Dassault Falcon 20/200 (Mystère 20/Fan Jet Falcon)
The Falcon 20 was among the first generation bizjets. In the United States it was first known as the Fan Jet Falcon, whilst in the rest of the world it was marketed as Mystère 20. Later the now well-known name Falcon was adopted, and this marked the start of a whole family of business jets.
The general characteristics of the Falcon 20 are the large cockpit windows, large oval cabin windows and the horizontal stabilizer in a V-shape, so with a significant dihedral, about halfway the vertical fin.
The different versions of the Falcon 20 can be recognised by the following elements:
- the shape of the engine nacelles
- the shape of the dorsal fin
- the width of the leading edge slats
- the bottom of the fuselage
- the presence of a cargo door
Mystère 20, Falcon 20C, Falcon 20D & Falcon 20E
The prototype of the corporate jet was called Mystère 20. This was powered by two General Electric CF700 engines, which can be recognised by the ring in the air intakes, separating the core and fan flows. The nacelles also have a tab at the back.
The prototype was followed up by production versions C, D and E, which differ only in engines and fuel capacity, maximum take-off weights and a few small things. In addition, the Falcon 20E should have a different rudder, but the difference is apparently rather subtle...
The Canadian armed forces had the Falcon 20C in service as CC-117 and CE-117.
Especially for an Australian customer Dassault made a version of the Falcon 20 for operations on non-paved runways. For this purpose, the Falcon 20CC features larger, low-pressure tires. To ensure that the drag would not increase - the gear did not completely fit in the fuselage - an additional fairing body was fitted to the underside of the fuselage.
The Falcon 20 was the aircraft that helped Federal Express to grow in the early 1970. As Dassault had several unsold aircraft, the Falcons were delivered originally as passenger aircraft with windows. FedEx had them converted with a cargo door and the windows painted over. Subsequent orders were dealt with the same way.
Later other Falcon 20s were converted to cargo planes as well, but they did not receive the Falcon 20DC designation.
In order to distinguish this version the slats need to be extended. On the Falcon 20F they cover the entire wing leading edge, while on the older versions they start just outside the wing fences.
Replace the General Electric CF700 engines by Garrett ATF3s and you get the Falcon 20G. These engines can be recognised by a large plug back of the engine.
Most of the Falcon 20Gs were delivered to the US Coast Guard as HU-25, described separately below.
The first and original version of the Guardian has the same external appearance as the Falcon 20G.
The HU-25B was the pollution control version for the US Coast Guard. It was equipped with a side-looking airborne radar (SLAR) under the right forward fuselage. All were converted HU-25As.
HU-25C & HU-25C+ Guardian
To make room for a new search radar the nose had to be enlarged a bit. Therefore the HU-25C has a slightly more pointed nose than the other HU-25 models. Also it has a FLIR pod under the forward fuselage. Behind it is a streamline body.
The HU-25C+ has an improved radar and FLIR, but we have not found any external differences compared to the HU-25C.
The final subtype, the HU-25D, has the same FLIR pod as the HU-25C+, but a normal nose shape around a new radar.
Falcon 20C-5, D-5, E-5, F-5 & Falcon 20-5
The CF700 engines produce quite some noise, so Dassault developed a re-engine programme. In the beginning, TFE731- 5AR engines were used and the Falcon 20s that are equipped with this version received “-5” after the type designation. Later, and even now, the TFE731-5BR is utilised. Falcon 20s with-5BR engines are simply known as Falcon 20-5. In general, you can recognise Falcon 20s equipped with the new engines by the larger diameter engine nacelles, without the “tab” at the back. Of course, in addition the previously mentioned differences apply. But a Falcon 20-5 cannot be distinguished from a Falcon 20C-5/D-5/E-5/F-5.
The Falcon 200 has ATF3 engines like the Falcon 20G, but also has a shorter dorsal fin with an air inlet. The original designa- tion of the subtype was Falcon 20H.
Confusion possible with
Especially when you only see the front of the aircraft you might mistake a Falcon 50 for a Falcon 20. The forward fuselage is essentially the same. However, in normal cases the third, centre engine is an easy recognition point.
The Hawker family is the most similar aircraft to the Dassault Falcon 20 series. It also has a cruciform tail, but horizontal stabiliser is mounted higher, about a third from the top. Also the cabin windows are rectangular, the cockpit windows are different, next to a lot more differences.
The Falcon 10 is clearly derived from the larger Falcon 20. The Falcon 10 is shorter with three or four cabin windows, has different cockpit windows and one wheel on the nose landing gear.
