Long weekly series

Each bar is one week: the region's affected-aircraft share (oldest to newest). Grey bar: not enough data that week (“no data” does not mean calm). In early 2023 the eastern regions were not yet observed, so the low share then reflects coverage, not safety.

Integrity drop events with medium or high observation sufficiency for Balkans, year by year (from the days in the archive).

Year	Events	Days with events	Observation level
2023	3	3 / 318	%43 · Moderate
2024	12	11 / 366	%65 · Moderate

The observation level is that year's observed aircraft-hours as a share of today's level. As the adsb.lol receiver network grew, observation grew; event counts in low-level years cannot be compared with today's. An event is one cluster of adjacent cell-hours: several unconnected clusters on the same day count as separate events and midnight splits an event in two, so the event count is not a number of separate incidents. This is not a trend or risk claim.

Airspaces covered (FIR): Tirana (LAAA), Zagreb (LDZO), Athinai (LGGG), Sarajevo (LQSB), Skopje (LWSS), Beograd (LYBA)

Affected aircraft: an aircraft reporting low integrity (NIC) in a significant share of its reports in a cell. The rate is computed from the daily cell-aircraft totals of the region's airspaces (FIRs); regions are groups of airspaces, not land borders.

Based on observed ADS-B data; not an operational navigation source. It does not state a source or cause. See the methodology page for the general framework.

Data: adsb.lol (ODbL)
