No it is not and sadly you don't really know what you are talking about. The files are neither signed nor encrypted. Not even the DCS base game files are signed which is quite concerning at this day and age.
None of the DLLs are signed.
Like @Ramsay said, its basically a cold start with the following differences:
Need to switch to the second JFS bottle by rotating the JFS switch
In my experience the throttle does not react until both engines are running again (you can observe this in the video)
You didn't mention the TPOD at all until now. Cueing the TPOD to a SP, designate and XFER TPOD is not really what I was asking and it can't be done sitting on the ramp either.
Hmm as far as I know in order to transfer Navigation Target Points these have to follow a special naming scheme like "M1.x". How do you create those outside the mission editor?
Sometimes its fine and sometimes you slowly begin to drift off center, and any correction you make, makes the problem it worse until you finally skid off the runway and crash.
