Propeller pitch is automatically varied in flight by governor maintaining constant RPM.
Electrical system: What kind of battery and alternator volt system?
Powered by a 24V direct current, 11 Amp-hour, Lead-acid battery
and a 70amp 28V Alternator
How does electrical system works?
Battery ON ->The BAT RELAY Closes, and Main Battery sends current to BATT BUS then to Essential Bus sends current to Main/Ess Tie rely to main Bus (which powers starter.)
Engine running: Alternator ON provides current Volt Reg. thru Alternator to MAIN BUS. then to main/ess Tie relay to Essential bus to charge MAIN Batt)
Avions master ON 1) sends current to Main BUS to power Avionic Bus and 2) Essential bus provides power to Essential Avionic bus.
