Falcon 20G Guardian

Development of a light twin-turbojet executive transport was initiated by Dassault in conjunction with Aerospatiale (then Sud-Aviation), with construction of the prototype starting in January 1962. A cantilever low-wing monoplane with swept wings and tail surfaces, a circular-section fuselage and retractable tricycle landing gear, the prototype had a fuselage built by Dassault and wings and tail unit by Sud-Aviation. However, for production aircraft Dassault builds the wings and Aerospatiale the fuselages and tail units.

First flown on 4 May 1963, and at the time powered by two 1497kg thrust Pratt & Whitney JTF12A-8 turbo-jets pod-mounted one on each side of the rear fuselage, the new aircraft was identified as the Dassault Mystere-Falcon 20 (Mystere in France, and Falcon for export sales). It was re-engined subsequently with General Electric CF700 turbofans, which became the standard powerplant. Following certification the Business Jets Division of Pan American World Airways (now known as Falcon Jet Corporation) became interested in this aircraft for sale in North America, where they were marketed under the name Fan Jet Falcon.The Mystere-Falcon 20 found employment for both civil and military use with orders approaching 500.

The first production aircraft made its maiden flight on 1 January 1965 and this initial series became identified as the Standard Falcon 20. From this was developed a version with increased fuel capacity, available as the Falcon 20C with the same 1871kg thrust General Electric CF700-2C powerplant as the Standard Falcon, or as the Falcon 20D with the more powerful CF700-2D with a thrust rating of 1928kg. The introduction of 2041kg thrust CF700-2D-2 engines resulted in a version designated Falcon 20E, and the addition of high-lift devices to improve take-off and landing performance and a further increase in fuel capacity were identifying features of the Falcon 20F.

Development of an improved Falcon 20G was initiated and this was offered by Falcon Jet Corporation to meet a US Coast Guard requirement for a medium-range surveillance aircraft. A contract for 41 aircraft, designated HU-25 Guardian, was awarded in 1977. Basically similar to the Falcon 20F, they differed in having airframe modifications required to accommodate varying role equipment, plus the installation of 2512kg thrust Garrett ATF 3-6-2C turbofan engines. In USCG service the HU-25A is used in the search and rescue role, HU-25B is the pollution control version, and the FLIR-equipped HU-25C modified for the drug interdiction role using a Westinghouse APG-66 search radar.

Most recent development is the Falcon 200 which replaced the Falcon 20F on the production line in 1983, after 473 Falcon 20s had been delivered. Originally designated Falcon 20H the prototype 200, fitted with less powerful 2360kg thrust ATF 3-6A-4C engines, bigger fuel tanks in the rear fuselage, some systems' changes and redesigned wingroot fairings, flew for the first time on 30 April 1980. Announced at the 1981 Paris Air Salon the Falcon 200 was certificated by the DGAC on 21 June 1981 and deliveries began in 1982. By 1989 35 had been delivered to 11 countries. The maritime patrol and enforcement version of the Falcon 200 is marketed as the Gardian 2, and has a Thomson-CSF Varan search radar, two Exocet sea-skimming air to surface missiles mounted on underwing pylons, electronic surveillance and countermeasures equipment and target-towing capability. Five are in service with the French navy.

I spent 12 yrs in this A /C a standard C model with the later 2D2 engines.
Ni-cad battery's were problems due to poor cell quality.
the earlier Ge 700's had discharge module problems, compressor fan blade's tip clearances (compressor) stalls. operation damages, due to wind parking,ground, Deer on runways wing flap damages, the electrical sys. was very good. parts & repairs were also very good.
I also flew several other jets. The old falcon was the best.

Even with its short commmings of range and speed, by today's standards, for a first generation corporate jet it was no slouch. I put nearly 5000 hrs in Falcon 20's, mostly in a "c" model with upgraded GE 2D-2's. It was one of the best handling, most dependable airplanes that I ever had the pleasure of flying. Most importantly the boss and his guests loved with cabin.

I bought #99 from the Business Jet Division of Pan Am World Airways in the top of the Pan Am Building in the Summer of 1967. It is sitting in the hangar at the airport right now.

I flew the Falcon 20 with the GE engines for Conoco Oil Company in the early 80's. The aircraft was built like a tank and very reliable. The Falcon was comfortable with an APU and was easy to fly. The cruise speed was a little slow at .74 mach and the range was only about 3 hours 30 mins. The fuselage had no time limit and was vitually certifified to fly forever.

I flew the first Falcon 20 Pan Am brought into the US. it was N801F with no thrust reversers or APU. This aircraft was sleek and beautiful fun to fly and needed long runways.
Pan Am did a great job marketing the Falcon and plaaced it in the must have business jet of its day.

I weld wire model aircraft sculptures. I have made many Falcon 20 models for pilots and employees of Federal Express. The models are 'desktop' size and cost about $125.00. Shipping is extra but doesn't amount to much. Send an email to me and I will respond to you with some interesting information.
Thanks - Mike

I flew the Falcon 20 in the Electronics Warfare role in the Canadian Air Force.
Since our job required "fighter tactics" we flew it that way -and found that it did as nice a roll as a CF104 or CF5 ever did -and since our "passengers" were experienced navigators they ate it right up.

The Falcon 20 -and its younger sister the Falcon 10 were both sportscars. I always felt at home in the cockpit -it "felt" like a fighter -as I imagne a Mosquito must have felt -and its performance was equivalent!

i want to have informatios about these points:
*what about all socities in arbic contries.
*what are the curent mecanique troublshooting concuring the hydraulic sys of the plane.
