The FAA has "clarified" their stance in regards to UAS used in any SAR type of flights. Many SAR groups are putting out memos, mailings, VLOGs etc about this right now. Basically it boils down to this.... Search & Rescue is well outside of "Recreational/Hobby" flights and as such they are deemed "Commercial". This will require one of the following: FAA Section 333 Exemption (and all that exemptions requires) FAA Part 107 (remote pilot airman certificate with a small UAS rating) COA (Public Entity) If you want to volunteer your services with your local EMS groups then go ahead and get your Part 107, contact the group to let them know you are "current", offer to join, and TRAIN with them. Search & Rescue is a tightly orchestrated event which requires specific classes to be able to work WITH the team efficiently and safely. Most require FEMA's classes under NIMS: ICS-100, ICS-200, ICS-300, IS-700, and IS-800 just to be considered part of the IMT.
