You would have to explain the procedures that you would use to create an "equivalent level of safety". My operations will probably be different than yours, hence the lack of guidance on verbiage from the FAA. A couple of things, without knowing how / where / when you operate: 1. Use a V/O and explain how the V/O is trained, how you AND the V/O will identify hazards a. On the ground (ie people) b. Obstacles to flight c. Manned aircraft d. Other UAS. 2. Explain how you and the V/O will communicate and what your back up communication plan is in case of failure. 3. Consider a procedure to limit the distance from you to UAS. 4. Add a requirement that all operations cease upon identification of unexpected hazard.
Additionally you will need to explain your operations in detail and to the level desired by the particular individual reviewing your waiver and the local air traffic manager. It's still a hit an miss process.
