ISSUE DESCRIPTION
Description of the issue:After updating to SU6 Beta 1.8.5.0 (July 6, 2026), the default Cessna 172 Steam Gauge has an electrical initialization issue.
When starting from Cold & Dark using the normal checklist, the following instruments remain unpowered:
- KAP140 Autopilot
- Transponder
- Digital Clock
However:
- The same aircraft works correctly when starting with Ready to Fly.
- Pressing CTRL+E immediately powers all affected instruments without any further action.
This suggests that the manual startup sequence is not correctly initializing one or more avionics/electrical buses.
