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.

01 · Gate

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.

02 · Detect

Screen the signal relationship

Use validated combinations of door warning, door position, cabin altitude; avoid treating one isolated value as the whole event.

03 · Validate

Confirm it is a genuine event

Check polarity, units, source, recording rate, dropouts, air/ground logic, persistence, and false-positive mechanisms.

04 · Contextualise

Connect data to the safety question

Review procedures, reports, weather, airport and traffic context, exposure, recurrence, and the strength of the related barriers.

Questions before conclusions

  1. Q1

    Are door warning, door position, cabin altitude valid, correctly decoded, time-aligned, and sampled well enough for this event?

  2. Q2

    What changed immediately before, during, and after the door warning in flight indication?

  3. Q3

    How do aircraft configuration, weather, airport geometry, automation state, and crew reports change the interpretation?

  4. Q4

    Which current flight manual, SOP, maintenance, or operator event definition controls the final conclusion?
