Scenario & Physics Summary
Immediate electrical load shedding protocol when the ammeter shows negative charge or the ALT WARN light illuminates during night flight.

Aerodynamic & Operational Physics
The battery alone provides only 30-45 minutes of reserve power once the alternator drops offline.
Night VFR requires avionics, nav lights, landing light, pitot heat, and instrument backlights—drawing over 20-30 Amps continuously.
Load shed non-essential bus equipment (landing lights until final, secondary radios, interior cabin lighting) immediately to preserve battery for flaps, radio, and transponder.
CASA & FAA Exam Gotcha Alert
CASA / FAA Exam Trap: Do not re-engage a tripped alternator circuit breaker more than once if it pops immediately, as it indicates a primary short circuit and fire hazard.
Frequently Asked Questions & Exam Explanations
What is the first action when an alternator fails at night?
Check voltage/ammeter, cycle ALT switch once. If it remains offline, immediately load-shed non-essential electrical equipment to preserve battery power for landing.
