What the profile screens for
Bank angle exceeds a validated low-height go-around or missed-approach monitoring condition.
Why it matters
High bank can reduce climb performance and terrain margin and may reflect path, traffic, wind, or control-response demands.
Build the event around relationships—not one number.
Define the operating context
Identify the go around state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of roll angle, radio altitude, 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.
Radio altitude
Height derived from radio altimetry, normally representing the distance from the aircraft to terrain directly below within the system's operating range.
Open parameter guide ↗ktCalibrated airspeed
Indicated airspeed corrected for instrument and position error, as provided by the aircraft data system.
Open parameter guide ↗degRoll angle
Aircraft bank attitude about the longitudinal axis.
Open parameter guide ↗discrete / modeAutopilot status
Engagement and mode states for automatic flight-control systems; useful analysis normally needs more than a single on/off bit.
Open parameter guide ↗Questions before conclusions
- Q1
Are roll angle, radio altitude, airspeed valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the excessive bank during go-around 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?
