Current drone flight approval and evaluation is frustrating both for authorities and drone operators as well. Every single flight plan consumes roughly 40 man hours to the authorities and spans within a week or two limiting scalability. In the future where 30,000 flights are expected only above Sofia this process is more than archaic.
Fully digitalized cloud-based partially automated flight approvals and flight telemetry data sharing speeding the process to up to minutes relieving both the authorities and the operators. Two-way communication channel between authorities / air traffic controllers / drone operators in case of need. Security and safety boost sharing flight data with whomever has the right to view it.
