This is not questionable, it's not a grey area. It's not difficult to understand.
Respectfully, Avbug, it *is * a grey area, and stipulating that it isn't doesn't make it so.
Let's back up a step and examine what is *not* a grey area.
If you're flying passengers IFR under 135 in a baron with no autopilot, an SIC is clearly required, no discussion.
If you are flying cargo IFR under 135 in a baron, the SIC is clearly *not* required, and you are *not* allowwed to log SIC time. To do so is clearly falsification, no matter how many checkrides you hve had. Airnet used to sell thier right seat for this purpose. They don't any more and on thier website you will now find an oblique admission that it really wasn't legal. My money is that it's a result of a little legal action from the FAA, but I digress.
So, we know when it *is* and it *isn't* legal. Let's examine the middle ground.
We're flying passengers in a baron with a functioning autopilot IFR under 135. the operator had authorization to use an autopilot in lieu of an SIC.
Is the SIC required by "the regulations under which the flight is conducted"?
That's the crux. whether you're *authorized* to act as SIC or how many checkrides you've taken is all completely irrelevant.
The only thing that counts is:
Is the SIC required by "the regulations under which the flight is conducted"?
That is the question.
There are 2 views on the matter.
One is that the SIC is still "required" by 135.101, even though the operator is authorized to operate without one, therefore it is legal to log SIC time.
The other view is that the SIC is not reqired by the regulations. This position is best summed up by the question, "can the PIC leglly make the flight if the SIC doesn't show up?" IF the answer is Yes (as it would be in our hypothetical) than the SIC is *not* required, and SIC time may not be logged.
Personally, I find the second much more compelling. It is simple and straightforward, and it doesn't depend on taking to word "required" to mean something other than it's plain, everyday dictionary meaning, and it doesn't involve placing greater emphasis on one regulation and essentially ignoring another.
So, is it a grey area? yes, without a shadow of a doubt. The FAA has never clarified this with a legal interpretation, nor has there been an NTSB decision regarding this issue. Personally I can't imagine a judge ignoring the simple, obvious test of "can the PIC legally make the flight without the SIC" but that's my *opinion* and stranger things have happened. The reality is that it is a grey area and no-one knows for sure which way a judge will decide. But without question, logging SIC time when the PIC may prefectly legally make the flight without you is treading on the very boundary of what is legal.
The fact that one has passed one, or two, or a dozen, 135 SIC checks is completely irrelevant.
