What the profile screens for
Pitch-up begins earlier than the validated rotation reference or operator event definition.
Why it matters
Early rotation can reduce acceleration margin and increase tail-clearance, stall-margin, or performance exposure.
Build the event around relationships—not one number.
Define the operating context
Identify the takeoff state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of pitch attitude, pitch rate, calibrated airspeed; 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.
Calibrated airspeed
Indicated airspeed corrected for instrument and position error, as provided by the aircraft data system.
Open parameter guide ↗degPitch attitude
Aircraft body attitude above or below the local horizontal reference.
Open parameter guide ↗discreteLanding gear status
Command, position, lock, and ground-sensing states associated with the landing gear; these are separate signals with different meanings.
Open parameter guide ↗Questions before conclusions
- Q1
Are pitch attitude, pitch rate, calibrated airspeed valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the early takeoff rotation 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?
