Mooney M20 C-GXPD shows a lone 1,274-knot speed spike
The reports bracketing the spike were 169 and 140 knots. The aircraft was reported near Stockbridge, Michigan.
A single ground-speed report jumped to 1,274 knots between readings of 169 and 140 knots on July 23, 2026. The aircraft database lists C-GXPD as a Mooney M20, and the aircraft was reported near Stockbridge, Michigan. The reports on either side were each 15 seconds from the spike.
That abrupt jump and return could reflect a decoding or data error. All 10 surrounding reports recorded speeds between 137 and 169 knots. The isolated value does not establish the aircraft's performance, and these readings cannot establish what caused the error.
