Citation Sovereign vs Citation X: how the two fleets are really flown
On three of the four chapters' lead measures, the gap inside each fleet is bigger than the gap between the Citation Sovereign and the Citation X. The clearest difference is short runways: the middle Citation Sovereign at 3%, the middle Citation X at 27%, with no overlap between their middle halves.

Fatigue
On hours per landing, the gap between the types is smaller than the spread inside either fleet: the middle Citation X at 1.7 : 1, the middle Citation Sovereign at 1.4 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Citation Sovereign vs Citation X: 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 Sovereign vs Citation X: questions
Which is flown more, the Citation Sovereign or the Citation X?
The Citation X, by about 82 estimated hours a year: the middle Citation X flew ≈195 h a year, the middle Citation Sovereign ≈113 h. That is a fleet median: the middle half of Citation Xs logged 112–503 h and of Citation Sovereigns 71–178 h, so one aircraft can sit far from its type. In flights, the medians are 7 a month for the Citation Sovereign and 11 for the Citation X.
Which lands more often for its hours, the Citation Sovereign or the Citation X?
The Citation Sovereign: 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 39% of the middle Citation Sovereign's legs and 29% of the middle Citation X's.
Which flies longer trips, the Citation Sovereign or the Citation X?
The Citation X, by 196 nm on the median leg: 607 nm for the middle aircraft, against 411 nm for the Citation Sovereign. 40% of Citation Sovereign legs and 31% of Citation X legs were under 300 nm, a gap of 9 percentage points; 19% and 35% were over 900 nm.
Which spends more nights by the sea, the Citation Sovereign or the Citation X?
The Citation X, by 3 percentage points: its middle aircraft spends 3% of its nights within 2 km of the coast, the middle Citation Sovereign 0%. 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 Sovereign or the Citation X?
The manufacturers quote 3,200 nm for the Citation Sovereign and 3,460 nm (Citation X+) for the Citation X. Those are book figures at stated conditions; how far the fleets actually fly is in the trip-length mix above.
