Both aircraft can fly at a maximum altitude of 51,000 feet, allowing them to avoid turbulence and weather disturbances, increase fuel efficiency, and reduce travel time.

However, the Gulfstream G500 has a slightly higher rate of climb, reaching 4,090 feet per minute compared to the Falcon 900LX’s 3,880 feet per minute. This means the G500 can ascend faster and reach cruising altitude sooner, which can be crucial for time-sensitive trips or to avoid adverse weather conditions.

In terms of cruise altitude, the Falcon 900LX has an initial altitude of 37,000 feet, while the G500 can start at 43,000 feet. This gives the G500 an advantage in avoiding air traffic congestion and potentially providing a smoother ride for passengers.

When it comes to fuel efficiency, the Falcon 900LX burns 260 gallons per hour, while the G500 uses 353 gallons per hour. The Falcon 900LX’s lower fuel burn translates to reduced operating costs, and over the course of 300 flight hours per year, this could save up to $276,000 if Jet A fuel were to cost $5 per gallon.

However, the higher fuel burn on the G500 is offset by its more powerful Pratt & Whitney Canada engines, which produce a total trust output of 30,288 pounds, compared to the Falcon 900LX’s 15,000 pounds.

In terms of speed, the G500 has a slightly faster high-speed cruise of 516 knots compared to the Falcon 900LX’s 498 knots. This extra speed also translates to long-range cruise speed with the Falcon 900LX limited to 458 knots compared to the G500’s 488 knots.


When it comes to private jets, range is a crucial factor to consider, especially for international travel.

The Dassault Falcon 900LX has a range of 4,750 nautical miles (8,800 kilometers) while the Gulfstream G500 has a range of 5,300 nautical miles (9,816 kilometers).

For example, starting in New York, the Falcon 900LX can reach cities such as Paris or Istanbul.

The G500 has a further range, meaning it can reach cities such as Cairo or Tel Aviv.

Similarly, starting in London, the Falcon 900LX can reach destinations such as New York or Los Angeles. The G500, on the other hand, can fly nonstop to Bangkok or Cape Town.

It is important to note that these figures are based on the manufacturer’s best-case scenario and assume perfect weather conditions and the minimum amount of weight onboard.

Several factors impact the maximum range of a private jet, including weather conditions, weight, and wind. Additionally, deviations from optimal flight paths and air traffic congestion can also impact the range of a private jet.

Ground Performance

The Falcon 900LX can take off in a minimum distance of 5,360 feet, while the G500 can do so in 5,300 feet.

While the difference between the two may seem negligible, having a shorter take-off distance can make a significant difference in accessing smaller airports that are not available to larger aircraft. Accessing these smaller airports can reduce overall travel time, and give travelers more flexibility in planning their trips.

Additionally, the Falcon 900LX has a minimum landing distance of 2,415 feet, while the G500 requires a longer distance of 3,100 feet. This makes the Falcon 900LX more suitable for airports with shorter runways or limited space.

It’s important to keep in mind that the difference of 60 feet in take-off distance may not be noticeable in the real world, and it ultimately comes down to individual needs and preferences.

Interior Dimensions

Starting with interior length, the Falcon 900LX’s cabin measures 33.2 feet (10.11 meters), while the G500’s measures 47.6 feet (14.5 meters). The G500’s longer cabin provides more space for passenger comfort and allows for more configuration possibilities, such as adding additional seating or creating separate cabin areas for meeting rooms or bedrooms.

In terms of interior width, the Falcon 900LX measures 7.68 feet (2.34 meters), while the G500 measures 7.6 feet (2.31 meters). While the difference is minimal, the G500’s slightly narrower cabin may be less spacious for passengers.

Regarding cabin height, both aircraft offer the same ceiling height of 6.2 feet (1.88 meters). However, the G500 has a larger fuselage cross-section, which provides a more spacious cabin atmosphere and allows for a wider range of seating arrangements.

The Falcon 900LX can accommodate up to 14 passengers, while the G500 has an official maximum occupancy of 19. However, it’s important to consider that the number of passengers that can comfortably fit in the aircraft’s cabin may vary based on the chosen configuration.

When it comes to luggage capacity, the Falcon 900LX can accommodate 127 cubic feet (3.6 cubic meters) of luggage, while the G500 has space for up to 175 cubic feet (4.9 cubic meters). This additional space for luggage may make a significant difference for extended trips requiring a large amount of baggage.


The Dassault Falcon 900LX was first delivered in 2010, while deliveries for the Gulfstream G500 started in 2018. One of the notable differences between these two aircraft is their maximum cabin altitude.

The Falcon 900LX’s maximum cabin altitude is 8,000 feet compared with just 4,850 feet for the G500.

Moreover, the G500 can maintain a sea level cabin until 31,900 feet, which is higher than the 900LX’s sea level cabin altitude of 25,300 feet.

A lower cabin altitude provides more passenger comfort and reduces the likelihood of altitude sickness, fatigue, and jet lag. The G500’s ability to keep the cabin at a lower altitude for longer periods provides passengers with a more comfortable flying experience.

Dassault Falcon 900LX

The interiors of Falcon aircraft have always been breathtaking. Dassault are able to perfectly blend style with functionality. The 900LX is no exception.
