Falcon 7X vs Falcon 900: how the two fleets are really flown
On all four chapters' lead measures, the gap inside each fleet is bigger than the gap between the Falcon 7X and the Falcon 900. On flights a month, the middle half of Falcon 7Xs runs 5–9 and of Falcon 900s 4–8; the medians are 7 and 5.

Fatigue
On hours per landing, the gap between the types is smaller than the spread inside either fleet: the middle Falcon 7X at 2.1 : 1, the middle Falcon 900 at 1.7 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Falcon 7X vs Falcon 900: on paper
Certified figures come from each type certificate data sheet, the rest from the manufacturer. Each figure names its source; a range covers the variants one page tracks together; a dash means we don’t have a source for that figure yet. We don’t have a manufacturer source for the Falcon 900 yet, so its manufacturer rows show a dash.

Falcon 7X vs Falcon 900: questions
Which is flown more, the Falcon 7X or the Falcon 900?
The Falcon 7X, by about 56 estimated hours a year: the middle Falcon 7X flew ≈173 h a year, the middle Falcon 900 ≈117 h. That is a fleet median: the middle half of Falcon 7Xs logged 138–233 h and of Falcon 900s 77–163 h, so one aircraft can sit far from its type. In flights, the medians are 7 a month for the Falcon 7X and 5 for the Falcon 900.
Which lands more often for its hours, the Falcon 7X or the Falcon 900?
The Falcon 900: its middle aircraft flies 1.7 hours per landing, against 2.1 for the Falcon 7X, 0.4 hours fewer per landing. More landings per hour means more pressurization cycles for the same time in the air. Short hops, legs under 300 nm, make up 28% of the middle Falcon 7X's legs and 32% of the middle Falcon 900's.
Which flies longer trips, the Falcon 7X or the Falcon 900?
The Falcon 7X, by 80 nm on the median leg: 614 nm for the middle aircraft, against 534 nm for the Falcon 900. 31% of Falcon 7X legs and 35% of Falcon 900 legs were under 300 nm, a gap of 4 percentage points; 36% and 27% were over 900 nm.
Which spends more nights by the sea, the Falcon 7X or the Falcon 900?
About the same: the middle aircraft of both types spends 1% of its nights within 2 km of the coast. Salt air is one of the corrosion inputs a TailCheck report grades for one aircraft against its own type.

Method: Falcon 7Xs and Falcon 900s with most departures in North America, ADS-B tracking. Flight measures cover 1 Aug 2025 – 31 Jul 2026; each figure is the median of its own fleet, with the middle half (25th–75th percentile). Estimated hours from time in the air. We assume the longest runway at each field, so short-runway figures are conservative. Specifications from type certificate data sheets and the manufacturers, each cited. About our data
