My thought exactly.

There have been some comments here that sustainers
generally are not run up prior to flights (presumably
including flights where use of the engine is a distinct
possibility) AND that periods of inactivity significantly
up the odds of the engine failing to start.

If both of these statements are true it seems that
flying a sustainer-equipped sailplane cross-country
without a preflight engine runup is a bit of a roll
of the dice. It also raises in my mind two somewhat
related questions:

1) Is there a good reason why one shouldn't do a runup
prior to every (cross-country) flight?

2) Do many pilots flying sustainer-equipped sailplanes
presume that the engine is unlikely to start and not
care, do they presume that the engine IS likely to
start (correctly or incorrectly), or do they believe
a preflight runup doesn't help the odds anyway.

Thoughts?
