Challenger 600 series vs Legacy 600/650: how the two fleets are really flown
On all three chapters' lead measures, the gap inside each fleet is bigger than the gap between the Challenger 600 series and the Legacy 600/650. On flights a month, the middle half of Challenger 600 series aircraft runs 5–14 and of Legacy 600/650s 8–14; the medians are 8 and 10.

Fatigue
On hours per landing, the gap between the types is smaller than the spread inside either fleet: the middle Legacy 600/650 at 1.8 : 1, the middle Challenger 600 series at 1.7 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Corrosion
Salt air, damp hours and freeze–thaw can’t be compared here: only 25 of the 46 Legacy 600/650s were placed on enough nights in the twelve months, and a comparison needs at least 30.
What the air around the fleet does overnight: salt, damp and freeze–thaw.
Engines and brakes
On hot, high takeoffs, the gap between the types is smaller than the spread inside either fleet: the middle Legacy 600/650 at 6%, the middle Challenger 600 series at 5%.
What departures ask of engines, brakes and tires: heat and height, and runway length.

Challenger 600 series vs Legacy 600/650: 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. We don’t have a manufacturer source for the Legacy 600/650 yet, so its manufacturer rows show a dash.

Challenger 600 series vs Legacy 600/650: questions
Which is flown more, the Challenger 600 series or the Legacy 600/650?
The Legacy 600/650, by about 41 estimated hours a year: the middle Legacy 600/650 flew ≈221 h a year, the middle Challenger 600 series ≈180 h. That is a fleet median: the middle half of Legacy 600/650s logged 169–282 h and of Challenger 600 series aircraft 118–301 h, so one aircraft can sit far from its type. In flights, the medians are 8 a month for the Challenger 600 series and 10 for the Legacy 600/650.
Which lands more often for its hours, the Challenger 600 series or the Legacy 600/650?
The Challenger 600 series: its middle aircraft flies 1.7 hours per landing, against 1.8 for the Legacy 600/650, 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 34% of the middle Challenger 600 series's legs and 33% of the middle Legacy 600/650's.
Which flies longer trips, the Challenger 600 series or the Legacy 600/650?
The Legacy 600/650, by 10 nm on the median leg: 508 nm for the middle aircraft, against 498 nm for the Challenger 600 series. 37% of Challenger 600 series legs and 36% of Legacy 600/650 legs were under 300 nm, a gap of 1 percentage point; 27% and 28% were over 900 nm.
Does this comparison include the Challenger 605?
Yes. The tracking data doesn't tell the Challenger 600, Challenger 601, Challenger 601-3A, Challenger 601-3R, Challenger 604, Challenger 605 and Challenger 650 apart, so the Challenger 600 series figures here cover all of them. The specs table names a figure’s variants where the sources separate them.
Does this comparison include the Legacy 650?
Yes. The tracking data doesn't tell the Legacy 600 and Legacy 650 apart, so the Legacy 600/650 figures here cover all of them. The specs table names a figure’s variants where the sources separate them.
