Citation X vs 800XP/850XP/900XP/750: 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 Citation X and the 800XP/850XP/900XP/750. On flights a month, the middle half of Citation Xs runs 6–22 and of 800XP/850XP/900XP/750s 5–15; the medians are 11 and 10.

Citation X vs 800XP/850XP/900XP/750: 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 800XP/850XP/900XP/750 yet, so its manufacturer rows show a dash.

Citation X vs 800XP/850XP/900XP/750: questions
Which is flown more, the Citation X or the 800XP/850XP/900XP/750?
The Citation X, by about 38 estimated hours a year: the middle Citation X flew ≈195 h a year, the middle 800XP/850XP/900XP/750 ≈157 h. That is a fleet median: the middle half of Citation Xs logged 112–503 h and of 800XP/850XP/900XP/750s 95–262 h, so one aircraft can sit far from its type. In flights, the medians are 11 a month for the Citation X and 10 for the 800XP/850XP/900XP/750.
Which lands more often for its hours, the Citation X or the 800XP/850XP/900XP/750?
The 800XP/850XP/900XP/750: its middle aircraft flies 1.4 hours per landing, against 1.7 for the Citation X, 0.3 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 29% of the middle Citation X's legs and 40% of the middle 800XP/850XP/900XP/750's.
Which flies longer trips, the Citation X or the 800XP/850XP/900XP/750?
The Citation X, by 206 nm on the median leg: 607 nm for the middle aircraft, against 401 nm for the 800XP/850XP/900XP/750. 31% of Citation X legs and 43% of 800XP/850XP/900XP/750 legs were under 300 nm, a gap of 12 percentage points; 35% and 18% were over 900 nm.
Which spends more nights by the sea, the Citation X or the 800XP/850XP/900XP/750?
The Citation X, by 2 percentage points: its middle aircraft spends 3% of its nights within 2 km of the coast, the middle 800XP/850XP/900XP/750 1%. Salt air is one of the corrosion inputs a TailCheck report grades for one aircraft against its own type.
