Citation CJ4 vs Citation Longitude: how the two fleets are really flown
On every chapter's lead measure the Citation CJ4 and the Citation Longitude sit further apart than the middle half of either fleet. The clearest difference is short runways: the middle Citation CJ4 at 2%, the middle Citation Longitude at 22%, with no overlap between their middle halves.

Fatigue
On hours per landing, the types sit further apart than the middle half of either fleet spans: the middle Citation Longitude at 1.6 : 1, the middle Citation CJ4 at 1.3 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Citation CJ4 vs Citation Longitude: 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 Citation Longitude: questions
Which is flown more, the Citation CJ4 or the Citation Longitude?
The Citation Longitude, by about 575 estimated hours a year: the middle Citation Longitude flew ≈667 h a year, the middle Citation CJ4 ≈92 h. That is a fleet median: the middle half of Citation Longitudes logged 168–752 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 35 for the Citation Longitude.
Which lands more often for its hours, the Citation CJ4 or the Citation Longitude?
The Citation CJ4: its middle aircraft flies 1.3 hours per landing, against 1.6 for the Citation Longitude, 0.3 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 39% of the middle Citation Longitude's.
Which flies longer trips, the Citation CJ4 or the Citation Longitude?
The Citation Longitude, by 64 nm on the median leg: 430 nm for the middle aircraft, against 366 nm for the Citation CJ4. 44% of Citation CJ4 legs and 39% of Citation Longitude legs were under 300 nm, a gap of 5 percentage points; 14% and 24% were over 900 nm.
Which spends more nights by the sea, the Citation CJ4 or the Citation Longitude?
The Citation Longitude, by 9 percentage points: its middle aircraft spends 9% 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 Citation Longitude?
The manufacturers quote 2,165 nm for the Citation CJ4 and 3,500 nm for the Citation Longitude. Those are book figures at stated conditions; how far the fleets actually fly is in the trip-length mix above.
