G280 vs GIV: 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 G280 and the GIV. The clearest difference is short runways: the middle G280 at 13%, the middle GIV at 39%, 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 GIV at 1.9 : 1, the middle G280 at 1.6 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Choosing between a G280 and a GIV?
Check both tails, not the types.
Enter the two tails on your shortlist. TailCheck grades each one on Fatigue, Corrosion, Engines and brakes, and Utilization against its own type, then puts them side by side.

36% of G280 legs and 34% of GIV legs were under 300 nm, a gap of 2 percentage points; 22% and 32% were over 900 nm.

G280 vs GIV: 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 GIV yet, so its manufacturer rows show a dash.

G280 vs GIV: questions
Which is flown more, the G280 or the GIV?
The GIV, by about 18 estimated hours a year: the middle GIV flew ≈189 h a year, the middle G280 ≈171 h. That is a fleet median: the middle half of GIVs logged 120–358 h and of G280s 113–248 h, so one aircraft can sit far from its type. In flights, the medians are 9 a month for the G280 and 9 for the GIV.
Which lands more often for its hours, the G280 or the GIV?
The G280: its middle aircraft flies 1.6 hours per landing, against 1.9 for the GIV, 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 34% of the middle G280's legs and 33% of the middle GIV's.
Which flies longer trips, the G280 or the GIV?
The GIV, by 71 nm on the median leg: 560 nm for the middle aircraft, against 489 nm for the G280. 36% of G280 legs and 34% of GIV legs were under 300 nm, a gap of 2 percentage points; 22% and 32% were over 900 nm.
Which spends more nights by the sea, the G280 or the GIV?
The GIV, by 1 percentage point: its middle aircraft spends 2% 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.
Does this comparison include the G300?
Yes. The tracking data doesn't tell the GIV, GIV-SP, G300, G400, G350 and G450 apart, so the GIV figures here cover all of them. The specs table names a figure’s variants where the sources separate them.
