If this was to be done and pass basic safety and regulations I can see a huge lists of To Do before it ever becomes public ready.
- License: I’m sure some kind of testing and level of knowledge would be required like for a motor vehicle.
- Insurance: I can’t see very many people finding a underwriter to provide coverage. Death and property damage would be a given.
- Aircraft: Whelps if history is any indicator any flying vehicle would have to show and prove it could still land with 50% loss of propulsion. Keep in mind if any of the front / back sets of propellers fail your going down and will just die.
Runtime will have to have a minimum air time based on the worst case altitude and headwinds. An emergency reserve battery system like any other aircraft must be present and operate separately from the main and can only be used in an emergency and hence will impact its mileage / distance covered.
This leads to redundancy of various systems from gyro, fly by wire, how the wiring is run etc. It doesn’t even address the need for a very expensive black box or GPS location device and tracking.
Super cool but long ways to go before any of us lays hands on one!
