Citation CJ4 vs Phenom 300: 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 CJ4 and the Phenom 300. The clearest difference is salt air: the middle Citation CJ4 at 0%, the middle Phenom 300 at 5%.

Fatigue
On hours per landing, the gap between the types is smaller than the spread inside either fleet: the middle Citation CJ4 at 1.3 : 1, the middle Phenom 300 at 1.2 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Citation CJ4 vs Phenom 300: 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 CJ4 vs Phenom 300: questions
Which is flown more, the Citation CJ4 or the Phenom 300?
The Phenom 300, by about 180 estimated hours a year: the middle Phenom 300 flew ≈272 h a year, the middle Citation CJ4 ≈92 h. That is a fleet median: the middle half of Phenom 300s logged 96–550 h and of Citation CJ4s 62–135 h, so one aircraft can sit far from its type. In flights, the medians are 6 a month for the Citation CJ4 and 17 for the Phenom 300.
Which lands more often for its hours, the Citation CJ4 or the Phenom 300?
The Phenom 300: its middle aircraft flies 1.2 hours per landing, against 1.3 for the Citation CJ4, 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 42% of the middle Citation CJ4's legs and 45% of the middle Phenom 300's.
Which flies longer trips, the Citation CJ4 or the Phenom 300?
The Citation CJ4, by 22 nm on the median leg: 366 nm for the middle aircraft, against 344 nm for the Phenom 300. 44% of Citation CJ4 legs and 45% of Phenom 300 legs were under 300 nm, a gap of 1 percentage point; 14% and 9% were over 900 nm.
Which spends more nights by the sea, the Citation CJ4 or the Phenom 300?
The Phenom 300, by 5 percentage points: its middle aircraft spends 5% of its nights within 2 km of the coast, the middle Citation CJ4 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 CJ4 or the Phenom 300?
The manufacturers quote 2,165 nm for the Citation CJ4 and 2,010 nm (Phenom 300E) for the Phenom 300. 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 Phenom 300E?
Yes. The tracking data doesn't tell the Phenom 300 and Phenom 300E apart, so the Phenom 300 figures here cover all of them. The specs table names a figure’s variants where the sources separate them.
