HEX_CASE_SPOOF · N5220L
Aircraft transponder broadcasting non-standard lowercase hex variant 'a692bf' (normalized to uppercase 'A692BF')
Each entry was flagged by the statistical model after the baseline period. Each row is cryptographically hashed, timestamped, and chained. We didn't pick them. The deviation from normal did.
Every row below is a flight detected at or under 500 ft while airborne — the altitude band where a helicopter has no time to autorotate to a survivable landing if the engine fails. Reference: FAA AC 90-87C (Helicopter Height-Velocity Diagram). Altitude here is reported barometric; negative and zero-altitude transponder anomalies are excluded.

Fixed-wing at 6.2kts. Stall 33kts, Vref min 55kts. Sustained below 1.2x stall is not an IFR approach. It is a stakeout with wings.
Fixed-wing (R44 II) at 5.0kts / 1900ft. Stall 33kts. This is parking, not flight.
44.5kts at 850ft. Below Vref 55kts. Sustained low-altitude loiter.
51.4kts at 400ft. Below Vref 55kts. Sustained low-altitude loiter.
Fixed-wing (76) at 4.1kts / 2800ft. Stall 33kts. This is parking, not flight.
Fixed-wing at 17.0kts. Stall 33kts, Vref min 55kts. Sustained below 1.2x stall is not an IFR approach. It is a stakeout with wings.
