When it first came on the market, the G450 replaced the G400 business jet. Offering updated Honeywell Primus Epic PlaneView avionics and a pair of next generation Rolls-Royce Tay 611-8C engines, for over a decade the G450 built upon the successful legacy of the original Gulfstream GIV and GIV-SP Long-Range jets.

But how can you tell if the G450 is the right aircraft for you? Let’s look at some important points all prospective buyers should know about the Gulfstream G450.

How much does a Gulfstream G450 cost?

Factors influencing the asking price of a used Gulfstream G450 include the year of production, hours flown, flight cycles, avionics and the time remaining before any major maintenance events (such as engine overhauls and hot-section inspections), and the availability of attractive candidates on the used aircraft market at any particular time.

The existence, or lack of in-flight connectivity and entertainment systems may also influence a particular Gulfstream G450’s price.

What is the range and payload capability of a Gulfstream G450?

Assuming the G450 for sale is within budget, buyers can further narrow the selection of aircraft available to them by assessing how the range and payload capability of an aircraft fits with their mission need.

According to Conklin & de Decker, when carrying four passengers the range of the Gulfstream G450 is 4,425nm, and with all passenger seats occupied the range is 4,070nm.

From New York, the Gulfstream G450 can fly non-stop to Rome, Moscow or Sao Paulo, for example.

While it offers a maximum cruise speed of 500kts, according to Conklin & de Decker, the long-range cruise is 445kts.

With fuel capacity for up to 29,281lbs fuel, fully-fuelled the G450 can carry 2,719lbs additional payload.

In other words, when fully-fuelled the G450 could comfortably carry a three-man crew, plus eight passengers (each weighing 200lbs) and still have around 500lbs spare for luggage.

What are the cabin measurements for the Gulfstream G450?

So how comfortable is the G450 when traveling long-range business trips?

Commonly configured to carry 14 passengers in executive configuration, the cabin of the Gulfstream G450 offers plenty of space for flights that could easily last more than eight hours non-stop.

A galley (which might be located to the rear or at the front of the cabin) and fully-enclosed lavatory is standard. Some G450s may be configured to offer two lavatories. And depending on the layout, up to six seating units can be berthed for comfortable sleeping on long-distance flights.

In terms of cabin dimensions, the G450 shares its cabin cross-section with the larger, longer-range Gulfstream G500 and G550 jets. With a cabin height of 6.2ft and a width of 7.3ft (per Conklin & de Decker), the cabin occupants will certainly appreciate the roominess of the G450. And with a cabin length of 45.1ft, the aircraft affords its owners an overall 1,658cu.ft. of cabin volume. Moreover, the aircraft offers 169cu.ft. internal luggage space.

What is the Gulfstream G450’s runway performance?

Which airports will you visit with your G450?

When you’re shopping for a Long-Range jet, the airport options become fewer since the runways need to be longer than for smaller jets.

According to Conklin & de Decker, the Gulfstream G450 requires a balanced field length of 5,578ft, and the factored landing distance of this aircraft is 4,417ft.

(The published balanced field length considers distance required for acceleration to rotation speed before aborting a take-off and stopping by the calculated distance.)

So, how does the G450 compare against its competitors?

FAQ: Gulfstream G450

How many passengers can fly on a G450?
Though a Gulfstream G450 can seat as many as 19 passengers, a much more comfortable interior lay-out allows for 14. The cabin can be divided into three different sections, and the jet can comfortably sleep five-six overnight travellers.
How many Gulfstream G450s are in operation?
Manufactured between 2003 and 2017, Gulfstream built 359 Gulfstream G450s. North America is home to about 60% of the fleet, while Asia-Pacific accounts for another ~25% of the fleet, highlighting the jet’s popularity for its long-range capabilities.
How do I find a G450 for sale?
You can find Gulfstream G450 jet for sale via AvBuyer’s G450 page.
Or you can search for a dealer who specializes in Gulfstream models. They’ll provide you with a deeper knowledge of the G450 marketplace, including how the price of one jet on the market compares to others; identifying options that may not be listed on the open market; and help ensure you get the best value for your money.
Can I charter a Gulfstream G450s and try before I buy?
If you haven’t owned a Gulfstream G450 before it’s a great idea to charter first. This will help you appreciate whether this is the right aircraft for your mission profile. How far you will travel on each trip, how much baggage room you will need, and most importantly how comfortable the aircraft is for a typical trip.
Which is the best engine maintenance program for a G450?
When the time comes to renew the hourly engine maintenance program coverage, there are two choices:
Since the Gulfstream G450 is powered by a pair of TAY611-8C engines, Rolls-Royce provides an hourly engine maintenance program called CorporateCare.
Alternatively, you might prefer to enrol your aircraft with a third-party hourly maintenance cost program provider like JSSI.
When buying aircraft, look for jets which are already enrolled on such programs and check out what is covered by the existing program before buying your Gulfstream G450.
