You have to be more specific than that since the rule is 5 miles for hobbyists. Whether you want to measure your mileage from the center of the airport or from the edge of the airport is another question... I would say the center since all these circles we see on the air maps are from the center.
Point taken, I was erring on the side of what is the closest that it might be.
So, if I am within the 5 mile radius, as a hobbyist am I allowed to fly as long as I notify them? If yes, then can I use the B4UFly app to submit my intention to fly, or must I call them?
