Probably not much. I work at a hospital and when the chopper lands, it’s surprisingly little wind from 50-ish yds away. The wind force is diminished by something approaching distance cubed which means it drops off very quickly with distance. I should clarify that I’ve never seen a formula for this, it’s just a semi-educated guess. Pseudo-educated, maybe? 😁
if a helicopter was actually that close to the road, would you be able to feel it with your car? how far does the force from the propellers travel?
