Frequently asked questions
What is the difference between the yellow and the orange planes?
In addition to ADS-B data, we also display data from the Federal Aviation Administration (FAA). This data provides full coverage of the airspace above the United States and Canada. However, this data is slightly delayed (up to 5 minutes) due to FAA regulations. Because of this delay, the planes generated from FAA data are of a different color (orange) than the planes generated from real-time data (yellow).
Why don't you have coverage in my area?
Flightradar24 only have coverage in areas where someone has installed an ADS-B receiver and feeds his/her data into Flightradar24. If there are no connected ABS-B receivers in an area, then there is no coverage in that area.
How can I increase coverage in my area?
Coverage on Flightradar24.com is dependent of flight data from private ADS-B receivers around the world. If you want to improve coverage in your area, you have to buy an ADS-B receiver. If you already have an ADS-B receiver you can share your flight data with Flightradar24.com
Can you cover my area please?
Please read answer above.
What is the coverage area of an ADS-B receiver?
The coverage depends on many different factors. The antenna needs to be placed as high as possibly with free visibilty in all directions. Normally the coverage is about 150-250 km in all directions, but it's possible to have up to about 400 km of coverage with a good installation.
Last week Flightradar24.com had coverage in my area, but not any more. Why?
Flightradar24.com is a network of receivers around the world. Some receivers are online 24/7 and others are only online from time to time. There are many reasons why a receiver is offline. There can be a technical problems with the receiver, with the antenna, with the computer or with the Internet connection. There is also a possibility that the owner of the receiver has closed down his receiver. With over 500 receivers connected to the network, Flightradar24 cannot tell why different receivers are offline, and when they will be back online. If you want to be sure to have coverage in your area, buy a receiver and connect it to Flightradar24 :)
Where can I buy an ADS-B recevier and how do I share it with Flightradar24.com?

Why does the trail of the plane have different colors?
When you click on a plane, the path that this particular plane has taken is printed on the map. The color of the trail behind the plane differs depending on the altitude the aircraft had at that position.
The numbers are in meters. If the plane is below 100 meters in altitude, the trail will be white.
I was following an airplane when it seemed to have disappeared, why?
In most cases the reason is that the coverage from the surrounding receivers has been lost. It can also be a technical problem somewhere.
What are the blue points on map?
Major airports in areas where Flightradar24.com normally have ADS-B coverage. The airport marks can be removed in settings. We only plot airports with regular ADS-B traffic.
I work at an airline, and our aircraft are equipped with ModeS-transponder but not visible on your map, why?
Our receivers can receive signals from ModeS-transponders, but there is no position information from ModeS, so we cannot plot this aircraft on the map. Your have to upgrade the transponder in the airplane to ADS-B / VDL 4 to be visible on Flightradar24.com.
When will all aircraft be equipped with ADS-B transponder?
Actually we don't know, this make take several years.
Why don't you show routes for all flights?
The route is not transmitted from the airplane. The route is taken from our database based on the callsign (flight number). Today we have added about 120.000 routes into our database and we are adding new routes daily. If a route is incorrect or missing, you can submit route information by pressing the button "Report route error" in the aircraft info window.
Why is the route information not correct?
The route is not transmitted from the airplane. The route is taken from our database based on the callsign (flight number). Sometimes the pilot types wrong callsign into the transponder, or there is an error in our database. If you think there is an error in our database, you can report correct route data by pressing the button "Report route error" in the aircraft info window.
