiday via a plane will have been told that it is of paramount importance you turn your phone off or onto flight mode.
The popularly accepted myth is that the mobile signals can disrupt the aircraft’s operating system and potentially cause a catastrophic accident.
Well, as reported by the i100, that may be a massive exaggeration of the consequences.
A pilot revealed on Quora what happens in roughly three per cent of cases:
You may have heard that unpleasant noise from an audio system, that occasionally happens when a mobile phone is nearby.
I actually hear such noise on the radio while flying. It is not safety critical, but is annoying for sure.
Someone else added:
It makes a bzzzt-bzzzt-bzzzt-bzzt-bzzt.
Now imagine that noise in the pilot’s headphones, while [he or she] is receiving a critical bit of information from ground control!
Integral to safety, maybe not? But in the interest of not distracting the pilot it is still definitely advised.
