Key takeaways
- The Falcon 6X is Dassault’s big twinjet: 5,500 nm range, up to 16 passengers and, according to the manufacturer, the widest and tallest cabin in business aviation.
- Fastest way to identify it: two tail engines plus a cruciform tail instead of a T-tail – that rules out the three-engine Falcons and the T-tail competition.
- It came out of a setback: the Falcon 5X failed in 2017 because of the Silvercrest engine, and the 6X took over the concept with a longer fuselage and Pratt & Whitney power.
- Still young in service: certified in August 2023, entered service at the end of November 2023 – the fleet is still growing.
- In a flight tracker you filter by the code FA6X.

Identifying features
Is this really the aircraft type in front of you?
- Two engines on the sides of the rear fuselage – unlike the Falcon 7X, 8X and 900, there is no third engine in the tail
- A strikingly tall, voluminous fuselage: the cabin is 2.58 m wide and 1.98 m high, and you can see that from the outside
- No T-tail: the horizontal stabilizer sits on the vertical stabilizer a little above the fuselage as a cruciform tail, not at the very top like on Gulfstream and Bombardier Global jets
- A long row of very large cabin windows, plus a skylight in the roof above the galley in the forward section
- Swept wing with upturned winglets and a pointed Falcon nose
- Listed in tracking services as FA6X; the three-engine models appear as FA7X and FA8X
Updated: October 2026 – A white business jet taxis off the apron, and at first glance it looks like a Falcon: pointed nose, swept wing, horizontal stabilizer sitting a little above the fuselage on the vertical stabilizer. But there are only two engines hanging off the tail, and the fuselage looks strikingly tall and bulky. Then you are very likely looking at the Dassault Falcon 6X – the big twinjet from Bordeaux, whose cabin is wider and taller, according to the manufacturer, than that of any other purpose-built business jet. Here is how to tell it from its three-engine siblings and from the competition from the US and Canada, and where you have a good chance of a sighting.
Tick off the FA6X in your hangar
With Planetrack you log every Falcon sighting with photo, registration, airport and spot, and build your own business jet collection. Planetrack is launching soon – join the waitlist and get early access.
What is the Dassault Falcon 6X?
The Falcon 6X is a twin-engine long-range business jet from Dassault Aviation. Depending on the layout, it seats 12 to 16 passengers in up to three cabin zones. Dassault quotes a range of 5,500 nautical miles, or about 10,190 kilometers with eight passengers on board. That takes it nonstop from Paris to Beijing or from Geneva to New York and well beyond – without quite entering the ultra-long-range class of the Falcon 8X.
Its big selling point is the cabin: 12.30 meters long, 2.58 meters wide and 1.98 meters high. Dassault markets it as the widest and tallest cabin in business aviation, meaning aircraft designed specifically as business jets. Add 30 particularly large windows and a skylight in the cabin roof above the galley – a detail that practically did not exist on business jets until then.
The backstory: from the 5X to the 6X
The 6X is a fresh start. Its predecessor, the Falcon 5X, was unveiled in October 2013 and was supposed to fly with Safran’s new Silvercrest engine. The engine fell behind schedule, however, and did not reach the promised performance. Dassault froze the program in 2016, let the 5X make its first flight in July 2017 with interim engines and pulled the plug in December 2017: the 5X was canceled and the Silvercrest contract terminated.
In the same month Dassault launched the Falcon 6X. It takes over the basic concept of the 5X with a wide fuselage and digital flight controls, but gets a cabin section stretched by about half a meter and PW812D engines from Pratt & Whitney Canada. The design was publicly unveiled in February 2018. Dassault and Safran settled the dispute over the failed engine in September 2018 with a compensation payment.
The prototype took off for its first flight on March 10, 2021 at Bordeaux-Mérignac. The plant at Bordeaux-Mérignac Airport is Dassault’s final assembly and test center for the Falcon family. After a good two years of testing with about 1,500 flight hours, including cold-weather trials in Canada, EASA and the FAA granted type certification in August 2023. On November 30, 2023, Dassault announced entry into service. Service entry had originally been planned for the end of 2022; supply chain problems pushed it back by about a year.
The three features that are enough to identify it
Large business jets often look strikingly similar on the apron. With the 6X, three observations get you there quickly.
Count the engines
Two engines on the sides of the rear fuselage, no air intake on top of the fuselage. That immediately rules out the three-engine Falcon 7X, 8X and 900.
Look at the tail
On the 6X the horizontal stabilizer sits on the vertical stabilizer a little above the fuselage as a cruciform tail, similar to the big three-engine Falcons. The Gulfstream G650 and G700 and the Bombardier Global jets, on the other hand, carry it at the very top of the vertical stabilizer as a T-tail.
Check the fuselage shape and type code
Relative to its length, the fuselage of the 6X looks tall and sturdy, almost like on a small regional jet. Confirmation comes from the type code FA6X in the flight tracker or from a registration lookup.
The smaller Falcon 2000 is also a twinjet and has a similar tail layout. But it is noticeably shorter and slimmer, and its row of windows is much shorter. How to read registrations and which country is behind which prefix is explained in the article Understanding aircraft registrations.
Practical tip: watch the roof
The skylight of the 6X sits in the roof above the galley in the forward fuselage. You cannot see it from below on approach, but when you look down at a taxiing aircraft from an elevated deck, it is a nice bonus clue. For a reliable identification, the registration on the rear fuselage remains decisive.
Falcon 6X, 7X, 8X or 2000?
The current Falcon family is large, and the models share many design features. The table helps you sort them.
| Feature | Falcon 2000 | Falcon 6X | Falcon 7X | Falcon 8X |
|---|---|---|---|---|
| ICAO type designator | F2TH | FA6X | FA7X | FA8X |
| Engines | 2 | 2 | 3 | 3 |
| Length | much shorter | 25.68 m | 23.38 m | 24.46 m |
| Cabin width | narrower | 2.58 m | narrower | 2.34 m |
| Range (manufacturer) | shorter | 5,500 nm | 5,950 nm | 6,450 nm |
Worth noting: the 6X is longer than the Falcon 8X but flies less far. Its focus is on cabin comfort, not maximum range. If you are looking for the Falcon 8X or the Falcon 7X, watch for the third engine; the older Falcon 900 is also a three-engine jet, but noticeably shorter.
Technology you can see from the outside
The 6X takes over the digital flight controls (fly-by-wire) from the big Falcons, which Dassault brought to business aviation with the 7X. New is a control surface where Dassault draws on its fighter jet experience around the Rafale: the flaperon. It combines the functions of a flap and an aileron and works constantly with the flight control system. According to Dassault, this allows steeper approaches and an approach speed up to ten knots below that of many comparable jets. The manufacturer quotes 110 knots as the typical approach speed.
For spotters that means: the 6X comes in comparatively slowly and, according to Dassault, has a landing distance of about 744 meters at typical landing weight. That makes it at home at smaller airfields with short runways, too. In the cockpit sits the EASy avionics system with the FalconEye combined vision system, which supports approaches in poor visibility.
The two PW812D engines deliver about 13,500 lbf each according to Dassault, or roughly 60 kilonewtons of thrust. The maximum takeoff weight is a good 35 tonnes. Mach 0.90 is certified as top speed, and the maximum altitude is 51,000 feet.
Falcon 6X, Gulfstream G700 or Global?
In the segment of large long-range business jets, you mostly run into Gulfstream and Bombardier in Europe. The finder narrows down the candidates with three questions.
Quick ID: large twin-engine business jet
Dassault Falcon 6X
Two tail engines, a cruciform tail instead of a T-tail and a tall, sturdy fuselage point to the 6X. To be safe, check that there is no third engine in the tail.
Gulfstream G650 or G700
A T-tail and the typical large oval windows are the Gulfstream hallmark. Whether it is a G650 or G700 is settled by the type code.
Bombardier Global
A T-tail, a long slim fuselage and smaller windows point to a Global. Type code and length separate the Global 6000 from the Global 7500.
You recognize the Gulfstream G700 and the Gulfstream G650 by their huge oval windows and the T-tail. The Bombardier Global 6000 and the Global 7500 also carry a T-tail, and their fuselage looks more stretched and slimmer than that of the 6X. For a bigger overview, see the guide Telling business jet types apart.
Where to find the Falcon 6X
The 6X has only been in service since the end of 2023, so the fleet is still manageable and grows with every delivery. Operators include companies, private owners and charter and management firms, as well as governments: the Irish Air Corps took delivery of a 6X as its new government VIP aircraft in December 2025, and Serbia also uses the type for government flights. More on such aircraft in the article Spotting government aircraft.
France: Paris-Le Bourget Airport is an important Dassault site and Europe’s most important business jet airport. New aircraft sometimes depart from here for their customers still wearing French test registrations. In summer, Nice Airport with its heavy private jet traffic on the Côte d’Azur is also worth a visit.
Switzerland: Geneva Airport is one of the best addresses for large Falcons all year round, and 6X jets are already registered in Switzerland, too. Zurich Airport sees a rush of large business jets around the World Economic Forum in January.
Germany and Austria: Major trade fairs, summits and the winter season bring long-range bizjets to Munich, Frankfurt, Salzburg or Vienna. A 6X there is still a sighting you are happy about, though.
| Location | Chance of a hit | Why |
|---|---|---|
| Paris-Le Bourget | high | Important Dassault site, lots of business jet traffic |
| Geneva | high | Heavy business jet traffic all year, Swiss 6X |
| Zurich (January, WEF) | medium to high | Many long-range business jets in a short time |
| Nice (summer) | medium | Seasonal private jet traffic |
| Germany, Austria | low to medium | Irregular individual arrivals |
No flight schedules, young fleet
Business jets do not appear in any published flight schedule, and some operators have their data filtered in flight trackers. The 6X fleet is also growing continuously. Plan with probabilities instead of fixed times and keep checking for FA6X during your session.
How to follow flights live is explained in the guide to flight tracking with ADS-B. You can track down a specific registration with the tips in Tracking an aircraft by registration.
Never miss another 6X
Set up a sighting alert for the FA6X type or individual registrations – Planetrack notifies you as soon as a Falcon 6X is on approach or lands. Planetrack is launching soon – join the waitlist here.
Spotting in Geneva, Zurich and Le Bourget
In Geneva, the observation deck is the obvious starting point; with just one big runway, every business jet has to come past. You will find more locations in the guide Plane spotting in Geneva. In Zurich, the Butzenbüel and Spectator Deck B are good places to start.
In Le Bourget you combine spotting with history: from the Musée de l’Air et de l’Espace you have the airport operations in view. Every two years Le Bourget becomes the stage for the Paris Air Show, where Dassault traditionally shows its Falcons prominently.
Ready for the 6X hunt?
- I checked whether a trade fair or summit is currently taking place at the airport I’m heading to.
- I have a flight tracker open with a filter for FA6X.
- I know the likely runway direction in use.
- My vantage point is publicly accessible and allowed.
- I brought enough focal length for aircraft on distant aprons.
How to estimate the runway direction in advance is covered in Understanding runway direction in use at an airport. Whether your vantage point is legally safe is answered in the article Is plane spotting allowed?.
Photo tips specifically for the Falcon 6X
At a good 25.7 meters, the 6X is large for a business jet, but it still stays small next to airliners. A few points help.
Plan for more focal length
Business jets often park on remote aprons. To fill the frame you need much more focal length than for airliners – see the guide Focal length for plane spotting for pointers.
A side profile shows the fuselage
What makes the 6X special is its tall, wide fuselage. A clean side profile with both tail engines and the cruciform tail makes the type unmistakable in the photo.
White needs light at your back
Most 6X jets are painted mostly white. With the sun behind you, windows and contours stay visible; expose a little tighter if anything.
Be ready at touchdown
Thanks to its low approach speed and short landing distance, the 6X slows down quickly. Be ready before it disappears behind hangars.
When the light works at your spot is shown by the guide Planning the sun position for your photo spot. How rare your sighting is, you can judge with the article Judging how rare a sighting is.
Common mix-ups and how to rule them out
It points to the Falcon 6X if …
- two engines hang on the sides of the rear fuselage and there is no third one in the tail
- the horizontal stabilizer sits on the vertical stabilizer a little above the fuselage, not at the very top
- the fuselage looks strikingly tall and sturdy
- the flight tracker lists FA6X as the type
Take a closer look if …
- the aircraft looks much shorter and slimmer – then it is more likely a Falcon 2000
- you only see the side and the tail is hidden – the third engine of a 7X or 8X is easily overlooked then
- you only see it from a great distance on the apron
It is not a Falcon 6X if …
- you see three engines – then it is a Falcon 7X, 8X or 900
- a T-tail is visible – then it is more likely a Gulfstream or Bombardier Global
- the engines hang under the wings – then it is, for example, a Boeing Business Jet
How type codes like FA6X are built is explained in the article IATA and ICAO codes explained.
Conclusion
The Falcon 6X is Dassault’s answer to the question of how much cabin fits into a twin-engine business jet. After the end of the 5X, it arrived late but with a clear profile: a wide, tall fuselage, two engines, fly-by-wire and flaperons on the wing. For spotters it is still a comparatively fresh sighting that, with the growing fleet, shows up more and more often at airports like Le Bourget, Geneva and Zurich.
In brief
Two tail engines, a cruciform tail instead of a T-tail and a bulky fuselage: that is the Falcon 6X. If you are searching for one, filter by FA6X and plan around business jet hotspots like Le Bourget, Geneva and Zurich.
Summary
- The Falcon 6X first flew on March 10, 2021 at Bordeaux-Mérignac, was certified by EASA and the FAA in August 2023 and entered service at the end of November 2023.
- It combines a wide, tall fuselage with two PW812D engines and digital flight controls; new are flaperons, where Dassault draws on its fighter jet experience.
- Two tail engines set it apart from the Falcon 7X and 8X, and the cruciform tail without a T-shape sets it apart from the Gulfstream G700 and Bombardier Global.
- Besides private and charter operators, governments also use the type, for example Ireland for VIP transport.
Frequently asked questions
What is the ICAO type designator of the Falcon 6X?
The Falcon 6X is filed under FA6X. Its three-engine siblings have their own codes: FA7X for the Falcon 7X and FA8X for the Falcon 8X. In flight trackers you can therefore use FA6X to filter specifically for the twinjet.
Is it true that the Falcon 6X has the widest cabin of all business jets?
Dassault markets the cabin, at 2.58 meters wide and 1.98 meters high, as the widest and tallest in business aviation. That refers to aircraft designed specifically as business jets. Converted airliners such as the Boeing Business Jet naturally have an even wider fuselage but play in a different weight class.
What was the Falcon 5X?
The Falcon 5X was the predecessor in the program. It was unveiled in 2013 and was supposed to fly with Safran’s Silvercrest engine. Because the engine did not meet expectations, Dassault stopped the project in December 2017 and instead launched the 6X with a slightly stretched fuselage and Pratt & Whitney Canada engines.
How do I tell a Falcon 6X from a Falcon 8X?
Count the engines. The Falcon 8X has three, with the third one in the center of the tail and an air intake on top of the fuselage. The 6X has only two, on the sides of the fuselage. The fuselage of the 6X also looks taller and bulkier.
What engines does the Falcon 6X have?
Two Pratt & Whitney Canada PW812D engines. Dassault quotes about 13,500 lbf per engine, or roughly 60 kilonewtons of thrust. The engine belongs to the PW800 family, which also powers other large business jets.
What are the Falcon 6X’s flaperons?
A control surface where Dassault brings in know-how from fighter jet construction. It combines the effect of a flap and an aileron and works together with the digital flight controls. According to Dassault, this makes steep approaches easier and allows lower approach speeds than many comparable jets.
Where can I see a Falcon 6X?
Most likely at airports with lots of business travel, such as Geneva, Zurich, Nice or Paris-Le Bourget, where Dassault operates a large site. Since the fleet is still young and growing, your chances improve from year to year.
Collect the Dassault Falcon 6X, don’t just see it
Post a photo with registration, type, airport and spot, check off the type in your hangar and get an alert when a registration you are looking for lands. Planetrack is launching soon – join the waitlist and get early access.

Airports, manufacturers, airline groups and alliances – who is behind them and what you should know as a spotter.
Dassault Aviation
Dassault Aviation builds fighter jets and the Falcon family of business jets in France. For spotters, that means Rafales at air shows and military airfields, Falcons at every larger airport with business travel – and a few features at the tail let you tell the models apart with confidence.
AirportParis-Le Bourget Airport
Lindbergh landed here in 1927, the 1937 Art Deco terminal stands here, and every two years the aviation industry shows its latest products here at the Paris Air Show. Scheduled flights are long gone at Le Bourget – but Falcon, Gulfstream and Global appear in a density that hardly any other European airport matches.
AirportGeneva Airport
Switzerland’s second-largest airport has just one runway – but the longest in the country. Geneva lives on easyJet, SWISS and one of Europe’s strongest business aviation scenes. With the free Panorama terrace and the train station right at the terminal, it is also one of Switzerland’s most convenient spotting destinations.
AirportZurich Airport
Switzerland’s largest airport has three runways in three directions, an operating concept that changes with the time of day and the weather, and an official network of spotting points around the fence. If you know the concepts, you almost always stand in the right place in Zurich.
Where to see the Dassault Falcon 6X
Specific vantage points with the runway configuration, light times, coordinates and an honest take on whether the trip is worth it.
Observation terrace at Geneva Airport
On the fourth floor of Terminal 1 you look over the apron onto Switzerland’s longest runway and the Jura range behind it. The Terrasse Panorama costs nothing, you get in without security screening – and thanks to business aviation, an easyJet base and long-haul guests it is rarely boring. The only catch: it is open only from mid-March to the end of October.
Spotting hillButzenbüel and the spotter hill at Zurich Airport
The classic spotter hill at the Heligrill on the west side of Zurich Airport has been gone since September 2023, and the Butzenbüel is a park hill behind The Circle – not a spotter point. Here you learn what is going on with both places and where you can legally spot today in the west and around the fence.
Observation deckObservation Deck B at Zurich Airport
On the roof of Dock B you stand in the middle of the action at Switzerland’s largest airport: SWISS long-haul, taxiing traffic right below you and heavy takeoffs on the longest runway. Probably Switzerland’s best-known legal spotting place – with security screening, admission and clear rules.
MuseumMusée de l’Air et de l’Espace at Paris-Le Bourget Airport
One of the world’s largest aviation museums stands in Paris’s old 1937 airport terminal: two Concorde, a walk-through Air France 747, A380 number four and, from the terraces, a view of Europe’s most important business jet airport. Here is how to get the most out of your visit as a spotter.
