What the profile screens for
Generator, bus, battery, voltage, frequency, or warning data indicate loss or degradation of electrical supply.
Why it matters
Electrical faults can affect instruments, automation, navigation, communication, lighting, fire protection, and redundancy.
Build the event around relationships—not one number.
Define the operating context
Identify the taxi / takeoff / climb / cruise / descent / approach / landing state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of generator status, bus status, voltage; avoid treating one isolated value as the whole event.
Confirm it is a genuine event
Check polarity, units, source, recording rate, dropouts, air/ground logic, persistence, and false-positive mechanisms.
Connect data to the safety question
Review procedures, reports, weather, airport and traffic context, exposure, recurrence, and the strength of the related barriers.
Recorded signals that may help explain the event.
Engine thrust
One or more recorded measures of commanded or produced propulsion; the correct signal depends on engine and aircraft type.
Open parameter guide ↗discrete / modeAutopilot status
Engagement and mode states for automatic flight-control systems; useful analysis normally needs more than a single on/off bit.
Open parameter guide ↗Questions before conclusions
- Q1
Are generator status, bus status, voltage valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the electrical-system warning or degradation indication?
- Q3
How do aircraft configuration, weather, airport geometry, automation state, and crew reports change the interpretation?
- Q4
Which current flight manual, SOP, maintenance, or operator event definition controls the final conclusion?
Safety topics that broaden the event review.
Electrical system failure
Generator, bus, battery, wiring, distribution, or power-quality failure and the resulting loss or degradation of aircraft capability.
