ALT 1 Failure (Alt 1 Light Steady)
Steady illumination indicates failure of alternator 1. Attempt to restore
alternator. If alternator cannot be restored, it will be necessary to divert
the flight to land within one hour.
Loads on Main Buses, Non-essential Buses, and Air-conditioning
Buses must be reduced and available equipment on these buses
managed as necessary for flight conditions. Equipment essential for
continued safe flight and landing will be powered by Alternator 2 and
Battery 2 through the Essential Buses. However, depending upon
flight conditions, additional equipment is required.
For 14 CFR 135 Operations, the load shedding and equipment
management in the following procedure will provide at least one-hour
operating time on aircraft with a fully charged, 13.6 amp-hour battery
(available from Cirrus Design Spare Parts Sales) in good condition for
equipment required for emergency operation under 14 CFR 135.163(f)
and meets the requirements of that paragraph.
