Igniter can be left in ON position after start as it only will operate with starter. Maybe the selection at 12% avoids a hot start from wet combustion section? AG Model PT6’s have high TBO’s and some run on diesel in certain circumstances.
Lots of helicopter PT6 out there without FADEC. 212/412?
AC did you mean “The Big Fella’s” B model?
I agree that the 12% could prevent that from happening, but if thats the case then why isn't the same when installed in a 212/412 for example.
AG PT6's only have high (on condition) TBO's in the US and 212's are routinely operated on winter diesel in northern Canada.
