Challenger 300/350 vs Citation Sovereign: 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 Challenger 300/350 and the Citation Sovereign. The clearest difference is short runways: the middle Challenger 300/350 at 20%, the middle Citation Sovereign at 3%, 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 Challenger 300/350 at 1.6 : 1, the middle Citation Sovereign at 1.4 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Challenger 300/350 vs Citation Sovereign: questions
Which is flown more, the Challenger 300/350 or the Citation Sovereign?
The Challenger 300/350, by about 81 estimated hours a year: the middle Challenger 300/350 flew ≈194 h a year, the middle Citation Sovereign ≈113 h. That is a fleet median: the middle half of Challenger 300/350s logged 114–527 h and of Citation Sovereigns 71–178 h, so one aircraft can sit far from its type. In flights, the medians are 10 a month for the Challenger 300/350 and 7 for the Citation Sovereign.
Which lands more often for its hours, the Challenger 300/350 or the Citation Sovereign?
The Citation Sovereign: its middle aircraft flies 1.4 hours per landing, against 1.6 for the Challenger 300/350, 0.2 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 35% of the middle Challenger 300/350's legs and 39% of the middle Citation Sovereign's.
Which flies longer trips, the Challenger 300/350 or the Citation Sovereign?
The Challenger 300/350, by 70 nm on the median leg: 481 nm for the middle aircraft, against 411 nm for the Citation Sovereign. 36% of Challenger 300/350 legs and 40% of Citation Sovereign legs were under 300 nm, a gap of 4 percentage points; 24% and 19% were over 900 nm.
Which spends more nights by the sea, the Challenger 300/350 or the Citation Sovereign?
The Challenger 300/350, by 4 percentage points: its middle aircraft spends 4% 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 Challenger 300/350 or the Citation Sovereign?
The manufacturers quote 3,065–3,200 nm for the Challenger 300/350 and 3,200 nm for the Citation Sovereign. Those are book figures at stated conditions; how far the fleets actually fly is in the trip-length mix above.
