I just got my 333. The biggest hurdle is getting in the que in time. My company some how did not get through the docket office in a timely manner. Apparently this is an issue that happens to 1 out of 50 petitions. I had seen people get theirs before mine and had submitted two months after me. Also if you are looking to do closed set motion picture filming, they scrutinize the petition further. The good thing we did, was we referenced every aircraft model that we requested with an existing petition number from another company. The FAA seems reasonable on this, as I did not have to submit manuals for every model that was already granted. The FAA considers for example the Inspire 1 and Inspire 1 pro as the same aircraft. The AFS-80 people get that most of tehse systems are not always standard so you do not need to specify if you are using a Cinestar 8 with Tiger motors vs KDE. They leave it up to your discretion to insure that it is flight worthy. On another note. I went to the Society of Aerial Cinematography conference at the Abelcine shop in Burbank this past Sunday. They had keynote speakers such as Jonathon Ruprecht, a big UAS attorney and the ICG rep, Michael Chambliss. According to the ICG, DGA and MPAA, when the NPRM 107 comes out. Closed set union productions will still require the pilot to have an FAA certificate. As far as they are concerned when dealing with talent and crew safety, they have no patience for the "Best Buy Dronogarapher."
