What the profile screens for

Pitch attitude rises above an aircraft- and phase-specific monitoring band shortly after liftoff.

Why it matters

High pitch can reduce speed margin and may signal over-rotation, windshear response, guidance mismatch, or manual-control difficulty.

Build the event around relationships—not one number.

01 · Gate

Define the operating context

Identify the initial climb state, aircraft configuration, location, and any required external data before applying logic.

02 · Detect

Screen the signal relationship

Use validated combinations of pitch attitude, pitch rate, airspeed; 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.

Recorded signals that may help explain the event.

Questions before conclusions

  1. Q1

    Are pitch attitude, pitch rate, airspeed valid, correctly decoded, time-aligned, and sampled well enough for this event?

  2. Q2

    What changed immediately before, during, and after the excessive pitch in initial climb 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?
