So any out-of-bounds situation is also perfectly trackable. The data the aircraft transmits also includes the so-called ‘squawk’, or the responder code, which, at times, might serve to pass over coded information (in case of emergency the value is set to 7700, in case of hijacking to 7500). In this mode, an aircraft regularly (approximately once a second) transmits the GPS location data (latitude, longitude, altitude) as well as speed (including vertical speed), of the aircraft’s unique ‘address’ and flight number via the 1090 MHz channel. But our interest now lies within one of the other functions: ADS-B Mode-S. Also, not only dispatchers, but pilots as well are able to see the whole traffic.ĪDS-B is a relatively complex and sophisticated system which enables the pilots to get the most recent weather and terrain updates, or other information. Initially, this broadcast technology was designed for dispatchers to locate aircrafts with greater precision than possible with legacy micro-wave radars.

This is possible thanks to Automatic dependent surveillance-broadcast technology, or ADS-B, which is used by the majority of modern aircrafts.Ģ staff members were married and to celebrate an aircraft drew 2 hearts. The main problem here is untimeliness of status updates (in some instances, this process is fully manual), as well as lack of transparency when it comes to what the aircraft is actually doing at a concrete moment of time.įor example, the flight status can be ‘Departed’, but at the same time the said aircraft would still be on the ground, having been queued for the runway in the taxiway for 40 solid minutes.įlightradar24 employs a different approach: it receives the flight data directly from the aircrafts. Who on Earth would need such services if anyone can go to the airport’s website and check the flight status on their own?įlightradar24 employs a different approach: It receives the flight data directly from the aircrafts.

As a rule, the data to track the airplane is obtained from the airport website, which, kind of, undermines the entire idea. What it boils down to is the source of the data. airlines, the information may be up to date, but for other countries it is not always the case, and many airports or airlines might not be included into the system at all.

However, most of them do have updatability problems. Lately, there’ve been many flight-tracking services emerging on the Internet. Since it happens a couple of times per week, alerting your Mom every single time would be ridiculous – but let’s not tell my Mom that.įor worried parents or confirmed aerophobs, Flightradar24 would be a great solution: This service lets you know what’s happening to any particular aircraft. “Call me as soon as you land,” my Mom instructs me every time I fly.Īnd she gets pretty mad if I fail to mention that I plan to fly in the first place. Many people are very anxious when it comes to flying, even if they are not the ones on board.
