You will probably not be a lifer on your run you have correct? So, why are you arguing against trying to make 135 regs safer?
Right now, companies (trust me on this one) say, well it's legal (or a gray area, so we say it's legal) so go do the trip or we find somebody else. If it is clear cut illegal, then they have no leg to stand on. You will appreciate it more when you branch out to other areas of flying if you stay 135. I know it will suck for you now since you may take a pay hit, but it will be worth it when you don't have a day off from 17 Jan until 17 Jun if you really get into on-demand. I personally went 3 1/2 months without a day off. Running on a set run is nowhere as demanding as getting called any time, day or night, for days on end.
Also, another thing...you know they can give you "a day off" while you are on a trip right now, don't you? There's nothing saying you actually have to be home for a day off. They never tried that with me but others have had it happen.
I'm not arguing against safety, I'm arguing against duty time requirements taht I don't think match the mission of 135. I don't think a blanket reform of the type that will affect 121 is necessarily the best bet for 135. I don't think that that is the way to go. Colgan 3407 was pilot error, error in judgment, error in planning, error in professionalism. If they would have said, "put another crewmember on, I'm not currently capable to make this flight," I'd be willing to bet things would've turned out differently.
Frankly, its the weather that gets them. Not necessarily the fatigue (though that is a contributing factor). First major commercial airline accident in how many years and we jump all over duty time regulations, not crew training, wx minimums, and experience requirements. I don't think that the prescription fits the disease.
When I worked at ACE, I'd have a 3 weeks to a month without a day off, yeah, it sucked, yeah, it definitely reduced my effectiveness as a crewmember. Had I been a little bit more experienced, I would have decided against taking some of the trips, and face the consequences. Now, if I don't get adequate rest, I don't take the trip. Period.
Really though, what you say makes sense, and I tend to think we're both on the same side of this, we're just looking at it with different perspectives. Personally I'm totally fine with 14 duty days, however I see your point and would rather have regularly assigned "rest-periods" for "float-pilots" or guys who are on demand who don't operate within a specifc period of time.
The problem is the FARs are vague in its certification types. On-demand, eligible on-demand, and scheduled service don't necessarily cover all of the types of operations that are required. I'd rather see a change to the rules that would precipitate the creation of Feeder Service, Scheduled Freight, On-Demand Freight, On-Demand Pax, Medevac, Scheduled Pax, and Ad Hoc of some sort. Where a Feeder Service could only carry cargo under contract from a parent company, Scheduled Freight (a la airnet or flight express or AmFlight in certain cases) would be just that, scheduled freight service, etc. Then you could create regularly assigned duty periods for the sectors of 135 that warrant regulation in that respects, and leave alone the other types. I don't know, look, I want to keep making money, but I see that guys could get pushed into it, so lets find some common ground here. Maybe making a "daily wage" mandatory for all crewmembers? Daily wages are great because you want to fly (that's what we do for a living after all) but you're not a slave to getting hours in before the end of the pay period.
