Working through some final details here:
The GEA24 and the GDU displays have "Aircraft Power #2" inputs.
Section 2.1.1.18 in the G3X Touch Installation Manual mentions the use of third party backup power systems, or integration of a backup battery into the aircraft electrical system.
I want to make sure that the system is adequately powered through transient voltage sags at engine start to ensure reliable oil pressure indication.
My current thinking is to use a small backup battery (alarm system gel cell or similar) on Aircraft Power #2 on the GEA and GDU, wired to the aircraft's main bus through a diode so that it can accept charge but can't power anything else.
Is that reasonable? Short of a full dual-bus architecture, how else have folks been working through this?
