Citation X vs G650: how the two fleets are really flown
On two of the four chapters' lead measures, the gap inside each fleet is bigger than the gap between the Citation X and the G650. The clearest difference is hours per landing: the middle Citation X at 1.7 : 1, the middle G650 at 2.5 : 1, with no overlap between their middle halves.

Fatigue
On hours per landing, the fleets part: the middle G650 at 2.5 : 1, the middle Citation X at 1.7 : 1, and their middle halves don't overlap.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Citation X vs G650: 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.

Citation X vs G650: questions
Which is flown more, the Citation X or the G650?
The G650, by about 4 estimated hours a year: the middle G650 flew ≈199 h a year, the middle Citation X ≈195 h. That is a fleet median: the middle half of G650s logged 139–271 h and of Citation Xs 112–503 h, so one aircraft can sit far from its type. In flights, the medians are 11 a month for the Citation X and 7 for the G650.
Which lands more often for its hours, the Citation X or the G650?
The Citation X: its middle aircraft flies 1.7 hours per landing, against 2.5 for the G650, 0.8 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 30% of the middle G650's.
Which flies longer trips, the Citation X or the G650?
The G650, by 47 nm on the median leg: 654 nm for the middle aircraft, against 607 nm for the Citation X. 31% of Citation X legs and 33% of G650 legs were under 300 nm, a gap of 2 percentage points; 35% and 39% were over 900 nm.
Which spends more nights by the sea, the Citation X or the G650?
About the same: the middle aircraft of both types spends 3% 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.
Which has the longer range on paper, the Citation X or the G650?
The manufacturers quote 3,460 nm (Citation X+) for the Citation X and 7,000–7,500 nm for the G650. Those are book figures at stated conditions; how far the fleets actually fly is in the trip-length mix above.
