3. As part of your line up checks ensure that the auto feather is armed
I call "2 off" (for the auto ignition lights) and "2 on" (for the auto feather lights) before brake release.
I have flown with quite a few colleagues who wanted to omit 2...
OTOH the A/C in question might not have had an auto feather system fitted.
I had a TRE pull the pwr off one donk on a B200 with 3 blade props just after liftoff (after briefing it`d be pulled at 500agl...) and that certainly got my attention. That was in bright sunshine and a very light A/C. I hope IŽll never have to cope with a real EFATO in darkness or fog with a heavily loaded KA without a working AF.
