Global 5000/5500 vs GIV: how the two fleets are really flown
On all four chapters' lead measures, the gap inside each fleet is bigger than the gap between the Global 5000/5500 and the GIV. On flights a month, the middle half of Global 5000/5500s runs 5–17 and of GIVs 5–15; the medians are 7 and 9.

Global 5000/5500 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.

Global 5000/5500 vs GIV: questions
Which is flown more, the Global 5000/5500 or the GIV?
The Global 5000/5500, by about 9 estimated hours a year: the middle Global 5000/5500 flew ≈198 h a year, the middle GIV ≈189 h. That is a fleet median: the middle half of Global 5000/5500s logged 127–445 h and of GIVs 120–358 h, so one aircraft can sit far from its type. In flights, the medians are 7 a month for the Global 5000/5500 and 9 for the GIV.
Which lands more often for its hours, the Global 5000/5500 or the GIV?
The GIV: its middle aircraft flies 1.9 hours per landing, against 2.1 for the Global 5000/5500, 0.2 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 Global 5000/5500's legs and 33% of the middle GIV's.
Which flies longer trips, the Global 5000/5500 or the GIV?
The Global 5000/5500, by 29 nm on the median leg: 589 nm for the middle aircraft, against 560 nm for the GIV. Both fleets flew 34% of their legs under 300 nm; 35% of Global 5000/5500 legs and 32% of GIV legs were over 900 nm.
Which spends more nights by the sea, the Global 5000/5500 or the GIV?
The Global 5000/5500, by 3 percentage points: its middle aircraft spends 5% of its nights within 2 km of the coast, the middle GIV 2%. Salt air is one of the corrosion inputs a TailCheck report grades for one aircraft against its own type.
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.

Method: Global 5000/5500s and GIVs with most departures in North America, ADS-B tracking. Flight measures cover 1 Aug 2025 – 31 Jul 2026; each figure is the median of its own fleet, with the middle half (25th–75th percentile). Estimated hours from time in the air.
