What is the purpose of this? Does it run automatically? Why is the default set at 33% of the original speed? Does this change actual in game time, ie, does one hour in game take three hours in real time? Does it make the planes fly slower?

My bottom line point is that I'm trying to determine if this program interferes with some time-sensitive mods like the HASP add-on RNAS6.

OK; if I am reading this correctly, it should not affect Greybeards's RNAS6 add on to HASP. As you probably know, I've been having some problems and one thing that came up is that it won't work if the game is sped up like (as I recall from the manual) is possible to get you from point A to point B faster. I think it only matters if it changes the actual speed of the aircraft in game. He's using much more authentic flight models in it and darn it, I like it (!), but the AI has been goofy since I downloaded it. I doubt it is the mod; more likly something about my computer.
