Standby-power question
Ask which selected loads should retain power, what source feeds them, and whether conversion is required. Do not assume “standby” means the whole aircraft stays powered.
Use this as a refresher
Place the idea inside the full system chain: source/input → control → physical response → sensing/indication → consumer/result. If the quick note seems to conflict with the aircraft in front of you, stop and confirm configuration, effectivity and current approved data.
Maintenance boundary: this is a study reminder, not a task instruction.
