What the profile screens for
A go-around or rejected-landing sequence begins after one or more recorded ground contacts.
Why it matters
Post-touchdown go-around can involve inhibited modes, changing ground logic, lift-dump systems, configuration, and limited height.
Build the event around relationships—not one number.
Define the operating context
Identify the landing / go around state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of weight-on-wheels, go-around mode, 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.
Pitch 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 ↗deg or discreteGround spoiler position
Position or deployment state of panels used to reduce lift and increase wheel loading after touchdown.
Open parameter guide ↗discrete or %Thrust reverser status
Command and/or physical deployment state for reverse thrust, depending on recorded signal availability.
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 ↗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 weight-on-wheels, go-around mode, thrust valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the go-around after touchdown 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.
Stabilized approach criteria
The operator-defined gates and conditions used to judge whether path, speed, configuration, thrust, and crew readiness support safe continuation.
Open topic profile ↗SAT-017 · Approach & landingLanding flare
Transition from approach descent to touchdown, including pitch, thrust, sink, visual cues, wind, aircraft response, and runway remaining.
Open topic profile ↗SAT-018 · Approach & landingBounced landing recovery
Recognition and management of rebound after initial runway contact, including the decision to continue, reject the landing, or go around.
Open topic profile ↗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.
