The Falcon 2000 was Dassault's answer to the wide cabin Challenger 600 series. It roughly resulted from removing the middle engine from the Falcon 900, which necessitated a re-design of the rear fuselage. This creates a funny tail cone: a kind of upturned nose, ending in the APU exhaust. The typical Falcon cockpit windows and horizontal stabilisers with anhedral (pointing down) make recognition from similar types easy.

To differentiate between the Falcon 2000 subtypes you have to look at

• details on the engine nacelles
• the presence of winglets
• the span of the slats on the wing's leading edge

The first version of the Falcon 2000 has General Electric CFE738 engines. While the engines have nearly straight fan blades, it is easier to just look at the nacelles to recognise the Falcon 2000. At the front, just behind the main air intake, two small rectangular air intakes are visible. The PW308 equipped aircraft, based on the 2000 EX, don't have these.

Note that Falcon 2000s can be fitted with winglets afterwards. However, this does not change the designation.

The Falcon 2000EX has Pratt & Whitney PW308C engines instead of General Electric’s CFE738. The former have more curved compressor blades, while the original engines have nearly straight blades. Just look at the front of the engine! Nevertheless, it is much easier to look at the presence or absence of the small rectangular air intakes at the front of the nacelles: the Falcon 2000EX does not have them.

Falcon 2000EX-EASy is the marketing name for the 2000EX with the Honeywell EPIC EASy avionics suite. This is not visible from the outside.

Like the Falcon 900DX, the Falcon 2000DX was offered as a less expensive version of the Falcon 2000EX. To differences are only inside, however.

The Falcon 2000LX is a Falcon 2000EX-EASy with winglets. Hence, by adding winglets a Falcon 2000EX-EASy becomes a Falcon 2000LX. Note that Falcon 2000EXs can also be equipped with winglets, but these are not called Falcon 2000LX.

The Falcon 2000S is a version with short take-off and landing performance. To enable this, the aircraft has slats across the full wing leading edge, but in two parts. Hence, it can only be recognised when the slats are extended.

The Falcon 2000LXS is the follow-up of the Falcon 2000LX, and is essentially a 2000LX with slats across the full wing leading edge like the 2000S. The main difference between both aircraft is in the range: the 2000S has a smaller fuel capacity than the 2000LXS.
