En-Route
I am pretty sure 2 were fuel exhaustion and one was a carb ice issue.I was told by my instructor that engine outs happen more near an airport because you are changing things to the engine. An hour or 2 at cruise is the same conditions to the engine. Now you are changing air/fuel ratios, prop speeds and power settings when you land. I dont know if thats really true, but it stuck with me.
