Frequently asked questions

What is the difference between the yellow and the orange planes?

ADS-B and MLAT data that is processed in real time is shown with yellow aircraft symbols. FAA data that is processed with a 5 minute delay is shown with orange aircraft symbols. Please read How it works for information about how Flightradar24 works.

I was following an aircraft when it suddenly 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. Please read How it works for information about how Flightradar24 works.

Can you help me find flight xxYYY?

When watching the live map there is search field just below the Flightradar24 logo. Please use it to search for a flight number or callsign of the flight you are looking for. There could be several reasons why a flight can't be found. Either it has not taken off yet or already landed. Also not all aircraft are equipped with a correct transponder to be able to be tracked by Flightradar24, or the flight could be flying out of coverage for our 3,000 receivers. Please read How it works for information about how Flightradar24 works.

Flightradar24 support can't help searching for individual flights or aircraft.

What is the difference between a callsign and a flight number?

There are 2 big aviation organizations - ICAO and IATA. ICAO handles aviation in general including navigation and technical issues. IATA is handling the commercial side of aviation including flight tickets. That means that in most cases a passenger airline ticket is sold with IATA standards/rules, for example DL-flight number from LHR to JFK, but the pilot is flying the aircraft with ICAO standards/rules, which means he is flying with DAL-callsign from EGLL to KJFK.

Most airlines have both a 3-letter ICAO-code (used for callsign) and 2-letter IATA-code (used for flight number). Charter airlines and business jet operators in most cases only have a 3-letter ICAO-code (used for callsign), as they are not selling any flight tickets so they don't need a flight number. Small/Private aircraft in most cases don't have an airline code and use their registration as callsign.

Most airports in the world have a 4-letter ICAO-code but only airports handling passenger traffic have an 3-letter IATA-code.

What are the blue points on map?

The blue points marks airports in areas where Flightradar24.com normally have coverage. You can click on an airport marker to get arrival and departure boards for that airport. The airport marks can be removed in settings. Please note that there are many thousands of airports around the world, and in order to keep the map clean we only plot airports with regular passenger traffic.

Why is the route information not correct?

The route is not transmitted from the aircraft. Flightradar24 is using the callsign of the flight and compare it with big databases of airlines schedules to find the matching flight number. With the flight number we show the route of the flight. There are many reasons why a route can be incorrect for example wrong callsign typed in to the transponder, error in some of the schedule databases, long delay of flight which makes the schedule data match against wrong flight, or some other matching problem.

Why don't you show routes for all flights?

The route is not transmitted from the aircraft. Flightradar24 is using the callsign of the flight and compare it with big databases of airlines schedules to find the matching flight number. Not all airlines are submitting their schedules or we have failed to make a match for some reason, for example due to incorrect callsign or delayed flight.

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.

Is it possible to see history of flights on Flightradar24.com?

Yes, press 'Playback' in sidebar to view global flight history from the last 7 days. You can also find history about individual flights and aircraft from the last 7 days in our aviation database.

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 3,000 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 :)

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. Please read How it works for information about how Flightradar24 works.

When will all aircraft be equipped with ADS-B transponder?

There are different regulations in different areas and for different type of aircraft. Most aircraft in Europe and North America should be equipped with ADS-B by year 2020.
