That said, I'm not sure I see how an alternator failure would cause a need for an urgent landing, or parachute deployment . The aircraft will be certified for 30 minutes flying on the battery, and thereafter the engine will still run, even with a flat battery.
And on a Cirrus you still have the equipment powered by the No 2 Alternator which powers the Essential Bus.
