 Another thing I'd like them to explain is how they determine whether the
pilot wants economy cruise at altitude or best power (to climb over an
aproaching mountain or weather).  The throttle is in the same position (wide
open) for both cases.  The only difference is mixture control.  If it is a
single lever power control, how the hell does the controller know what the
pilot wants?  I asked this question to the people at PowerSport (who also
use a pseudo FADEC system).  They couldn't give me an answer then but
promised to get it for me.  I'm still waiting.

Well, the throttle may be in the same position in a conventional aircraft setup
(separate throttle and mixture), but presumably in a FADEC system, the pilot puts
the lever at full power for climbing over the mountain, and some lesser position
for economy cruise (at altitude).  The lever is no longer a "throttle" per se, but
rather a "power demanded" indicator.  This assumes that the lever isn't attached
to anything other than an encoder for the FADEC.
