Flightradar24 uses colors for different meanings: aircraft icons show tracking source (blue for satellite, yellow for terrestrial/estimated, red for selected/emergency), while flight trail colors represent altitude (white/yellow/green/blue/purple/red for increasing height) or status (gray for scheduled, orange for delayed, red for significantly delayed/canceled).
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.
• Green: The flight is estimated to be on time or has arrived on time. • Orange: The flight is estimated to be delayed or was delayed. • Red: The flight is or was delayed by more than 45 minutes, or has been.
Aircraft located using satellite data are coloured blue on the map, and yellow if located by terrestrial receivers.
What do the colors of the lines on my profile map mean? White line = future flight, orange line = 1 flight, red line = 2 flights. Then it becomes blue, and eventually black at 10 flights.
• White: Below 100 m. • Yellow: Above 100 m. • Green to Light Blue: Increasing altitude. • Dark Blue, Purple, Red: Highest altitudes (above 2500 m) A black dotted line means the aircraft is outside our coverage area and its position is being estimated.
The initial information provided by Malaysian authorities led to confusion about the possible location of the aircraft. The last ADS-B position report from the aircraft was received by Flightradar24 at 17:21 UTC (1:21 AM local time), about 40 minutes after the aircraft departed Kuala Lumpur.

Our categories include Passenger, Cargo, Military and Government, Business jets, and many more pre-made filters.
For aircraft without a known destination, positions are estimated for up to 10 minutes. The position is calculated based on many different parameters and in most cases it's quite accurate, but for long flights the position can in worst cases be up to about 200 km (110 miles) off.

High-profile aircraft, like Air Force One, are not displayed. Military and government aircraft may also be blocked entirely.
For flights that are no longer in our coverage area, we may estimate their position for up to 240 minutes. These flight tracks are shown as black dashed lines. Read more about estimated positions on Flightradar24.
Popular tracking services for private jets include FlightAware, Flightradar24, FlightStats, and FlightView, which cater to a variety of user needs. Advanced flight tracking platforms now offer real-time data powered by a network of ground-based and satellite receivers.

Red aircraft icons indicate one of two things: – You have selected the aircraft and are currently following it on the map. – The aircraft's transponder is broadcasting an emergency squawk code: • 7600 – Radio failure (lost communication) • 7700 – General emergency.

If an aircraft suddenly disappears from Flightradar24, it's usually because our system is temporarily unable to receive its signal. Common reasons include: Coverage gaps: Aircraft may pass through areas with limited or no receiver coverage, such as oceans, remote regions, or mountainous terrain.
There are four types of inflight aviation weather advisories: the SIGMET, the Convective SIGMET, the AIRMET, and the Center Weather Advisory (CWA). All of these advisories use VORs, airports, or well-known geographic areas to describe the hazardous weather areas.
In aviation, squawk code 7700 is the universal transponder setting for a general emergency, immediately alerting Air Traffic Control (ATC) that an aircraft needs urgent assistance, similar to a "Mayday" call, used for issues like engine failure, medical emergencies, or onboard fires, making it a high-priority target for controllers. Other emergency codes include 7500 (hijacking) and 7600 (radio failure).
The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology. Other examples of stealth aircraft include the B-2 Spirit, the B-21 Raider, the F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, the Shenyang J-35, the Sukhoi Su-57 and the Bayraktar Kızılelma.
For smaller drones, Flightradar24 uses data from the Open Glider Network (OGN), a platform for tracking gliders, drones and other smaller aircraft. OGN uses several tracking technologies including FLARM, which is in essence a simpler version of ADS-B.
Specific numbers have specific meanings, allowing ATC to quickly understand an aircraft's situation. ❗️The 7700 is transmitted when there is a "general emergency" onboard which could be any kind of issue, from minor things like an electrical fault, to a more serious situation like engine trouble or a medical emergency.
It's not usually visible on Flight radar 24. You can usually find it on ADS-B Exchange searching 92-9000 There are dropouts in coverage over the ocean.
Yes, Flightradar24 is legal for public use, as it aggregates publicly available flight data from radar and aircraft transponders for tracking, serving millions of users and aviation professionals for purposes like checking delays. While tracking is generally permissible, some privacy concerns exist for private aircraft, and Flightradar24 offers options to block certain data under programs like the FAA's LADD to address these issues, making it a widely accepted tool in aviation.
Signals thought to be from the plane's black box turned out to be from other sources and no wreckage was found. The first confirmed debris was a wing fragment, known as a flaperon, discovered on remote Réunion Island in July 2015, with additional fragments later found along the east coast of Africa.
It's been 10 years! Today in 2014 (exactly 10 years ago), Malaysia Airlines Flight MH370 lost communications and disappeared from radar less than an hour after taking off from Kuala Lumpur enroute Beijing, China. The last words heard from the aircraft were "Goodnight Malaysian three seven zero".
While Flightradar24 is popular, alternatives like FlightAware, Flighty, and ADS-B Exchange are often considered better depending on your needs, with Flighty offering superior delay predictions and traveler features, ADS-B Exchange showing unfiltered military/private aircraft, and FlightAware providing solid essentials, with other options like byAir focusing on trip management and Planespotters.net for photos/data.
