Sole manipulator? That would seem to work if you're flying from the left seat without an autopilot doing any of the manipulating. But what if you're flying from the right seat, are you also going to log the time the captain taxis the plane while you work the radios?
Fact is, you can log whatever you want. Knew a guy who had a column for logging jumpseat time. But ask yourself what am I logging this stuff for? Is this a diary or a resume reference.
Prior to gettting your ATP, you probably followed 61 and the logging of flight time for the purpose of meeting the requirements for a higher certificate or rating But you've got your ATP now; now you're logging time to show currency and also (if your smart) to help get yourself out of the fractionals. At this point, who is going to give a poop about pt61 PIC time? And if they do, you're probably worrying too much because it sounds like they'd accept anything. Best bet, set up a column for Part 1 PIC at this point. If ,and that's a big if, you're ever ask to produce the time pt61 allows, you can always go back and add based on the legs you flew. But don't mess up your previous entries to log an entirely new way.
How are you logging cross country time? As required before your Private or as they allow once you've got your Private and you're going for your Commercial? You know all those flights between airports that didn't meet the requirement for cross country prior to getting you Private can now be counted. Does anyone care!?!?
