So I'm trying to understand what kinetic energy of 11 ft/lbs and 25 ft/lbs.... Here's what I can't up with for a Mavic Air 2 at 1.3lbs... (I'm not a physicist btw).
11 ft/lbs is 14.9 joules. 1.3lbs at a velocity of 16mph is 15.1 joules.
25 ft/lbs is 33.9 joules. 1.3lbs at a velocity of 24mph is 33.9 joules.
So... Crashing into a person at 16mph is a Category 2 event, yes?
And crashing into someone at >16 but
But is the FAA talking about a freefall event?
In which case, 1.3lbs falling from 400ft reaches 109mph, which would be 700 joules or 516 ft/lbs.
Obviously this is a freefall and a drone has a significant amount of drag so it would fall slower (sorry, I don't have data for how fast a MA2 freefalls).
Pilots, please chime in.
