IMHO it doesn't matter what kind of engine you have - at the
moment you reach for the start button of any motorised glider
you have to be 100% certain in your mind that it will not start
and have planned for that possibility. Then its nice when it does
start.

The actual probability of the engine not starting may vary
depending on the type and service status of the engine system
but the short term internal mental tool of 100% certainty of non-
starting should not.

(Even with the FES)
