Dassault Falcon 6X Vs Gulfstream G500

Gulfstream G500 exterior in flight

The Dassault Falcon 6X is one of the newest jets ready to hit the market. The 6X builds on the success of the larger Falcon 7X and 8X. In comparison, the Gulfstream G500 is the worthy opponent to the new 6X.

The G500 is also a relatively new aircraft in the world of private jets, with deliveries having started in 2018.

In this comparison we will look at the performance of each aircraft, along with the range and ground performance. Then the interior dimensions will be compared along with the interiors. Finally the hourly charter price and purchase cost will be compared.

Performance

The Dassault Falcon 6X is powered by two Pratt & Whitney Canada PW812D engines. Each engine is capable of producing 13,460 lbf of thrust.

Conversely the Gulfstream G500 is powered by two Pratt & Whitney PW814GA engines. Each engine is capable of producing 15,144 lbs of thrust.

As a result both aircraft can cruise at a maximum altitude of 51,000 feet. Additionally, both aircraft are capable of cruising at a maximum speed of 516 knots. This translates to Mach 0.9. For reference, Mach 1 is the speed of sound. These are, therefore, some of the fastest business jets in the world only being beaten out by the Cessna Citation X.

An area where these aircraft do differ, however, is their fuel burn. The Dassault Falcon 6X has a fuel burn of 419 Gallons per Hour (GPH), compared with 430 Gallons per Hour(GPH) for the Gulfstream G500. Over the long run this minor difference can really start to add up. (How much does it cost to fuel a private jet?)

Range

When it comes to the maximum distance that these aircraft can fly without needing to refuel, the Falcon 6X is the clear victor.

The Dassault Falcon 6X has a maximum range of 5,500 nautical miles compared with a maximum range of 5,300 nautical miles for the Gulfstream G500.

This is a very minor difference in range ability. As a result, an additional 200 nautical miles in range is unlikely to make the Falcon 6X capable of a significant number of missions that the Gulfstream G500 is unable to complete.

Use this tool to see how far each aircraft can take you.

Ground Performance

On the ground the G500 is able to take off in a shorter distance but requires more runway to land.

The Gulfstream G500 has a minimum take off distance of 5,300 feet. This beats out the Falcon 6X which has a minimum take off distance of 5,480 feet.

When it comes to landing the order is reversed. The Falcon 6X wins here with a minimum landing distance of 2,480 compared with the 3,100 feet runway required to land the G500.

Is this going to be noticeable in the real world? No. Whichever airport the aircraft lands at it will need to take off again. Therefore, the Falcon 6X being able to land in a shorter distance but needing more runway to take off isn’t a significant benefit over the G500.

Rather, the benefit swings in favor of the Gulfstream. However, having said that, the benefit is very slight. A difference of 180 feet is less than 5% of the minimum take off distance of the Falcon 6X.

Furthermore, it is unlikely that there will be a situation in which an airport can accommodate the G500 but not the Falcon 6X.

Interior Dimensions

Next up is the size of the cabin. A larger cabin allows for more passengers, more privacy, more features and more comfort.

There are three measurements that are relevant here; the length, width and height. A longer cabin allows for more living spaces and customization. A wider cabin allows for a wider aisle, wider seats and more shoulder room. And finally, height. A taller cabin allows passengers to stand up more easily and more around. In addition to this, a taller cabin makes the entire environment feel more spacious.

The Gulfstream G500 beats out the Falcon 6X when it comes to interior cabin length. The G500’s cabin measures 14.5 meters in length compared with the 12.3 meters of the Falcon 6X.

However, the order is reversed for the next two measurements.

The Falcon 6X is wider than the G500 (2.58 meters to 2.31 meters) and ever so slightly taller (1.98 meters to 1.88 meters).

The difference in length between these aircraft is pronounced when looking at the overall passenger capacity. The G500 has a maximum passenger capacity of 19 while the Falcon 6X can carry up to 16 passengers.

Furthermore, the Gulfstream G500 is able to carry more baggage with a total baggage capacity of 175 cubic feet. In comparison the Dassault Falcon 6X is able to carry up to 155 cubic feet of baggage.

Interior

Given that these aircraft can comfortably carry you between continents, it is no surprise that these are some of the most luxurious cabins in the sky.

Both cabins are extremely quiet with the cabin noise levels in the Falcon 6X being just 49 decibels and the G500 at 50 decibels. Realistically a difference of 1 decibel is unlikely to be noticed by the vast majority of passengers.

However, a measurement that might be noticed is the cabin altitude. A lower cabin altitude is beneficial in improving the overall cabin environment, along with reducing the effects of jet lag. Therefore, the lower the cabin altitude the better.

When cruising at 51,000 feet the Falcon 6X has a cabin altitude of 6,000 feet compared to the just 4,850 feet of the Gulfstream G500. Cabin altitude is an area (one of many) that Gulfstream consistently excel at – a low cabin altitude.

Dassault Falcon 6X Interior

Common space within the 6X has been allocated in order to allow teams to meet and confer. Dassault have built the cabin to be flexible between living and working space. This allows you to stay comfortable while achieving more.

The cabin being 102 inches wide also provides passengers with more elbow room, aisle space and more comfortable divans. More space has been allocated for individual seating and greater privacy has been integrated. These details are most notable in the rear cabin during overnight flights.

When cruising at 41,000 feet the 6X has a cabin altitude of just 3,900 feet. This ensures that you will feel refreshed at the end of a long flight. The air filtration system on the Falcon 6X keeps you breathing easier and gets fresh air into your lungs. The entire volume of cabin air can be refreshed in under three minutes. Furthermore, Dassault have been able to make the interior of the cabin have some of the lowest sound levels on the market. According to Dassault, the sounds levels are “below the level of normal conversation”.

The 6X has 30 large windows throughout the cabin. Windows are closely spaced to increase the field of view when looking out the window. The volume of natural light entering the cabin is sure to elevate your mood and enlarge your perspective. Incredibly, Dassault have managed to integrate a skylight into the cabin. The first ever in a business aircraft. This drenches the entrance and galley areas in natural light.

A critical aspect of business jets in their connectivity to the outside world. The cabin can be controlled from your own personal device, allowing you to control lighting, volume level and entertainment options. The connectivity onboard will make you feel like your at your own home or office.

Gulfstream G500 Interior

100% fresh air, a maximum cabin altitude of 4,850 feet and a cabin noise level of 50 decibels provides a peaceful environment. This environment is lit by fourteen signature Gulfstream oval windows. Combined, these windows provide an abundance of natural light and sweeping views of the world below. Adding these factors together ensure that you arrive at your destination refreshed and with minimal jet lag.

Gulfstream’s Cabin Management System allows passengers to control lighting, temperature and media right from their seats. The seats are able to be converted to lie-flat beds. Therefore, the G500 is a great space to work, dine and relax.

Charter Price

The difference in charter price between these two aircraft is significant. However, note that the Falcon 6X is yet to hit the charter market.

The estimated hourly price for the Falcon 6X is $10,000 when chartering. Compared with the Gulfstream G500 which has an estimated hourly charter rate of $7,350.

However, please note that there are many factors that can impact the price of a charter flight.

Purchase Price

The purchase price of both of these aircraft is remarkably similar, with a difference of just $2 million on the list price.

The Falcon 6X has a new list price of $47 million. In comparison the Gulfstream G500 comes in with a new list price of $45 million.

Therefore, the question remains, is a skylight alone worth $2 million?

Unfortunately we are unable to look at the depreciation of these aircraft or the pre-owned cost. This is due to the Falcon 6X not being available on the market yet.

Summary

So, which is best?

Both these aircraft are capable of completing similar missions. They can both fly similar distances without needing to refuel. Both can cruise at the same speed. The fuel burn is nearly identical.

Therefore, where do these aircraft differ? The answer comes down to the interior. If you base the choice on numbers then the G500 is the one to go for. It is less expensive to buy, less expensive to charter and has a lower cabin altitude.

However, there is something special about the interiors of Falcon aircraft. The Falcon 6X is wider and taller. Therefore, if you are flying with just a few passengers this might be the better choice for a more comfortable cabin.
