Oddball FAR Question

[100LL... Again!]

Quite a few operators are not authorized to use the takeoff alternate rule, basically negatiing any takeoffbelow 1/2 mile if an ILS is available, or 1 mile elsewhere.

135 class G ops are different than 121.

Wow a lot of thoughts here on this one. I think the conflict is because every 135 operator in the op specs has it differently stated what kind operations it can do.
For us it is basically stated that you need to be able to t.o. with whatever it takes to get back in. Visiblity is the only controlling factor on what you need to shoot an approach.
So if it served with only a GPS app. (non-precision) you most likely will need 1 mile. If it serves and ILS app. you can take off with 1/2 mile. Ops specs depending on who you fly for 135, have different variations of this due to how they want there pilots to fly. It is basically set up for people flying twins....i.e. lose and engine on t.o. and can you get back in.
the only places where I know you can take off with less than 1/2 mile would be at large airports that serve quite a system of runway lights and RVR.
Since most 135 flyers are not planning on landing at the airport they depart vis. is the only thing you need to depart.
Your dest. is going to need the ol 123 rule and let's not even get into right now what you need to be able to use an alt on a flight plan for 135 flying.
Remember all of this is hypotheitcal once you get to your dest. you use whatever the app plate says you can use. And remember the only deciding factor as to whether you can shoot an approach is what??????.....that's right VISIBILITY!
Hope this helps out. If need be I can snap out my ops manual and scan what it says.

So much easier for us Part 91 guys: Get your clearance and void time on the phone, take off at this Class G airport zero-zero in the soup if you want, and that's it. Just make sure you assure yourself of terrain and obstacle clearance..... cuz no one else is gonna do it for you!
