Hour by hour: before, event, after
Hourly view of the event day: the event hours plus a few hours before and after. Values are the hourly share of affected aircraft across the whole published region network, not of the event's own cells; do not read them as the event's size or cause.
Before → Event → After. ○ no data: no aircraft were observed that hour; this does not mean zero interference.

What we do not know about this event
- Cause: jamming, spoofing or a fault in the aircraft's avionics cannot be told apart from this data alone.
- Coverage: the data comes from a single source (adsb.lol); aircraft where there are no receivers are not seen.
- Share: the affected-aircraft count is not a share of all aircraft in the region; it covers only aircraft observed in the event's hot cell-hours.
- Reality: this is an indicator; the event has not been verified by an independent source.
Method and limits
- What is this event?
- An event is a region of low navigation integrity (NIC) seen in adjacent cells over consecutive hours. It does not say what caused it (jamming, spoofing or a fault).
- What does “aircraft affected” mean?
- The number of distinct aircraft that reported low NIC in the event's hot cell-hours. It is not a count of all aircraft in the region. Observed aircraft are only those seen in the event's hot cell-hours, not all aircraft in the region. The share should therefore not be read as “the share of aircraft in the area”.
- What does observation sufficiency say?
- Observation sufficiency comes from the number of aircraft observed and the uncertainty interval of the affected share; it shows how solid the data is. It does not say what caused the event or whether it is real. A reasonable sample. “High” needs more aircraft and a narrow interval.
