A remote pilot completes a flight with no incidents and packs up without reviewing the flight log or aircraft condition. On the next flight, the same aircraft displays an unexpected compass error that was present at the end of the prior flight. This scenario illustrates a failure at which stage of operations?
Why →
Post-flight evaluation is the Evaluate step in the DECIDE model and a standard part of any professional operation. Reviewing the aircraft's condition, flight logs, and any anomalies after each flight catches issues before they become problems on the next one. A compass error logged at the end of one flight that goes unreviewed becomes an undetected defect on the next flight. Post-flight evaluation is as important as the preflight inspection.The trap →
Choice A is partially right, a thorough preflight on the second flight might have caught the error, but the root failure was not doing a post-flight review after the first. Choice C is incorrect because the error appeared at the end of the first flight, not during decision-making mid-flight.SOURCE → PHAK Chapter 2, DECIDE Model; 14 CFR § 107.49CHECKED APR 22ACS V.C.K1MED
