Every record passes the plausibility guard and requires corroboration: coherent trace neighbours, or both contact endpoints in agreement. An isolated point is never elected. Candidates discarded for lack of corroboration: 2,343.

Contact time

Duration is the time between the first and last received messages: the station measures its reception, not the flight. Scope: confirmed contacts, inconsistent dates excluded.

Duration distribution

Cumulative contact time since 2016 : 6,261,764 h (of which confirmed contacts : 5,799,343 h)

The longest-contact record is under review: each candidate is verified individually before publication.

ADSB adoption, by category

Share of contacts carrying at least one position, per year, a proxy for ADSB equipment. As the raw messages were not kept, this share is rebuilt from the position counter alone.

Unconfirmed captures

4,807 aircraft whose contacts never reach the quality threshold: too few positions, too short a contact, no callsign. These rows stay in the log, out of the rankings. They document the limits of reception, often an address corrupted by a transmission error.
