Guys there is a lot of noise on the internet. I have gone over specific topics in the 107 to find choke points where you might need to be under your 333 for a bit. 1. First off if you have the 333 and any supplemental COA 's, they are good until they expire. 2. Why would I need to use my 333 when I get my 107 ticket? Good question, the answer is airspace and closed set work under the MPTOM. Airspace: Under the 107 operating in class B through E is not going to be a simple as we thought. The coordination will be done thru a waiver portal. Based off of the language this sounds very similar to getting a special COA for the 333 guys. Example 1: On August 20th I get my 107 RPIC, hooray for me! On August 22 I have a job flying inside KABQ's class C airspace. Hmm. I just applied for a waiver for that airspace but it has not been approved yet. Darn, what do I do? Well, I have a special COA under my 333 that allows me to operate upto 1 NM of KABQ for my 333. At this time I will be doing the job under my old 333 and special COA. I will not be exercising my privileges under my newly minted 107 card. Closed set work: If you do a ctrl-f in the new 107 document, you will find out that you need a special waiver to fly for closed set work to be in close proximity to participating people. Example 2: In the first scenario, I am also doing the flight for a TV show. Darn again, I am still waiting for that waiver to go through. My 333 as well as many others have paragraph 2 that says I can fly for closed set work. Again I need to operate under my 333 for that provision. Yeay! 3. The Big Gotcha! You will not be able to mix and match provisions in both settings to suit your needs. In the above examples I am going to operate under my 333. I found out that there are some lesser strict requirements under the 107 You can fly 400 feet above a structure as long as you are within 400 feet of the structure. The 333 said 400Ft AGL period. You can now follow the drone in a car now on a rural road. Under the 333 this was not allowed at all. You do not have the arduous 500 foot rule around non participating property. You no longer need a VO Old 333's this was an option but the new ones it was mandatory. You can temporarily deviate from the LOS requirement for operational necessity as long as you can reestablish the VLOS in a reasonable amount of time. The way I interpret this is that I can do a car follow and be heads down in the glass to do it precisely. As long as the system is still visual and I can reacquire it I meet the intent of the requirement. It does not imply that I can fly the thing two miles away temporarily if I can no longer visually acquire it. In my case I will be operating under my 333. So I will not be able to use any of the less strict 107 provisions while flying under the 333. The Special COA for the 333 does not transfer to the 107. You must get a 107 waiver instead. 4. The 107 RPIC does not meet the Part 61 requirements for the pilot under the 333. Why is this important? You might be one of those entities that have a 333 but had to hire a real pilot to do the actual work. Now you can do it yourself with your 107 cert. However, if your flight can only be accomplished under your 333. You with only a 107 RPIC will not be legal to do it.
