The flight

What the tracklog shows, and which crossings scored.

Start time taken: gate 4 of 9 — the last start gate at or before the crossing. The speed-section clock runs from the gate, not from the crossing (FAI S7F §8.3.1).15:15:00

Track data cleaning

150 of 3528 GPS fixes (4.3%) carried an implausible altitude and were repaired before analysis — flagged by vertical-speed limits (no barometric channel to cross-check). Positions and times are never altered. How data cleaning works
