Challenger 300/350 vs G280: 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 Challenger 300/350 and the G280. The clearest difference is salt air: the middle Challenger 300/350 at 4%, the middle G280 at 1%.

Fatigue
On hours per landing, the two fleets' medians match, at 1.6 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

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.

Challenger 300/350 vs G280: questions
Which is flown more, the Challenger 300/350 or the G280?
The Challenger 300/350, by about 23 estimated hours a year: the middle Challenger 300/350 flew ≈194 h a year, the middle G280 ≈171 h. That is a fleet median: the middle half of Challenger 300/350s logged 114–527 h and of G280s 113–248 h, so one aircraft can sit far from its type. In flights, the medians are 10 a month for the Challenger 300/350 and 9 for the G280.
Which lands more often for its hours, the Challenger 300/350 or the G280?
About the same: the middle aircraft of both types flies 1.6 hours 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 34% of the middle G280's.
Which flies longer trips, the Challenger 300/350 or the G280?
The G280, by 8 nm on the median leg: 489 nm for the middle aircraft, against 481 nm for the Challenger 300/350. Both fleets flew 36% of their legs under 300 nm; 24% of Challenger 300/350 legs and 22% of G280 legs were over 900 nm.
Which spends more nights by the sea, the Challenger 300/350 or the G280?
The Challenger 300/350, by 3 percentage points: its middle aircraft spends 4% of its nights within 2 km of the coast, the middle G280 1%. 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 G280?
The manufacturers quote 3,065–3,200 nm for the Challenger 300/350 and 3,600 nm for the G280. Those are book figures at stated conditions; how far the fleets actually fly is in the trip-length mix above.
Does this comparison include the Challenger 350?
Yes. The tracking data doesn't tell the Challenger 300 and Challenger 350 apart, so the Challenger 300/350 figures here cover all of them. The specs table names a figure’s variants where the sources separate them.
