I have had ongoing conversations with my local Senator's (Tim Scott) staff about Congress or the FAA imposing regulations based solely upon the arbitrary 55 pound limit they have been discussing. As technology advances lightweight aircraft will be able to handle some of the same tasks as today's much larger UAS can handle. For example, look how camera and video technology has advanced in the last 20 years. Remember the bulky camcorders we used to carry around for video?
I have asked that commercial UAS regulations also take into account the task of the aircraft and not just the size of the aircraft. If I want to sell photos and videos taken from my Phantom I should not have to face the same licensing and restrictions as Amazon does flying heavier payloads. Even if I fly a larger UAS I should not have to adhere to the same regulations as someone flying cargo if I am only taking photos and video. I compare this situation to VFR and IFR pilot licenses for small aircraft, then additional licensing and testing required to fly larger aircraft.
I have also discussed with Senator Scott the need for an additional classification and regulation of UAS under 10 pounds (with payload). Unfortunately I think that Congress will ultimately impose blank regulations for commercial UAS over 55 pounds and under 55 pounds regardless of the task they serve.
Lastly, I have discussed the fact that despite our laws regarding licenses to operate cars and trucks there are still plenty of people that drive without a license and plenty of people that have a license but still drive in an unsafe manner every day. Enacting strict regulations on UAS will not deter idiots from flying like idiots. What we need are common sense laws for a wide range of classifications and stiff fines and penalties for those that ignore the laws. Don't kill the hobby, the industry, or the commercial possibilities.
