15 Minutes Before Takeoff: Single ding. This is a call from the flight deck (cockpit) to the flight attendants asking them to pick up the phone. (Often this means, please bring us coffee.)
A single chime could be to the flight attendants to advise them of pending choppy air, perhaps serious enough that they should be seated. Another possibility would be, "when you have time, could we please have a coffee?" Two chimes are often used to indicate the aircraft is approaching 10,000 feet in altitude.
Anyone who has taken a flight has also probably noticed the occasional “ding dongs” that go off during your flight. These sounds aren't just arbitrary noises to ignore. They're actually the language used by airlines to communicate with passengers and other flight attendants.
Three low chimes in a row means there is turbulence ahead and all crew should put away any meal carts and fasten their seatbelts.
It's to let the cabin crew know that the landing gear is being retracted. The chimes vary by airline and by type. From the flight deck perspective, the gear is not raised until a positive rate of climb is confirmed, which confirms to the cabin crew that the climb out is proceeding.
/dɪŋ/ A ding is the sound that a bell makes — a kind of metallic, musical ringing.
Bracing in a planned emergency
This allows for the cabin crew to still be able to hear and shout emergency commands whilst protecting the face and head from any flying debris.
In short, SQUAWK refers to the communication that comes from an aircraft's transponder — or the radio equipment that a plane has that allows it to communicate with the radar system of air traffic control on the ground.
Aircraft registration numbers internationally follow the pattern of a country prefix, followed by a unique identifier made up of letters and numbers. For example, an aircraft registered as N978CP conducting a general aviation flight would use the call sign November-niner-seven-eight-Charlie-Papa.
If there are not enough passengers who are willing to give up their seats voluntarily, an airline may deny you a seat on an aircraft based on criteria that it establishes, such as the passenger's check-in time, the fare paid by the passenger, or the passenger's frequent flyer status.
Squawking 7700 will allow ATC to prepare for a quick landing, allowing controllers to inform nearby aircraft and clear any runways needed, as well as inform the authorities of any other support necessary (such as fire services or an ambulance). Having such a code available is very useful.
What is turbulence? The meaning of turbulence is a sudden, violent shift in airflow. It creates up and down currents caused by irregular atmospheric motion. You can also define turbulence as that sudden jerking you sometimes feel in an airplane!
Typically, one short beep means that it passed the test successfully or a series of beeps means that something is wrong with the computer hardware. The location of the hardware fault is given by the pattern of the beeps. It may also be called the POST code.
One long, continuous beep generally means that there is a hardware problem – often memory related – that can prevent your computer from starting up at all. If you can't start your computer properly, you'll need to take a look at the physical hardware inside your machine.
The popularity of using call signs only increased during the Vietnam War, and by the 1980s, it became an institution. Today, getting a call sign is a rite of passage. Pilots and naval aviators do not get to pick their own call signs.
Pilots and other aviators do not get to pick their own call signs, Harmer said. Instead, they are assigned their official nicknames when they join their first deployable squadron. These call signs are usually based on someone's personality or foibles and they tend to stick with aviators for their entire careers.
The call sign tradition is celebrated by aviation communities across all military branches. These pilot nicknames can quickly identify an aircraft or individual, and they also help to confuse the enemy, who might be listening in on your communications.
Under normal circumstance even interception missions are supposed to work with ATC. Squawking 7777 is sort of a last resort thing for the DoD to tell ATC to get out of their way and get everything else out of their way.
0000 — A generic code that is not assigned and should not be used. 1200 — VFR aircraft. The default code for all flights–if you aren't asked to set anything else, you should set 1200. 7500 — Hijacking. 7600 — Voice radio failure.
Wake turbulence poses a major risk to other aircraft, so pilots and ATC use the term “heavy” in radio transmissions as a reminder that the aircraft's wake may be dangerous to others passing behind or below the flightpath of these larger-mass aircraft.
Not Being Courteous
“Having “savoir vivre,” a “please” and “thank you” would never go wrong. As a general rule, to be treated nicely, one needs to behave nicely,” said a flight attendant. Keeping headphones in and not taking them out when attendants are trying to communicate with you was also a big no-no.
The use of high heels in flight attendant uniforms dates back to the early days of air travel, and was originally a holdover from the dress codes of registered nurses who were the first air stewards. It was believed that high heels would make female flight attendants look smart and presentable.
Sometimes flight attendants will wake passengers up so they can eat. According to a post on Travel.stockexchange.com, sometimes flight attendants will ask the other person that they're flying with if they should leave the meal there. That's definitely helpful.
