US: 2017 laser incidents on pace to be lower than 2016

As of April 29 2017, there were 2,078 laser illuminations of aircraft reported to the U.S. Federal Aviation Administration. This is 17% fewer than the 2,514 illuminations reported as of April 29 last year (2016).

The chart below shows cumulative laser illuminations for the period Jan. 1 - April 29, for each of the past 10 years. The blue 2017 line shows that thus far there have been fewer incidents in 2017 than in 2016, but more than in 2015.

How to read this chart: Each year starts with 0 illumination reports. Each colored line then plots the cumulative (year-to-date) illumination reports for that year since January 1. For example, looking at the 2016 top green line, there were about 1000 reports between Jan. 1 and Feb. 14 (where the green 2016 line crosses the 1000 horizontal line). In contrast, in 2013 (purple line) there were roughly 500 reports between Jan. 1 and Feb. 14 (where the purple 2013 line crosses the 500 horizontal line).

Based on historical data, LaserPointerSafety.com projects that there will be around 7,200 laser illuminations reported to the FAA in 2017. This would be about 4% lower than the 7,442 reports in 2016, and about 7% lower than the 7,703 reports in 2015.

A separate analysis shows the number of laser illuminations for every single day between Jan. 1 2007 and April 29 2017.

In the chart below, the light blue line shows each day’s illumination reports. This number can vary widely from one day to the next. The dark blue line is a 60-day moving average; this helps smooth out the data in order to show longer-term trends.

From this chart, it can be seen that illumination reports grew slowly, or even declined, in the first few months of 2015, 2016 and 2017. However, in the final months of 2015 and 2016, the number of illumination reports picked up significantly. The estimate above (that there will probably be around 7,200 reports in 2017) takes this effect into account.

Statistical note: The careful reader will see that the 2017 blue line in the first chart falls between the 2016 and 2015 lines. Yet LaserPointerSafety.com predicts 2017 as a whole (Jan-Dec) will be lower than both 2016 and 2015. This is because we used all ten years, 2007-2016, to estimate the year-end total as a proportion of the first four months. Both a simple average of these ten years, and a weighted average — where more recent years have a larger effect — indicate that the 2017 total will be in the ballpark of 7,200 illuminations. In other words, 2015 was an atypical year where illuminations in the last eight months of the year grew much faster than any other year.
