OK. So you are flying in Class G (uncontrolled) airspace or you have requested and been approved to fly in controlled airspace (thru Low Altitude Authorization and Notification Capability (LAANC) or FAADroneZone) so you are good to go as far as the FAA is concerned, but you may also want to know who might potentially interrupt your drone flight because you didn't "pay them the courtesy" to notify them that you would be flying in "their jurisdiction".
Some of these agencies have their own active drone programs and have pilots that fly for their agency and are 107 pilots also. If your encounter is with an officer who is knowledgeable of drone laws he/she will probably ask you questions like: Are you flying commercially or recreationally? Can you show me your Pilot Certificate or TRUST certificate? Do you have approval from the FAA to fly in this area? Are you aware of how close you are to the airport or other "critical infrastructure"? Do you have approval from the landowner to fly here? How high were you flying? Do you have a waiver for BVLOS, OOP, OOMV, or other regulations subject to waiver? Do you have donuts?
If you answered "YES" to any of their questions, be prepared to show them the Certificate, authorization, or waiver. If you answered "NO" to any of their questions, be prepared for a FREE ride in their vehicle.
Other agencies are less interested in your drone approval and more interested in whether you received the landowner's approval to fly (take off and land) on their property. Nevada Revised Statute 207.200 defines the crime of trespassing as entering someone else’s property without permission or remaining on their property after being instructed to leave. Trespassing is a misdemeanor with a penalty of up to 6 months in jail and a fine of up to $1,000.00.
