Does Flightradar24 show all aircraft?

While it may sound shocking to some, the simple fact is that some aircraft may simply not have their transponder on, or it may be temporarily off, or they may be carrying passengers or cargo, which warrant deactivation. In addition, not all airspace activity is always relayed to FlightRadar24 at all times.

Military aircraft in particular are exempt from many civil rules and regulations which would see most aircraft having an active transponder and of course their operational requirements will dictate they often do. That said, ultimately, any plane CAN disable it if they wish.

Not all helicopters are equipped with transponders, which are devices that transmit information about the aircraft's location, altitude, and speed to air traffic control and other aircraft. Without a transponder, the helicopter's flight cannot be tracked by flight radar or other tracking systems.

Information about a small number of flights may be limited or blocked based on requests from owners or operators via third-party services, such as the FAA LADD. Some high profile aircraft, such as Air Force One are not displayed.

Red: When an aircraft is displayed as red that means that you are currently following that specific aircraft on the map or that the aircraft's transponder is squawking an emergency code. These codes are 7500 (Hijack), 7600 (Communication Equipment Failure), 7700 (General Emergency)

FlightRadar gives detailed information about all flights in the near future and the past while Plane Finder shows flights which have departed and are in the air. You can't see flights in the future. A point for FlightRadar. Plane Finder allows you to set multiple Filters at once, FlightRadar doesn't.

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.

From 3 March 2020, ADS-B data collected by satellite was made available to all users. Aircraft located using satellite data are coloured blue on the map, and yellow if located by terrestrial receivers.

Orange: The flight is estimated to be delayed or was delayed.

Why can I see some planes but not others? Many smaller and older aircraft are not yet carrying the required transponder equipment so are difficult to track. Our MLAT technology can overcome this and is constantly being developed. This will help us to track even more aircraft types.

A Squawk 7700 indicates an emergency. This can be an emergency of any kind. Pilots may input it into the transponder themselves – or when instructed to do so by ATC. As a result, ground control will know that the aircraft is dealing with a serious issue and needs help.

MORE DETAILS

If a crew resets their transponder to the emergency code of 7700 (squawking 7700), all air traffic control facilities in the area are immediately alerted that the aircraft has an emergency situation.

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 100 km (55 miles) off. In settings there is an option to set for how long time you want to see estimated aircraft on map.
