OK... bracing for the flaming but i am a VERY new Pilot... yes i have my ticket and passed Air tech which may make this worse..
Rubbish! Since when does the master switch shut down the engine in a Warrior, albeit a 235 Dakota?....and. how can a flat battery be the sole cause of a fuel driven piston engine failing?
If the alternator goes it does not charge the battery, in this case the battery will run down eventually. you'll loose things like radios, lights, flaps if electric. but the engine will still run ... right? The batt holds the initial charge to start the engine and as a short term backup should the alt fail... right?
Also the PA38's and 28's i have flown have had both split and 'solid' master switches. any idea why?
