I am always respectful of flying my P4Pro below 400 feet. However, sometimes I see some helicopters around that seems so close. Does anybody know if they have to fly above 400 feet? I guess they also have rules.
"the onus is on us to see and avoid other aircraft. " And it's the law.Since we (sUAS operators) are allows suppose to have our aircraft within line of sight the onus is on us to see and avoid other aircraft. I think in the vast majority of cases someone flying a manned aircraft is not going to see a sUAS operating, especially if the sUAS is operating at the same or a lower altitude.
That said it is a pucker up moment when you hear those rotors but don't yet see the helicopter and you only have a general idea of direction and no idea of altitude. My thinking would be that if you're at the maximum 400' start descending as low as you can go without hitting some obstruction and keeping the drone in sight. The chances of an incident probably decrease as the altitude of the sUAS decreases.
Must yield doesn't mean move or land. You evaluated the potential conflict and made an aeronautical decision it would be safer to maintain position than to move. IMHO opinion you "yielded."The "Must Yield" phrase is is a nice thing for the FAA to add to a regulation but not always practical. As an example I will site an experience I had. Flying an Inspire 2 at 350 feet with a clear line of sight between myself and my Inspire I heard a low flying helicopter copter approaching without any idea of its direction or altitude. Visually I could not see it, I was below the tree line and could only see outward in one direction. I literally had 20 seconds to react. My decision was to stay in the same location I had the Inspire located while doing a 360 pano. The mosquito control helicopter was at about 125 feet above the ground. I could see it fly between myself and Inspire. If I would have descended I most likely would have descended into the helicopter. The NOTAM I had placed for the exact time and location did absoulutly to help with flight safety.
That is true, but the approach altitude should. I do understand the med flights are critical so the pilot is wanting to get on site asap, and back to the hospital the same. It is like if I'm making a VFR approach I maintain 1000 feet AGL on my down wind and then start my decent on the base, on strait in approaches I follow the glide slope, it is just good safe practices. On ILS approaches I stay just above the glide slope, again good safe practices.Minimum altitudes do not apply to take off or landing.
