Citation Longitude vs Citation X: 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 Longitude and the Citation X. The clearest difference is salt air: the middle Citation Longitude at 9%, the middle Citation X at 3%.

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 Longitude at 1.6 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Citation Longitude 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 Longitude vs Citation X: questions
Which is flown more, the Citation Longitude or the Citation X?
The Citation Longitude, by about 472 estimated hours a year: the middle Citation Longitude flew ≈667 h a year, the middle Citation X ≈195 h. That is a fleet median: the middle half of Citation Longitudes logged 168–752 h and of Citation Xs 112–503 h, so one aircraft can sit far from its type. In flights, the medians are 35 a month for the Citation Longitude and 11 for the Citation X.
Which lands more often for its hours, the Citation Longitude or the Citation X?
The Citation Longitude: its middle aircraft flies 1.6 hours per landing, against 1.7 for the Citation X, 0.1 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 Longitude's legs and 29% of the middle Citation X's.
Which flies longer trips, the Citation Longitude or the Citation X?
The Citation X, by 177 nm on the median leg: 607 nm for the middle aircraft, against 430 nm for the Citation Longitude. 39% of Citation Longitude legs and 31% of Citation X legs were under 300 nm, a gap of 8 percentage points; 24% and 35% were over 900 nm.
Which spends more nights by the sea, the Citation Longitude or the Citation X?
The Citation Longitude, by 6 percentage points: its middle aircraft spends 9% of its nights within 2 km of the coast, the middle Citation X 3%. 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 Longitude or the Citation X?
The manufacturers quote 3,500 nm for the Citation Longitude 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.
