I know the FAA B4UFLY is the only map to worry about when it comes to no fly zones in the US. I have a question though about the DJI map at DJI - The World Leader in Camera Drones/Quadcopters for Aerial Photography. This map shows a red circle around a small local airport but the circle isn't even a 1/4 mile in diameter. So I have no issues flying around here. However, the B4UFLY app shows that airport with a 5 mile radius and also shows two other airports with 5 mile radiuses that both overlap my house. Those 2 other airports don't even exist. Never have the 40 years I've been around here. So if DJI ever syncs their NFZs with the FAA, I pretty much have a $1000 paper weight. Am I pretty much correct?
