Only if the 107 operator maintains direct oversight of the non certificated operator. The 107 operator is the Pilot in Command, similar to how it works in full scale with a flight instructor. The 107 operator cannot oversee more than one non certificated operator/one aircraft at a time. If anything goes wrong the 107 operator will be the one held responsible. The practice has its uses for temporary pilot relief and training but in a disaster relief situation it’s more or less a waste as you want the more experienced operator with hands and eyes at the controls.
I’ve received a couple of disaster team inquiries and have attended pre deployment briefings. Those that participate as part of the team aren’t out there playing for fun. When, where, and what they shoot, along with specifics detailing how they will shoot targets is very controlled. Those invited that actually deploy have to be self sufficient in supplies and equipment for a minimum of three days. That self sufficiency includes transportation; preferably 4WD or a vehicle than can reach difficult locations, vehicle fuel, food, water, electricity, emergency medical kit, and a place to sleep. You must being your own safety equipment which will include hard hat, boots, reflective vest, traffic cones, and other items. You may end up deployed to areas without oversight or security. Your insurance for both your car and aircraft will need to be up to date and the policy limit requirements are high.
Bear in mind in such situations you will be carrying items those that have been displaced may desperately need and their desperation or those having criminal intent could try and take your supplies and equipment from you. In such situations the locals don’t care about your safety or survival, only theirs.
There’s a lot more to disaster relief operations than some may consider but one thing is certain, they don’t want anyone there that was not invited and already schooled in their tactics and communications. The time for training is before a disaster, not during one.
