Gulfstream GIV/G450: how 495 jets are really flown
The busiest 5% made more than 26 flights a month and the quietest 5% fewer than 3: over eight times as many, on the same type.
At the harder end, one GIV in twenty sees a freeze and a thaw on 28% or more of its nights. At the easier end, most see almost none.
The harder end, one aircraft in twenty, is at 20% or more; the easier end near none.
The hardest-worked 5% log ≈658 h a year or more; the easiest-used, ≈67 h or less. The middle aircraft sits at ≈189 h.
Fatigue
What each landing and pressurization cycle costs the structure: landings per hour and short hops.
The middle GIV flies 1.9 hours for every landing. One in twenty lands every 1.2 hours or sooner, the most cycles for its time.

US-registered aircraft only: the FAA registry gives serial number and year of manufacture for 435 of the 495 we track. Built = year of manufacture. Avionics upgrades are fitted by modification and the registry doesn’t show them, so check an aircraft’s records.
What the GIV’s certification file says
Regulators publish an operational evaluation for each type: how pilots must be rated and trained, and what training must stress.

GIV questions
How many hours a year does a GIV/G450 fly?
The median North America GIV/G450 flies about 189 estimated hours a year; the middle half sits between 120 and 358. About 1 in 20 flies more than 658.
How often does a GIV/G450 fly?
9 flights a month on 6 flying days at the median. About 1 in 20 makes more than 26 flights a month.
How long is a typical GIV/G450 flight?
The median leg is 560 nm. About 1 in 20 aircraft average more than 985 nm a leg.
How often do GIV/G450 aircraft use short runways?
At the median, 39% of departures are from fields whose longest runway is under 1.25 times the type’s takeoff distance. About 1 in 20 keep it to 11% or less.
Is a high-hours GIV/G450 a bad buy?
Not by itself. High hours on long legs are gentler on the structure than the same hours on short hops. Look at hours per landing and short-hop share alongside hours.
Can a GIV/G450 fly across the Atlantic?
Yes. In our tracking window, 215 of the 495 North America aircraft flew 1,130 nonstop crossings between the Americas and Europe or Africa. The busiest were Luton–Teterboro (88 flights), Teterboro–Paris-Le Bourget (58 flights), London Stansted–Teterboro (36 flights).
Where are most GIV/G450 aircraft based?
In North America, Teterboro is home to the most, followed by Van Nuys and Fort Lauderdale. A base is the field an aircraft touches on most of its flying days, month after month.

The Aircraft Ledger. “Gulfstream GIV/G450 fleet statistics.” Data to 31 July 2026. theaircraftledger.com/aircraft/gulfstream/giv
Method: Gulfstream GIV/G450 aircraft with most departures in North America and at least 20 tracked flights in the latest twelve full months. Flight measures, bases, routes and rankings use ADS-B tracking 1 Aug 2025 – 31 Jul 2026; corrosion and engines-and-brakes exposure use the same twelve months, or an aircraft’s record since 1 Jan 2025 when it had too few nights or departures in them. Estimated hours from time in the air. Tracking misses some flights, so counts and hours are minimums. ADS-B coverage grew over the window, so we don’t compare one year with the last. Tracking can’t tell one variant from another; the variant split, the busiest table’s variants and the age table use the FAA registry, so they cover US-registered aircraft only. We assume the longest runway at each field, so short-runway figures are conservative. Corrosion measures cover the aircraft we can place on enough nights.
