Early this year the National Wildfire Coordinating Group published their standards for operating unmanned aircraft on fires.
Here is how they describe the 24-page document:
The “NWCG Standards for Fire Unmanned Aircraft Systems Operations” standardizes the processes and procedures for interagency use of Unmanned Aircraft Systems (UAS), including pilot inspections and approvals. In support of fire management goals and objectives, the aviation community references these standards to utilize UAS in a safe, effective, and efficient manner. These standards further serve as a risk assessment for fire UAS operations and meet federal requirements for aviation safety and operational planning pertaining to recurring aviation missions. Agency level policy and guidance is provided through established federal or state plans and processes.
