In the age of Smartphones and other small personal digital assistant devices, flight trackers are the must-haves for people. This is because people have become more anxious about the arrivals and departures of the flights. It is due to the rise in air accidents that there has been a huge interest and requirements of improving flight tracking services.

These days flight tracking has become important for almost everyone who is travelling frequently or also for those you are not frequent. But before using the flight tracking service, it is required to understand that how it works. Here is the general process of tracking a flight online.

Receives Details About The Planned Routing Of The Flight


The details of a flight and its scheduled timing and routes are delivered to the website a year in advance via schedules published by the airlines. The data received by the website usually remains unchanged till a few hours before the flight. New data is pushed out by the pilots or air traffic control operators who are controlling the airspace on the route of flight.This data is a flight plan that includes the specific details about the altitude, planned routing and speed of the plane. But this is where the stable data end and the real-time data begin.

Getting ‘Out’ And ‘Off’ Message At The Time Of Departure

An ‘Out’ message is sent by the airline to the website tracking that flight, as soon as the door is shut down and the parking brake is released by the pilots. The ‘Out’ message indicates that the flight is pushed back from the gate, and as a result, people know that departure time is near. An ‘Off’ message is received by the website from the airline as soon as the weight is lifted off the landing gear. The ‘Off’ message indicates that the plane is in air, or it has departed.

Getting Position Updates When The Flight Is En Route


When the flight is on the way, the website keeps on receiving position updates from the flight via radar installations at the air traffic control centre. The air traffic control continuously sends updates on the position of the flight. The website then compiles all the information received. The website then uses it to estimate the flight’s time of arrival. Then this aggregated data of the flight is displayed on its website.

Getting An ‘On’ Message At The Time Of Landing

An ‘On’ message or an arrival notice is sent from the air traffic control to the website. The website also detects the landing by seeing the flight slow down below its flying speed. From there, they have surface coverage to track the landing of the flight. Then it eventually receives the ‘in’ message from the airline which indicates that the flight is safely parked at the gate.

The above process can be applied to as many flights in the sky and at any time possible. Today people are highly involved in tracking their flights and are appreciating the amount of data that the flight tracking websites’ servers and algorithms are providing each and every second.
