It’s sound.
Airplane passengers were blown away after learning that those ubiquitous “tones” on an airplane are actually a code that crew members use to communicate with each other, among other things. A video detailing this “plane English” currently boasts nearly two million views on TikTok.
“These are [dings] are like a secret language between the cabin crew and the cabin,” content creator Mitch Mohammed explained in the clip.
That’s right, these harmless sounds aren’t just on the seat belt sign and flight attendant call button.
According to the clip, a single noise is heard as the plane prepares to take off or land. Meanwhile, two things mean the plane is at a safe altitude to operate electronics and other provisions, according to the video.
“This is [single ding] usually an indication that takeoff has been approved and sometimes comes with a voice command from the cockpit,” said the ding-guistics expert. “About five minutes after takeoff you will hear two beeps while in the air indicating that the aircraft is in 10,000 feet, which means WiFi and laptops can be used and flight attendants can stand up if it’s safe.”
Meanwhile, a single beep will sound later, indicating that the crew is ready to begin food and beverage service.
There’s also a veritable rundown of other secret things the cockpit uses to communicate with the crew, like mile-high Morse code.
For example, a high-to-low beep means that a flight attendant is signaling another or that the flight deck is trying to reach them.
You never want to hear three beeps as this tonal trifecta signifies an emergency.
The TikTok commentary was amazed by the fly-nese lesson.
“I thought it was the seat belt,” one viewer exclaimed, while another wrote: “Always wondered what it was but also thought it was the call button.”
Meanwhile, other experts confirmed the translation of Muhammad’s aviation.
“As a cabin crew member on EasyJet, I can confirm that the first thing after take-off is a signal from the flight deck to the crew that the equipment is up,” explained one.
