Legacy 600/650 vs GIV: 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 Legacy 600/650 and the GIV. On flights a month, the middle half of Legacy 600/650s runs 8–14 and of GIVs 5–15; the medians are 10 and 9.

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 Legacy 600/650 at 1.8 : 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 GIV at 5%.
What departures ask of engines, brakes and tires: heat and height, and runway length.

Legacy 600/650 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 Legacy 600/650 or the GIV yet, so its manufacturer rows show a dash.

Legacy 600/650 vs GIV: questions
Which is flown more, the Legacy 600/650 or the GIV?
The Legacy 600/650, by about 32 estimated hours a year: the middle Legacy 600/650 flew ≈221 h a year, the middle GIV ≈189 h. That is a fleet median: the middle half of Legacy 600/650s logged 169–282 h and of GIVs 120–358 h, so one aircraft can sit far from its type. In flights, the medians are 10 a month for the Legacy 600/650 and 9 for the GIV.
Which lands more often for its hours, the Legacy 600/650 or the GIV?
The Legacy 600/650: its middle aircraft flies 1.8 hours per landing, against 1.9 for the GIV, 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 33% of the middle Legacy 600/650's legs and 33% of the middle GIV's.
Which flies longer trips, the Legacy 600/650 or the GIV?
The GIV, by 52 nm on the median leg: 560 nm for the middle aircraft, against 508 nm for the Legacy 600/650. 36% of Legacy 600/650 legs and 34% of GIV legs were under 300 nm, a gap of 2 percentage points; 28% and 32% were over 900 nm.
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.
Does this comparison include the G450?
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.
