What the profile screens for
Turn entry or completion occurs with high groundspeed, lateral acceleration, or steering demand for the geometry.
Why it matters
High turn energy can reduce directional margin and increase tyre, gear, passenger, and taxiway-excursion exposure.
Build the event around relationships—not one number.
Define the operating context
Identify the taxi state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of groundspeed, lateral acceleration, steering angle; 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 groundspeed, lateral acceleration, steering angle valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the high-speed taxi turn 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?
