Thanks for all the replies gents! I've already put all my time into LTP, so now I'm just sorting through it trying to make sense of it all and building my searches so I can slice it and dice it according to the myriad ways the various apps want to see it. It has been a real lesson in how bad of a job I did on my logbooks when just a young punk playing with some seriously fun toys...

Again, thanks to all for the replies.

For me it was not converting for the interview. I didn't. I took my flight records and an Excel printout of the totals along with my Civ logbook. It was after the fact that I started adding it all to Log 10 Pro. I want a record of all my flying when I'm old and grey. Some might not. I'd like to leave it for my kids and grandkids. Do 1 page a day and in a few months it's all in there, editable and printable.

I would join the "don't waste your time" group. From almost all the mil guys I've spoken with who have been hired, hours are only a part of the score that gets you an interview, after you actually have the interview the airlines don't care. It is a different story if the majority of your hours are civilian where the hours are scrutinized more closely.

There was one notable exception where they were playing good cop/bad cop and they chose to give a friend of mine a rash of stuff over his logbook. He still got hired, as far as we could tell it was just a tactic to try and get him defensive.

Same here.

On trips, I print out the Out, Off, On, In (OOOI) page off the FMS and fill out my log ten pro on my commute home. It's a pretty capable program. I even log my trips which then contain my individual legs. Not sure how long I'll last at this though. Last time I flew as a civilian CFI, I eventually stopped logging time at all and had to recapture about five hundred hours out of my old appointment book.

I really needed to get it all into LTP since I had different squadrons and/or duty stations logging things very inconsistently - It certainly did take a while to get it all in there, but without some kind of electronic spreadsheet (in this case LogTen Pro) it just would have been too much of a mess to deal with. For the sake of maximum clarity - but also posterity - I added all flights individually. It was a trip down memory lane!
The biggest problem I found was converting to the Civilian terminology and going through to pick out stuff we never logged specifically - like trainers that were also checkrides, and so on. This was an issue for me because I have no civilian experience. The first flight I ever did was with the Navy, so I didn't even know what a civ logbook looked like.
Everybody's answers have been helpful. Again, thanks.
