This gives pilots a way to continuously monitor the electrical system during flight to catch problems before they become dangerous.\n\n**Alternative option:** Instead of separate ammeters, you can use one switchable ammeter that can alternate between the battery and generator lines, provided the switch can be set to monitor a generator line at all times during flight.\n\n**When you must comply:** Immediately (the directive uses the term \"forthwith\")."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-30-17-amdt-1-electrical-power-indicators-modification","history":"/api/acts/ad-pa-30-17-amdt-1-electrical-power-indicators-modification/history","analysis":"/api/acts/ad-pa-30-17-amdt-1-electrical-power-indicators-modification/analysis","conflicts":"/api/acts/ad-pa-30-17-amdt-1-electrical-power-indicators-modification/conflicts","importantCases":"/api/acts/ad-pa-30-17-amdt-1-electrical-power-indicators-modification/important-cases","documents":"/api/acts/ad-pa-30-17-amdt-1-electrical-power-indicators-modification/documents"}}
