- increase in ACAS RAs and most notably false TCAS RAs recorded in 2016;
- persistent laser interference problems and attempts by some states to address them;
- increase in call sign confusions in 2016 and how EUROCONTROL’s Call Sign De-Confliction Tool (CSST) can help;

The participants in the EVAIR mechanism took great strides forward in 2016, reducing the number of days spent investigating reports from 67 days in 2015 to just 26 days in 2016 while keeping the high level of the investigation quality.
