What the profile screens for
A stall warning, stick-shaker, or equivalent low-speed alert occurs during approach or landing.
Why it matters
Low-height stall warning indicates reduced lift margin and may precede loss of control, hard contact, or undershoot.
Build the event around relationships—not one number.
Define the operating context
Identify the approach / landing state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of stall warning, angle of attack, 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 ↗% / 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 ↗Questions before conclusions
- Q1
Are stall warning, angle of attack, airspeed valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the stall warning on approach 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.
Windshear and Microburst
Recognize rapid changes in wind vector and the resulting airspeed, path, thrust, and vertical-energy effects close to the ground.
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 ↗Flight OperationsControlled Flight Into Terrain
Understand how a controllable aircraft can be flown into terrain or an obstacle through path, altitude, navigation, monitoring, or situational-awareness breakdowns.
