What the profile screens for
A passenger, service, cargo, or access-door warning or disagree state is recorded while airborne.
Why it matters
Door indications can involve pressurisation, structural, cargo, checklist, return, and landing considerations and require signal validation.
Build the event around relationships—not one number.
Define the operating context
Identify the takeoff / initial climb / climb / cruise / descent / approach state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of door warning, door position, cabin altitude; 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.
Questions before conclusions
- Q1
Are door warning, door position, cabin altitude valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the door warning in flight 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.
Pressurization events
Abnormal cabin altitude, rate, differential pressure, controller, valve, leakage, or warning behavior during flight.
