Cool panel layout.  Great to have some interior design added to the great
shape of the Legacy.
You might consider that the Chelton system has built in warnings (visual and
aural) for the fuel qty, fuel pressure, oil pressure, oil temp, CHT's,
EGT's, TIT's, fuel flow, voltage,  manifold pressure, RPM, etc.  I don't see
any need for the duplication.  Certain annunciations should be color coded
as to their immediacy of concern.  For example, Canopy should be RED
(serious), whereas gear pump running might be yellow (as a warning) and gear
down - Green (normal/good).  These are just a few thoughts, and how I tried
to layout my annunciator panel.  One thing is certain - its not as cool as
what you're doing.

>>>Itšs organized into three basic categories represented by the rows:
Configuration, Engine, and Electrical.  The landing gear, flaps, and speed
brakes respond as a function of airspeed and power level (eg. going slow
should be in landing configuration, going fast you should be in cruise
configuration?).  Bus 1 and Bus 2 respond to bus voltage level. The far left
lights illuminate if anything in that category/row is out of spec.  Therešs
no vacuum pressure annunciator because wešre going all electric ­ the MTBF
(mean time between failures) of vacuum pumps is too low for me.<<<<
