50-867: Intended to replace the Dassault HU-25 Guardian jet, the HC-144A Ocean Sentry is part of the Coast Guard's Integrated Deepwater System Program of recapitalization and new-asset acquisition. Based on the CN-235-300 MP Persuader , the maritime patrol version of the CN-235 military transport, the HC-144 offers a longer endurance than the HU-25 it is replacing in U.S. Coast Guard service, as well as better performance in

100-573: A 36-plane fleet. Cancelling the remaining 18 to be manufactured and replacing them with up to 14 decommissioned C-27Js would save between $ 500–$ 800 million. Converting the Spartans to search-and-rescue aircraft would be faster and cheaper than funding and delivery of the full order. EADS responded by stating that the HC-144 is half as expensive to maintain and operate compared to the C-27J in terms of direct maintenance and fuel costs, calling into question

150-580: A Falcon 20 had the distinction of becoming the first civilian jet to fly on 100% biofuel . During the 1950s and 1960s, the French government, which had taken a significant interest in the re-establishment and growth of its national aviation industries in the aftermath of the Second World War , developed a detailed request for a combined liaison / trainer aircraft, to be equipped with twin-turbofan engines. Among those companies that took interest in

200-409: A consequence of rapidly increasing demands, it was recognised around this point that the introduction of larger cargo aircraft to supplement the type would soon be necessary in order to expand. At the height of its use of the type, Federal Express operated a fleet of 33 Falcon 20; the type was eventually withdrawn following is gradual replacement by substantially larger aircraft, the first of these being

250-642: A distance of 1000 km. Deliveries of the type soon commenced to Pan American's outfitting facility at Burbank Airport , California . All non-American aircraft were fitted out prior to delivery at Bordeaux-Merignac . During 1966, the company redesignated the American-delivered aircraft as the Fan Jet Falcon ; this was subsequently shortened to the Falcon 20 . During 1967, Pan Am Business Jets Division decided to increase their firm orders for

300-476: A further 120. On 10 July 1964, the re-engined aircraft made its first flight. On 1 January 1965, the first production aircraft performed its maiden flight; in June 1965, both French and American type certifications were awarded. On 10 June 1965, French aviator Jacqueline Auriol achieved the women's world speed record using the first Mystère 20 prototype, having flown at an average recorded speed of 859 km/h over

350-465: A result of an early distributor arrangement with American airline Pan American (Pan Am), American-delivered aircraft were marketed under the name Fan Jet Falcon ; it soon became popularly known as the Falcon 20 . American orders proved valuable early on; by 1968, Pan Am Business Jets Division had placed orders for 160 Falcon 20s. Further major orders were soon placed for the type by several operators, both civil and military; amongst others, these included

600-443: Is the aircraft's 'throttle-lock' power management system to maintain safe levels of engine power throughout climbs without any crew commands. As conventional thrust reversers are not compatible with the location of the engines, an alternative configuration in the form of rotatable doors fixed to the outer cowling of the engine partially cover both the engine fan and core exhaust, deflecting thrust upwards and forwards. The Falcon 20

650-701: The Boeing 727-100 . The Falcon 20 which had carried the first Federal Express air express package has since been placed on static display at the Smithsonian 's Udvar-Hazy Center at Dulles Airport . The United States Coast Guard (USCG) operated a model of the Falcon 20, designated as the HU-25 Guardian. The Guardian was operated as a high-speed spotter aircraft to locate shipwreck survivors and direct slower-moving aircraft and rescue vessels, and to interdict aerial and shipborne drug trafficking . In 1982,

700-778: The French Navy , the United States Coast Guard , and Federal Express . An improved model of the aircraft, designated the Falcon 200 , was developed. This variant, powered by a pair of Garrett ATF3 engines, featured several major improvements to increase its range, capacity, and comfort. Additionally, a number of Falcon 20s that had been originally powered by the CF700 engines were later re-engined with Garrett TFE731 turbofan engines. The aircraft proved to be so popular that production did not end until 1988, when it had been superseded by more advanced developments of

The Dassault Falcon 20 is a French business jet, often considered to be an easy to fly and relatively visually appealing aircraft. The favourable flight qualities of

800-553: The 1991 Gulf War . Initial models of the HU-25 were delivered to the HU-25A standard; a number were later modified to become HU-25Bs, which were equipped with sensors capable of detecting oil spills and other environmental pollutants. Further numbers were re-configured to the HU-25C standard, for improved performance in the drug interdiction mission; when equipped with newer AN/APG-66(V)2 and AN/APS-143B(V)3 radar systems, these became

850-433: The Coast Guard celebrated the crafts' 100,000th hour of operation in service. The Coast Guard is only the third aircraft operator to reach 100,000 hours on this type aircraft, and the fastest to do so (only 8 years). Estimates are the type will reach 200,000 hours in Coast Guard service by 2022. The Coast Guard is upgrading its 18 HC-144As to HC-144Bs intending to improve mission effectiveness and situational awareness through

900-411: The Coast Guard's fleet of 17 HC-144s reached 50,000 flight hours, five years after achieving IOC. The Ocean Sentry is flown more hours per airframe in a year than any other Coast Guard aircraft. The 15th HC-144 was delivered in June 2013. The Coast Guard was considering supplementing the HC-144 with former Air Force C-27J Spartan aircraft. Budget strains have caused the service to reconsider acquiring

950-648: The Falcon 200 model had the largest cabin of any mid-size business jet. Additionally, the rear fuselage of the Falcon 200 was re-designed to accommodate a 28-cubic foot baggage compartment within the tailcone, which supplements the standard aft cabin baggage compartment. While sales in the North American market was initially strong, sales were negatively impacted by the Recession of 1969–70 , which led to excess unsold Falcon 20 aircraft temporarily building up while Pan American Business Jets Division sought sales of

1000-446: The Falcon 200 model, the wing was re-profiled for improved low-speed performance and shortened runway requirements, as well as the addition of an unusual wing root fillet section and a shortened wing fence ; the development of an entirely new wing was under consideration at one point, but the improved performance was not viewed to justify the expense. While air brakes are present upon the wing, these are less smooth and more noisy than

1050-420: The Falcon 20G and HU-25 models, were powered by a pair of Garrett ATF3 engines. According to the magazine Flying , the Falcon 200 variant was more comparable to the newer Falcon 50 trijet than the original Falcon 20 model. Due to its popularity, Dassault studied and worked upon various variants and extensive derivatives of the Falcon 20. Later-built developments of the type include the smaller Falcon 10 ;

1100-408: The Falcon family. Due to the increasing implementation of noise-abatement regulations, the Falcon 20 has either been subject to restrictions on its use in some nations, or been retrofitted with Stage 3 noise-compliant engines or hush kits upon its non-compliant engines. The type has also been used as a flying test bed and aerial laboratory by a number of operators, including NASA . In November 2012,

1150-522: The Fan Jet Falcon, Fan Jet Falcon Series D and Fan Jet Falcon Series E. This modification has been commonly used upon those Falcon 20s which have been operated as special mission aircraft, which would often make use of underwing stores. Substantial numbers of Falcon 20s were converted into cargo-carrying configurations; a hydraulically -operated cargo door served to simplify loading-unloading operations. According to Flying Magazine, upon its launch,

1200-507: The Garrett TFE731 and ATF3 engines. The adoption of newer engines often had the benefit of improving the Falcon 20's range in addition to increased speed and climb rate; this, in combination with its low-drag fuselage, required more careful speed planning than the majority of business jets. On some models, protection against engine conditions such as instances of over-speed and over-heating is provided by electronic flight computers, as

1250-610: The HU-25C+ and HU-25D respectively. On 26 September 2014, following 32 years of service, the last operational HU-25 Falcon, the only jet ever to be a part of the air fleet of the US Coast Guard, was retired. The high-speed capability it provided will be lost with the type's retirement due to its replacements being considerably slower aircraft. In 1988 the United States Coast Guard tested a Falcon 20C (tail-number N200GT) using Garrett TFE1042 afterburners . This required adding

On 4 May 1963, the Mystère 20 prototype, registered F-WLKB , conducted its maiden flight from Bordeaux–Mérignac Airport , Gironde , France. By this stage, attention in the programme was centered around

1400-480: The aircraft meant that no need existed to incorporate a stick pusher or stall-barrier systems to achieve its predictable stall behaviour. The flight controls of the Falcon 20 are hydraulically powered, augmenting the mechanical pushrods between the cockpit controls and the flight control surfaces . In the event of complete hydraulic failure, the aircraft can be practically flown without any augmentation. The controls incorporate an artificial feel system , optimising

1450-399: The aircraft was issued during December 1961. It is a low-wing monoplane design, powered by a pair of rear-mounted General Electric CF700 turbofan engines. On 4 May 1963, the prototype made its maiden flight. The first production aircraft was introduced on 3 June 1965. On 10 June 1965, French aviator Jacqueline Auriol achieved the women's world speed record using the first prototype. As

1500-658: The aircraft's systems upon installation. The HC-144A's equipment is similar to the Coast Guard's HC-130 aircraft, which reduces maintenance and training costs. The first HC-144 was delivered to the U.S. Coast Guard in December 2006. Initial Operational Capability (IOC) was achieved in April 2009; thirteen Ocean Sentry aircraft were operational with the Coast Guard in January 2011. A total of 36 aircraft were planned to be procured, with twelve Mission System Pallets being swapped between

1550-403: The commercial opportunities for the type, particularly the large North American market. According to aerospace publication Flying , while Dassault had achieved satisfactory technical progress on the Mystère 20, it was recognised even by the company's officials that the firm lacked both the sales presence and the experience to effectively market the type to English-speaking nations. Accordingly,

1600-621: The end of the type's production. During 2013, the FAA modified 14 CFR part 91 rules to prohibit the operation of jets weighing 75,000 pounds or less that were not Stage 3 noise compliant after 31 December 2015. The Falcon 20 was listed explicitly in Federal Register 78 FR 39576 . Any examples of the type that had not been modified, either by the installation of Stage 3 noise-compliant engines or have had hush kits installed upon noncompliant engines, were no longer permitted to fly anywhere in

1650-536: The first HU-25 was delivered to the USCG; by December 1983, a total of 41 aircraft had been acquired. In USCG service, the HU-25 was eventually succeeded in its role by the EADS HC-144 Ocean Sentry , a newer turboprop -powered aircraft. Operationally, the HU-25 played a key role in the service's actitives in search and rescue, counter drug missions; it had also been a critical asset deployed during

1700-428: The government request was French aircraft manufacturer Dassault Aviation . In December 1961, French aircraft designer and head of Dassault Aviation, Marcel Dassault , gave the go-ahead to proceed with work towards the production of an eight- to 10-seat executive jet /military liaison aircraft, which was initially named as the Dassault-Breguet Mystère 20 . The emerging design was of a low-wing monoplane, which drew upon

1750-479: The idea as a cost-saving measure. With the signing of the U.S. Defense Authorization Bill for Fiscal Year 2014 on 26 December 2013, the Coast Guard was given control of the 14 remaining C-27Js available. The 16th HC-144 was delivered on 22 January 2014, the 17th on 7 April 2014, and the 18th and final HC-144A was delivered on 7 October 2014. On 22 September 2017, a ceremony was held in Mobile, Alabama where Airbus and

1800-429: The larger 30-seat Falcon 30 with a larger fuselage cross section, which was built and test flown, but did not proceed to production; and the Falcon 50 , an improved three-engined development. The Falcon 20 proved to be so popular that production was not terminated until 1988, when it had been superseded by more advanced developments of the Falcon family. A total of 473 Falcon 20s and 35 Falcon 200s had been constructed by

1850-589: The latter factor lending itself well to cargo operations. Despite difficulties securing the necessary finances, the fledgling company was able to acquire several Falcon 20s and convert them for cargo operations. Originally, Federal Express intended for its Falcon 20s to be delivered post-conversion, as a consequence of funding issues, the aircraft were acquired in handfuls and independently converted from their initial passenger-carrying configuration to support their use for cargo operations. In September 1972, Federal Express established an in-house training school, focused on

Its rear ramp provides for transport of standard cargo pallets. It also features short takeoff and landing capability. The HC-144A uses electronic systems on the Mission System Pallet roll-on, roll-off electronics suite from Lockheed Martin , that connects to

1950-475: The market, which was marketed as the Dassault Falcon 10 . During the late 1950s and early 1970s, aviation businessman Frederick W. Smith was seeking an ideal aircraft with which to launch his new business, Federal Express ; Smith soon identified the Falcon 20 as showing promise for his purposes, noting the availability of unsold aircraft due to an economic downturn and its atypically strong fuselage,

2000-545: The operational aircraft. The HC-144A has been involved in several missions during its career, including involvement in the Marquis Cooper search-and-rescue mission, the response to the 2010 Haiti earthquake , environmental missions monitoring the Deepwater Horizon oil spill , transporting endangered marine animals for rehabilitation, and being involved with Hurricane Sandy relief efforts. In June 2014,

2050-446: The option of directly selling the type was discarded in favour of seeking an established US distributor. Coincidentally, management at Pan Am happened to be seeking a suitable aircraft to launch its planned corporate jet aircraft sales division, and following a review of a range of available business jets of the era, took an interest in the Mystère 20. Progress between Dassault and Pan Am was rapid, moving from engineering evaluations of

During November 2012, a Falcon 20 became the first civil jet in the world to fly on 100 per cent biofuel when it performed

2250-430: The sensations perceivable to the operating pilot to be smooth, predictable, and precise. On the Falcon 200, the cockpit is heavily modernised, being more comparable with the newer Falcon 50 than the original Falcon 20. The Falcon 20 is powered by a pair of rear-mounted turbofan engines; most commonly powered by a pair of General Electric CF700 engines, the type has also been powered by alternative powerplants, including

2300-664: The type to 160 Falcon 20s. Military orders for the type were quickly received from Australia, the U.S., and Canada, in addition those placed by France. In 1973, FedEx's Falcons, designation FA-20-DC, cost $ 1.2 million each and were modified with a 55-by-74.5-inch forward cargo door with independent power supply, higher mtow, reinforced floor, plugged windows, and bigger brakes. A number of Falcon 20s that had been originally powered by CF700 engines were later re-engined with Garrett TFE731 engines under AMD-BA Service Bulletin No. 731. To distinguish these re-engined aircraft from those still using

2350-430: The type to the formation of general agreements between the two companies. In response to feedback received from Pan American, the aircraft was re-engined with a pair of General Electric CF700 engines and several dimensions were increased. Accordingly, Pan American formed an agreement with Dassault to distribute the Mystère 20 in the western hemisphere; the firm placed an initial order for 40 aircraft along with options for

2400-482: The type. By late 1973, American sales had recovered while responsibility for sales had been transferred to the Falcon Jet Corporation, an organisation jointly staffed by Pan American and Dassault personnel in which Dassault became the pre-dominant partner in the venture. Additionally, by this point, Dassault were already preparing for the launch of a smaller and improved derivative of the aircraft onto
