Is it common in jet or turbo-prop aircraft for manufacturers to recommend putting on "Auto-Ignition" or "Continuous Ignition" (or whatever a particular manufacturer calls it) for turbulence? And why? Is this an overly cautious practice recommended by some manufacturers? Or are some turbine engines actually prone to a flameout due to turbulence? What is the overall likelihood that turbulence can actually cause a turbine engine to flame out? How exactly would turbulence cause the fire to go out? I started wondering about this because I remember reading somewhere that the King Air 300 series recommends Auto-Ignition ON (i.e. "armed") in turbulence; but the King Air 200's do not mention Auto-Ignition Armed for turbulence ....... and I was wondering why the discrepancy. Which got me to wondering about it for other turbine engines and aircraft........
