FAR 23.1165 : Engine ignition systems.
(a)
Eachbatteryignition system mustbe supplementedbyagenerator thatis automati-cally available as an alternate source of electrical energy to allow continued engine operation if any battery becomes depleted.
(b)
The capacity of batteries and generators must be large enough to meet the simul-taneous demands of the engine ignition system and the greatest demands of any electrical system components that draw from the same source.
(c)
The design of the engine ignition system must account for–
(1)
The condition of an inoperative generator;
(2)
The condition of a completely depleted battery with the generator running at its normal operating speed; and
(3)
The condition of a completely depleted battery with the generator operating at idling speed, if there is only one battery.
(d)
There must be means to warn appropriate crewmembers if malfunctioning of any partof the electrical systemis causing the continuousdischarge of anybattery used for engine ignition.
