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.
Aircraft located using satellite data are coloured blue on the map, and yellow if located by terrestrial receivers.
White colours indicate the plane is on the ground. As a plane takes off, the colours change from white, to yellow, to green, to light blue, to dark blue and finally to purple. You can also track the history of a past flight, by typing in the flight number. A play icon will appear beside the specific flight.
what does a red plane mean on the app? Red icons indicate aircraft that are squawking 7600 or 7700.
Websites such as ADSBExchange.com, FlightRadar24.com and FlightAware.com aggregate flight data in the United States and abroad using a mix of commercial and citizen-owned sensors that capture the movements of commercial, civilian and military aircraft in real time, 24 hours a day.
Even though our platform suffered under such heavy load, Queen Elizabeth II's final flight from Edinburgh to RAF Northolt, is by far the all-time most tracked flight on Flightradar24 and will likely remain at the top for a long while.
MLAT position calculations have a general accuracy of 10-100 meters and 1000 meters in the worst cases. If both calculated positions are incorrect, then the speed we calculate is incorrect, which can lead to a single-engine prop plane nearing the speed of sound.
Yellow: Aircraft displayed as yellow icons are being tracked via our terrestrial receiver network or are in an estimated position.
Below are the meanings behind these colors: Gray: The flight is scheduled and there isn't an additional status available. Green: The flight is estimated to be on time or arrived at time. Orange: The flight is estimated to be delayed or was delayed.
If there's a radio failure associated with an emergency, the aircraft might alternately squawk 7600 (no radio) and 7700 (emergency). This alerts ATC that the aircraft is declaring an emergency and does not have an operable radio.
Squawking 7700 in an emergency
The most well know of these is the code 7700. This is used to indicate an emergency of any kind. A pilot will enter this when in an emergency situation - either instructed by ATC after declaring an emergency or without communication if there is no time.
Purple Lights
The airline expressly forbids the use of green and blue light onboard its aircraft — it's believed to suppress your appetite — favoring instead a signature purple palette that's remarkably effective at achieving a unique sense of calm aboard Virgin's planes.
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.
The current longest flight in the world
Its longest flight path, which connects Singapore's Changi Airport with New York's John F. Kennedy International Airport, 9,585 miles away, takes 18 hours and 40 minutes. The carrier has been flying the route since 2021.
Code 7600 is the code for a loss of radio. If a pilot's radio goes out during a fight, they can enter 7600 into the transponder. Then they should proceed to their intended airport following a standard landing plan. Pilots should be extra careful and on alert for other aircraft around them in the sky.
Flightradar24 on Twitter: "@james68953a Hi James, the colored dots represent delay status: Green = on time, yellow = 15-45 min delay, red = 45+ min delay" / Twitter.
In most of these 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.
The black shows estimated positions where aircraft was out of coverage.

If a flight has an asterisk (*) next to it, it means it is currently later at the departing airport than the expected departure time and the flight is not yet active.
This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km). Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
Like FlightRadar24, Plane Finder is one of the original and best known flight tracking websites and apps. It has millions of global users and is easy to use, with lots of data. Again, it doesn't show all the military and light aircraft, but does have a lot of useful information on the aircraft it does show.
A radar system detects other aircraft, ships, or other objects and the speed and direction in which they travel by sending out a pulse of high-frequency electromagnetic waves.
It may be of interest to know that the oldest plane we track on a regular basis on Flightradar24 is this Curtiss Wright Travel Air B-4000, which is a whopping 91 years old.
