What the profile screens for
Anti-ice or de-ice system state differs from the validated environmental, phase, or procedure context.
Why it matters
Incorrect system use can affect icing protection, engine or wing performance, bleed demand, fuel use, and procedure compliance.
Build the event around relationships—not one number.
Define the operating context
Identify the taxi / takeoff / climb / cruise / descent / approach state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of engine anti-ice, wing anti-ice, temperature; 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 engine anti-ice, wing anti-ice, temperature valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the anti-ice configuration mismatch 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?
