Soon Jacksonville Center calls with a new routing that takes us east of Atlanta before heading to Louisville. This gets me to thinking. I see the swirl of Ernesto and to the west another fling of rain arcing through Ohio. There's a gap on the Nexrad of over a hundred miles. Just because there's no significant precip, does that mean there's no ice? No turbulence? Another call from Jax cements my decision. They want us to go further east, over Alma, Georgia, before heading west. I dial up Spartanburg, South Carolina, weather on the Avidyne, see that it is acceptable and change our destination. We can get fuel there and climb out to higher altitudes before reaching the worst of the weather. I've been to Spartanburg before. The people were nice and jet A price reasonable. The ILS to 5 at Spartanburg airport is easy, the turn is quick and we're soon climbing out towards Beckley (BKW), about where the weather starts. I note that the right engine is running fine, a condition that pleases me. I can deal with mechanical or weather challenges, but I'm disinclined to the combination of the two. I don't know a lot about hot sections except for their pricey reputation. I have known owners who have ignored overhaul or hot section recommendations, but I've concluded that I'm a chicken when it comes to tempting the gods with inattention to engine manufacturer suggestions.
