Ag machines are pretty rudimentary.

START - dry motoring run

START + IGNITER ON - start

IGNITER CONTINUOUS - self explanatory used in inclement weather conditions

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?
