Had my first NFZ snafu today. I was at the very edge of an airport advisory zone (yellow, not red)....some 8 miles from the Class D airport... this was an approach corridor, well out of the 5 mile red zone. The Djigo4 software would not allow the Spark to take off. I tried Litchi... same thing. I'm aware of how to do a self- unlock, using the DJI Geo site, but there has to be a better way.... especially when you consider that DJI will only accept unlocking requests from a PC... NOT from a mobile device. So, today, out in the field, I was SOL. This is total BS. I'm all for safety, but this stuff borders on invasion of privacy. There is a NFZ mod out there for the Mavic Pro using Asst2 for changing 2 code values, but I'm wondering about the Spark. There is an outfit called NoLimitDrones.com that for $35/drone, that will disable this, and other pesky DJI inflicted limitations. I do not ever intend to violate the law, but I found this lockdown today to be totally silly. What I intended to shoot was below 200'.....
