No tail is promoted here by default. Select one — below, on a ladder, in the table — to read the set against it.
This board runs on 5 real Falcon 7X tails, tracked over 1 Sep 2025 – 29 Aug 2026.
Five tails, tracked the same way over the same window. Select any one below to see where it leads and where it trails against the other four — nothing here changes which tails are compared, only which one the narrative is read against.
TailCheck measures how an aircraft has been operated. It does not infer its physical condition. Each metric is one axis: the percentile each tail occupies within its own type, so aircraft of different sizes can sit on the same line. The spotlight tail and the two extremes are labelled; the rest are in the table below.
The axis is stretched at both ends so differences in the top decile, where most of this set sits, don’t get flattened out.
Ticks mark 0, the type median and 100. The shaded bar shows how far the spotlight sits from the median on that axis.
Each figure is the longest period with no tracked movement, sized against that tail’s own rhythm. Listed answer-first.
12 of 12 months tracked across every tail in this set — no window without reception.
