What the profile screens for
A recorded airborne-collision-avoidance resolution advisory occurs outside the terminal approach segment.
Why it matters
An RA is a direct collision-avoidance cue and supports analysis of geometry, response, separation, and airspace context.
Build the event around relationships—not one number.
Define the operating context
Identify the climb / cruise / descent state, aircraft configuration, location, and any required external data before applying logic.
Screen the signal relationship
Use validated combinations of TCAS RA, vertical speed, pressure altitude; 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 TCAS RA, vertical speed, pressure altitude valid, correctly decoded, time-aligned, and sampled well enough for this event?
- Q2
What changed immediately before, during, and after the tcas resolution advisory in cruise 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?
