614 tracked tails, 73% in service. United States carries the largest registry share at 64%. The 2016–2020 delivery cohort is the largest at 27% of the fleet. 556 tails clear the tracking floor. Median annual utilisation sits at 145 hrs (mean 182 hrs) — the mean running well above the median points to a small high-utilisation tail pulling the average up. The middle 80% of the fleet flies between 34 and 363 hrs/yr.

Behavioural signals inferred from ADS-B activity and a curated OEM/MRO airport reference list — not a listing, maintenance, or grounding database. Every finding below is SOFT: a pattern consistent with, not proof of, the event named.

No simultaneous fleet-wide dark period crossed threshold — month-to-month dark share stays within 29% ± 15pp of its trailing baseline.
MRO-visit inference matches flight destinations against a curated list of known OEM completion centers and independent MRO hubs — coverage is editorial, not exhaustive. Attrition counts tails silent 120+ days per the same dormancy classifier Radar uses; a true multi-period attrition trend needs a snapshot history this build does not yet keep.
Physical base derived from each tail’s own most-frequent airport across its tracked flights — not registration jurisdiction.

THE PROFESSIONAL READ
614 tracked tails, 73% in service. United States carries the largest registry share at 64%. The 2016–2020 delivery cohort is the largest at 27% of the fleet. 556 tails clear the tracking floor. Median annual utilisation sits at 145 hrs (mean 182 hrs) — the mean running well above the median points to a small high-utilisation tail pulling the average up. The middle 80% of the fleet flies between 34 and 363 hrs/yr. 12 tails show a behavioural pattern consistent with pre-sale prep — see §03 SIGNALS.
Evidence discipline
1 active tails (0%) fall below the 4-movement tracking floor this window — typically data-sparse operating regions or recent entrants to the fleet — and are excluded from utilisation and signal figures, not silently averaged in.
How this is built: every figure derives from ADS-B activity for tracked G650 tails plus published aircraft-registry metadata — no MRO, listing, or AD/grounding database exists behind this product. §01 census reads directly from the track (FROM TRACK); §02 utilization is calculated from time airborne (MODELED); §03 signals are inferred behavioural patterns only (SOFT), matched against a curated, non-exhaustive OEM/MRO airport list; §04 geography derives physical base from each tail's own most-frequent airport, not registration jurisdiction; §05 benchmarks against the most-active comparable types this window. 445 of 446 active aircraft show ADS-B coverage sufficient for utilisation inference (≥4 tracked movements); 1 excluded for thin in-window coverage. Pricing, comps, and valuation sit outside this tool.
