Federal Aviation Administration (FAA Feed)
Not all aircraft are fully ADS-B equipped. In locations such as Europe and Australia, the implementation of ADS-B is well advanced and the majority of aircraft use ADS-B. Equipage in North America is behind currently but is increasing following the US NextGen ADS-B equipage project and the 2020 mandate.
Where we do not have ADS-B or MLAT coverage for an aircraft in North America we will supplement this using a feed provided by the FAA. The FAA feed covers US and Canadian airspace including bordering areas of the Atlantic and Pacific Oceans.
FLARM Feed (Gliders)
It is not practical to install ADS-B in gliders due to constraints of cost, weight, and power. FLARM has been developed as a situational awareness tool for glider pilots.
It is also sometimes used in some small planes and helicopters. The technology has short range and operates at a frequency of 868MHz. Plane Finder take a centralised FLARM feed.
At Plane Finder, we realise that we have a responsibility to do the right thing. We aim to deliver the benefits of live flight tracking whilst working hard to ensure that our live feeds do not include data that could compromise national or regional security.
We actively review the aircraft that we are tracking and consider all requests to block aircraft from our systems for security reasons.
