Embry-Riddle Study Confirms Small Unmanned “Drones” Pose Increasing Risks to Aircraft
During the 13-day sampling period, researchers detected 73 individual DJI-manufactured drones that made 192 separate flights in the Class C airspace around the airport. (www.suasnews.com) 更多...

Question: Do these drones indicate actual AGL or MSL altitudes? GPS altitudes are inaccurate much of the time. Just curious.
Most of them don't have telemetry. The larger, more expensive ones do but the pilots I know seldom look at that number since the resolution on their cameras determine the altitude they need to be at to get a clear image. You don't see much detail from them at altitude. Our flying field is 3.5 miles from the local airport, we have a MOU with them, and we always use spotters when a pilot is flying FPV. Unfortunately, ANYBODY can buy one of these things, with no training or understanding of safety or regulation and that is where the problems come in.
Too bad they didn't report the number of UAS that may have been authorized by LAANC for commercial operations.
10th paragraph.
"The researchers compared detected sUAS activity with locations and altitudes prescribed by the FAA’s UAS Facility Maps. According to the FAA, “UAS Facility Maps show the maximum altitudes around airports where the FAA may authorize Part 107 operations without additional safety analysis.” More than 20 percent of the 177 flights were flying higher than the safe altitude prescribed for their operating area. Moreover, researchers compared detected UAS operations to historical manned aircraft flight data, revealing several near encounters."

Had to go to school to figure that one out?
I could see insurance companies taking note of this because while a drone strike may not always be fatal, damage is still likely and thus causing an increase in claims. I could see premiums shooting up because of findings like this one.
