Flightradar24 - Flight Tracker

Frequently asked questions

I was following an aircraft when it suddenly disappeared, why?

In most cases, our receiver network is no longer receiving a signal from the aircraft. This tends to be more common when an aircraft is flying over large bodies of water. It can also be a technical problem somewhere. Once the aircraft flies over an area with coverage again, tracking will be resumed. Coverage in the same area can be different depending on data source and transponder type.

Can you help me find a flight?

Find flights by searching for a flight number, call sign, or registration. There may be several reasons why a flight cannot be found. Either it has not taken off yet or has already landed. Also, not all aircraft are equipped with the correct transponder to be tracked by Flightradar24, or the flight could be flying outside our coverage area.

We are unable to assist in searches for individual flights or aircraft.

Do you know why a flight is or was delayed?

In some cases, we receive advance delay information, but we do not have any information about reason for the delay. For all questions about delays please contact the airline or airport directly. We are unable to issue flight delay certificates.

Is it possible to see playback of past flights?

Yes, playback is available for individual flights in our mobile apps and also on our website. To see individual flight histories, select or search for a flight or aircraft and choose the particular flight that interests you.
How far back in time you may go depends on your subscription level. All users have free access to 7 days of flight history, Silver subscribers may access 90 days, Gold subscribers 365 days and Business subscribers up to 730 days.
On our website, we also offer the possibility of using the Global playback feature, which allows you to choose a particular area on the map, date and time to view tracked aircraft. We are unable to assist in searches for historical flights.

What is the difference between a call sign and a flight number?

There are two main international aviation organizations. The International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA). ICAO is a part of the United Nations and is responsible for navigation and technical issues related to flight. IATA is a trade association responsible for managing commercial flight areas, such as 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 flying with call sign DAL from EGLL to KJFK. Most airlines have both a three-letter ICAO code (used for call sign) and two-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 call sign) as they are not selling tickets and don't need a flight number. Small/Private aircraft in most cases don't have an airline code and use their registration as call sign. Most airports in the world have a 4-letter ICAO code but, generally only airports handling passenger traffic have a 3-letter IATA-code.

More information about alphanumeric call signs is available on our blog.

What are the blue points on the map?

The blue points mark airports with regular and daily scheduled passenger traffic in areas where Flightradar24 normally has coverage. You can click on an airport marker to get an arrival or departure board for that airport or see information about aircraft currently on the ground. Detailed current weather information for the airport is also available. Airport marker visibility may be adjusted in settings.

Why aren't all airports marked with a blue point?

There are many thousands of airports around the world. Showing all airports would completely cover the map in airport pins. The primary feature of the blue point is the possibility to click and show the arrival & departure boards.
In order to keep the map clean we only plot airports with regular and daily scheduled passenger traffic. Some airports that are not yet added to our main map due to insufficient scheduling information, can still be found by replacing the IATA code on the airport’s URL. Please check the following example:

Why is there a flight missing from the departure or arrival board?

Flightradar24 combines data from several sources including schedule and flight status databases from airlines and airports around the world. These databases include most regular and scheduled flights but some minor airlines and charter airlines may be missing. Flightradar24 is working continuously to acquire as much route data as possible.

Why is the route information incorrect?

The route is not transmitted from the aircraft. We are receiving the call sign of the flight from the aircraft and comparing it with large databases of airline and airport schedules to find the matching flight number. Once the call sign is matched to a flight number, we are able to show the route of the flight. A few reasons why a route may be incorrect:

  • Changed flight plans
  • Wrong or old call sign typed into the transponder
  • Error in some of the schedule databases
  • Long flight delay, which makes the schedule data match against wrong flight

Why don't you show routes for all flights?

The route is not transmitted from the aircraft. We are receiving the call sign of the flight from the aircraft and comparing it with large databases of airline and airport schedules to find the matching flight number. Once the call sign is matched to a flight number, we are able to show the route of the flight. Routes may be missing if an airline has not submitted a flight schedule or we have failed to make a match for some reason, for example due to incorrect call sign or a severely delayed flight. Many delivery, positioning and charter flights may be missing route information as this data is often missing in the databases that we use. We are working continuously to acquire as much route data as possible.

Why can’t I see certain oceanic tracks?

The North Atlantic tracks are not active 24 hours a day and are shown during periods of track validity. The day-time (westbound) tracks are valid from 11:30 UTC to 19:00 UTC. Night-time (eastbound tracks) are valid from 01:00 UTC to 08:00 UTC. The text for the current North Atlantic Tracks may be viewed here.

Why did it look like the aircraft landed outside the runway? Has it crashed?

An aircraft’s ADS-B transponder is transmitting the position from the on board flight computer, which in most modern aircraft comes from GPS data and is very accurate. On some older aircraft (for example some older A300, B737, B757, B767 and RJ100) the position is calibrated on ground before take off and after that the current position is calculated based on speed and direction of the aircraft. When flying for some time, in wind or in circles, the calculation becomes increasingly worse, which at landing can give position calculations that are up to 10 km incorrect.

Why is aircraft data incorrect or missing?

Flightradar24 has an extensive database detailing aircraft registration, Mode S address, age, aircraft type and more. Due to the large volume of data and continual updates there are occasionally minor inaccuracies. If you'd like to submit aircraft details corrections, please do so by posting the corrections directly on our Forum thread below:

I own an aircraft but I cannot see it on Flightradar24. What can I do to have it displayed on Flightradar24?

There are a few reasons why your aircraft may not be shown. First, the aircraft may not be fitted with an ADS-B transponder, meaning it is not compatible with our receiver network. Second, if the aircraft is fitted with a Mode S transponder and not visible, it may be flying in areas with little or no MLAT coverage. Third, the aircraft might be flying outside of our network in areas where we have little or no ADS-B coverage. Fourth, the aircraft may be blocked in our system by the owner or operator.
It’s also possible that we have not yet received some details on the aircraft and therefore it’s not yet in our database. To add the aircraft to our database, please submit the aircraft details directly via the Forum Thread below, following the guidelines provided in the first post.

Why don't you have coverage in my area?

Flightradar24 coverage is only available in areas where someone has installed an ADS-B receiver and shares data with the Flightradar24 network. We are unable to provide coverage in areas where no ADS-B receivers are installed.

How can I increase coverage in my area?

Much of the coverage on Flightradar24 is based on flight data from so called ADS-B receivers around the world. If you want to improve the coverage in your area, you can apply to host a free receiver from us on the Flightradar24 website using the following link (https://www.flightradar24.com/apply-for-receiver).
If you already own an ADS-B receivers, you’ll find instructions on how to share your flight data with Flightradar24 on our website or using the following link (https://www.flightradar24.com/share-your-data).

Can you cover my area please?

We’re progressing towards our goal of global coverage. You can help us achieve that goal by hosting an ADS-B receiver. To learn more about how you can host a receiver, see 'How can I increase coverage in my area?' above.

What is the coverage area of an ADS-B receiver?

Coverage depends on many different factors. The antenna needs to be placed as high as possible with free visibility 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 well-placed installation.

Last week Flightradar24 had coverage in my area, but not any more. Why?

Flightradar24 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 could be offline. There can be a technical problem with the receiver, antenna, or Internet connection. There is also a possibility that the owner of the receiver has closed down their receiver. With over 13,000 receivers connected to the network, Flightradar24 cannot tell why different receivers are offline, and when they will be back online. If you want to ensure coverage in your area, see 'How can I increase coverage in my area?' above to learn about hosting a receiver.

Where do the photos of aircraft displayed on Flightradar24 come from?

Photos displayed for each aircraft come from JetPhotos. If you’d like your photos to appear on Flightradar24, please submit them to JetPhotos.

Why is Flightradar24 showing an incorrect photo of an aircraft?

Photos of aircraft on Flightradar24 are not hosted by Flightradar24, but come from the separate JetPhotos catalog. The latest photo available for that registration in the JetPhotos catalog is shown when selecting an aircraft of Flightradar24. In some cases, registrations are reused and there may not be an updated photo immediately available on JetPhotos. You can help make sure all photos are up to date by submitting your aviation photos to JetPhotos. Learn more about uploading to JetPhotos.

Why is the registration on the side view image visible for blocked aircraft?

The side views are an illustrated example of the aircraft model and the visible registration is just an example. The actual registration of the aircraft is not shown.

I uploaded a photo of an aircraft to Jetphotos, why is it not showing on Flightradar24?

All photos go through a screening process where the JetPhotos screening team will ensure that photos meet the required JetPhotos standards. If your photo has not yet been screened it will not be displayed. Flightradar24 displays the newest photos (sorted by photograph date) to ensure that latest photos of an aircraft are displayed to users. Photos not showing the paint scheme completely, such as silhouettes and close ups will be excluded. Some photograph categories are also excluded from display on Flightradar24. For example, any photographs that are categorized as "cabin", "wing view", "cockpit", or "exclude from Flightradar24" will not be shown.

Who produced the side views that show up for certain aircraft?

Why does the aircraft’s trail change colour?

When you click on an aircraft icon, the path that this particular aircraft has taken is displayed on the map. The color of the trail behind the aircraft differs depending on the altitude the aircraft had at that position. The numbers are in meters. If the aircraft is below 100 meters in altitude, the trail will be white. If it is above 100 meters, the trail will yellow, and with increase in altitude, will be green and so on. If the aircraft’s position surpasses 2500 meters in altitude, the trail will be light blue, and will then change to dark blue, purple and finally red for the highest possible altitude. If the trail is a black dotted line, the aircraft is outside our coverage area and its position is being estimated.

Why are some aircraft shown as blue, yellow or red on the map?

Blue: Aircraft displayed as blue icons are currently being tracked via satellite. Satellites are collecting the ADS-B signals from aircraft and transmitting them to the Flightradar24 network. Space-based ADS-B tracking will be used to supplement our terrestrial receiver network.

Yellow: Aircraft displayed as yellow icons are being tracked via our terrestrial receiver network or are in an estimated position.

Red: When an aircraft is displayed as red that means that you are currently following that specific aircraft on the map or that an emergency squawk is on for this aircraft.

How does space-based ADS-B work?

ADS-B signals are sent out from the aircraft and collected by satellites orbiting the earth. The signals are then transmitted to ground stations and the Flightradar24 network. All of this occurs in near real time.

Why use space-based ADS-B?

ADS-B signals have a limited range and terrestrial stations are incapable of coverage over the oceans and in remote areas without power and internet. Using satellites to collect ADS-B signals allows us to cover these areas efficiently and supplement our existing world-leading terrestrial receiver network.

Do you still need terrestrial feeders if you have now have spaced-based ADS-B?

Yes. Expanding our terrestrial network is vital in our continuing quest for global, multi-source flight tracking coverage. We see space-based ADS-B data as a complement to our current receiver network, not a replacement.

What is the latency of the space-based ADS-B signal?

The latency of each position varies depending on a number of factors. Any outdated data is discarded and only near real-time aircraft positions for space-based ADS-B are shown.
