Well, if you want to score your flight anywhere, you need to have the engine
in operation somewhere during the log so that the engine noise/vibration
sensor is verified.
You can do that after returning home, of course, but it would be more
sensible to do that before leaving.

1) Is there a good reason why one shouldn't do a runup

Yes. It has no starter. (And, btw: Even if it had one,
the simple fact
that it starts *now* doesn't mean that it will start
*then*.)

My bad - never looked closely enough at a Turbo.


2) Do many pilots flying sustainer-equipped sailplanes
presume that the engine is unlikely to start and not
care,

Yes and no. Yes, flying a sustainer we *always* presume
that the engine
is unlikely to start. And no, we actually care. Thats
why we never rely
on a ststainer but only start the engine over a landable
field.


That part I know. I was trying to ask a slightly different
question, which is: if sustainers are less reliable
on a first start than a second start and pilots don't
do some sort of runup prior to heading out on course
is it that they just don't care that much if the engine
fails to start when called upon - forcing them to land
out? Or is it that they don't believe the second start
story? Or do most pilots actually do a runup (from
an air start of course!), prior to going out on course?
