Brief Description: Electrical system design
|
|
(22.5 hrs.) This entry represents the past two weeks of work on designing the electrical system and the instrument panel. I've spent a lot of time thinking through each electrical component, how it will be powered and from which bus, various failure modes, and panel ergonomics. I distilled my systems designs into a series of detailed schematics, drawn with a CAD program called SmartDraw 7 (which I highly recommend!), and I used ePanelBuilder.com to tweak the main panel design. EpanelBuilder does not yet include the new high-resolution GRT screens (which are taller than the old ones), nor does it allow me to draw rectangular annunciator lights, or toggle switches that move left/right instead of up/down. Otherwise the panel is pretty close to accurate.
My Main Switch Panel, on the right side of the cockpit, came out pretty nice. I have to consider whether it's a good idea having a fresh air vent directly above it. I don't want moisture blowing out of the vent onto the switches. I might have to move the vent someplace else -- maybe up one hole, where the compass is shown.

My latest instrument panel plan, minus the labels. The annunciator lights should be rectangular.
