Create an app that will enable small drone operators to know more about specific weather parameters, local terrain and no fly zones within a five-mile radius of their GPS location.
Imagine a network created ad-hoc for drone pilots, a net which connects all the pilots around the world and let them share, in real-time, useful information about no-fly zones, restricted areas and artificial obstacles. Each user will be able to select a place of interest and by doing that he will know if that place is a good one or a dangerous one. By using this network each pilot should write a report about the above mentioned information and additionally write something about the difficulties he faced after piloting his drone in a determinate place. Each report will be a feedback, the more positive feedbacks a place gets the safer it will be; this will help a lot, in fact a drone pilot could evaluate the place before hitting the road and know what kind of challenges he is going to face, basically if it fits his pilot skills or not. There's a ranking system which works like this: if a report gets ten or more positive feedbacks, the user who wrote it levels up and moves to the next rank, each rank indicates how trustworthy the user is. The end systems of this network will be things like smartphones, tablets, phablets, etc.
I think that this solution is both solid and reliable, in fact it mixes two well known and well working ideas: feedback and gps networking.
