What the profile screens for
Go-around initiation occurs at low height or after a prolonged unstable condition according to validated programme logic.
Why it matters
Late initiation compresses time for thrust, configuration, pitch, flight-path, traffic, and terrain response.
Build the event around relationships—not one number.
Define the operating context
Identify the approach / go around state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of go-around mode, radio altitude, thrust; 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 ↗degPitch attitude
Aircraft body attitude above or below the local horizontal reference.
Open parameter guide ↗% / ratio / aircraft-specificEngine thrust
One or more recorded measures of commanded or produced propulsion; the correct signal depends on engine and aircraft type.
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 go-around mode, radio altitude, thrust valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the late 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?
Safety topics that broaden the event review.
Go-Around Decision and Execution
Treat the go-around as both a normal safety decision and a manoeuvre whose mode, thrust, configuration, path, and workload must be monitored.
Open topic brief ↗Aircraft SystemsFlight-Deck Automation
Use mode awareness, active monitoring, and aircraft-response verification to keep automation aligned with crew intent.
Open topic brief ↗Aircraft SystemsEngine Failure and Thrust Loss
Separate commanded thrust, actual engine response, system effects, and crew management across partial, asymmetric, and complete thrust-loss events.
