>>1089950Diesel engines are great unless you live somewhere that gets quite cold. I got my commercial multi in a DA42NG, sporting two Austro AE300 turbo-normalized diesel engines, pic related. Performance was great; the thing burned something 13 GPH total at 75%. GA aircraft that burn Jet-A aren't very common, but I have a feeling they'll become more popular.
>>1089954Well he isn't wrong, treehuggers didn't like the fact that lead was in the fuel so they tried to ban it. When it wasn't banned they decided to tax it heavily. It's more expensive than Jet-A in many places now, so I think it's gradually on the way out.
