Flight tracks show recorded paths built from successive position reports. Gaps occur where data is unavailable.

Traffic density highlights where more positions were recorded. It does not equal the number of distinct flights.

Observed activity is grouped into broad categories using registration information, operator records and other reference data.

Commercial — airline, charter and other commercial activity.
General aviation — private flying, recreation and training.
Public service — emergency response, rescue and firefighting.
Government / Military — government agency or military aircraft.
Unclassified — not enough information for a reliable category.

Classifications are indicative and may reflect an aircraft's registered operator or typical use rather than the purpose of an individual flight. Recorded activity depends on receiver coverage and is not a complete record of all flights.
