Nice to see this finally reaching a visibility status. Let's see how long it really takes to get it on the market ... anybody remembers how long the Cessna JT-A is reported as "almost ready"? ...

Jet A1 does offer advantages, but - there is no free lunch!
Yes, in certain parts of the world it is mandatory to go this fuel line, as a separate fuel distribution for GA does not make sense right now. Yes, flying Jet or "Diesel" has it's beauty - less fuel burn, cheaper fuel, more range.
But No, it also has disadvantages. Turbo engines quit when turbo quits, when electronic control unit quits engine stopps, unknown influence on environment (one point which WILL come, as common eco terrorists tend to be unreachable by intellect and facts, but jump onto each possible pin point for media coverage).

One open question from us Fraggles croud to the Forum Marjory the Trash Heap: does SMA offer TBO for the 4-cyl. and 6-cyl., or is it TBR?
In my view, that was one of the major drawbacks with Diesel-engine conversion before.
