I was told by a DLR employee that he couldn't recall an aircraft that needed less paper mass than engine weight. For such an aircraft we're talking tenthousands of pages...At this end of the power range, I'm all with Autoreply. Especially with a new design. And I'm hearing noises about "killing the VLJ phenomenon", which suggests production is in somebody's mind. If you want to sell it Part23 certified, you're going to need to have the engine certified, too. And you have not seen paperwork, I'm told, until you try to certify an engine for aero use.
