Dassault Falcon 7X

The Dassault Falcon 7X is a large-cabin, range business jet manufactured by Dassault Aviation, the second largest of its Dassault Falcon line. Launched at 2001 Paris Air Show, its first flight was on 5 May 2005 and it entered service on 15 June 2007. The Falcon 8X is derived from the 7X with a longer range of afforded by engine optimizing, aerodynamic refinements and an increase in fuel capacity. Featuring an S-duct central engine, it and the Falcon 900 are the only two trijets in production.

Falcon 7X

Development

Dassault launched the FNX at the 2001 Paris Air Show, aiming for a 10,500km (5,700nm) range at Mach 0.88, up from the Falcon 900EX's 8,300 km at Mach 0.84. Its new high-speed wing is longer with 5° higher wing sweep than the 900 wing; while its fuselage is 20% longer, it keeps the same cabin cross-section but with a new curved windscreen. The trijet has a combined thrust of 18,000lb (80kN) provided by Honeywell FX5s, a new design, or a Pratt & Whitney Canada PW306 growth version. Based on Honeywell Primus Epic avionics, its EASy cockpit is developed for the Falcon 2000EX and 900EX and controls are fly-by-wire. Scheduled to fly in 2004, first deliveries were planned for mid-2006.

With 41 deposits, it was named 7X in November with first flight slipping from late 2004 to early 2005 and certification planned for mid-2006. With a simplified structure to reduce cost and weight, the optimised high-transonic wing improves the lift-to-drag ratio by 10% over the supercritical wing of the Falcon 50 shared by previous Falcons. The cabin is 2.4m (8ft) longer than the 900 and has a lower 6,000ft (1,800m) cabin altitude. the PW307A was finally selected, among other risk-sharing partners: Honeywell for avionics architecture, auxiliary power unit, air management system; with Parker Hannifin for the power generation system and wheels brakes; and TRW Aeronautical Systems for the hydromechanical flap and airbrake systems.

With over 50 firm orders, it completed its first flight on 5 May 2005, flying for 1h 36min from Bordeaux-Merignac, starting a 1,200h flight test programme over 15 month: it climbed to 10,000 ft (3,000 m) for hydraulic, fuel, air data and landing gear extraction/retraction systems tests, then climbed to 25,000 ft for acceleration/deceleration tests and basic autopilot and autothrottle operations. The second Falcon 7X was planned to join in June of that year, and the third with a full interior in September that year for long-range, endurance tests and interior sound level validation: Dassault aims for a 52dB sound level in the cabin, 4dB lower than other Falcons. Certification slipped to late 2006 and first deliveries to early 2007.

It was first presented to the public at the 2005 Paris Air Show. The aircraft has received its type certification from both the Federal Aviation Administration and European Aviation Safety Agency (EASA) on 27 April 2007. The first 7X, MSN05, entered service on 15 June 2007. The hundredth was delivered in November 2010. It conducted high altitude airport tests at in Daocheng in 2014.

Price

In 2001, the Falcon 7X, at approximately $35 million (preproduction order price), was nearly $10 million cheaper than its nearest competitors in the long-range, large cabin market segment, including the Gulfstream G550 and Bombardier Global Express. It was targeted to be priced for 2004 at 12% more than the $33 million top-of-the-range Falcon 900EX equipped: $ million. Its price was $37 million in 2005, and $41 million in 2007.
In 2017, its list price was $54M, a 3-4-year-old 7X was worth $27-34m and a 7-9 year old one cost $19-24M. The latest market data for Q1 2020 shows 287 out of 289 aircraft currently in operation with an asking price range of $18,495,000 - $24,800,000.
In 2022, its equipped price was $53.8M.

Design

The Falcon 7X is a three-engined cantilever monoplane with a low-positioned, highly swept wing. It has a horizontal stabiliser at mid-height and a retractable tricycle landing gear, and three rear-mounted Pratt & Whitney PW307A turbofan engines : two on the side of the fuselage and one in a center position, and room for 19 passengers and 3 crew. It is the first production Falcon jet with winglets.

It is the first fully fly-by-wire business jet and is equipped with the same avionics suite, the Honeywell Primus Epic " Enhanced Avionics System" (EASy), that was used on the Falcon 900EX and later on the Falcon 2000EX.

The Falcon 7X is notable for its extensive use of computer-aided design, the manufacturer claiming it to be the "first aircraft to be designed entirely on a virtual platform", using Dassault Systemes' CATIA and PLM products.

In February 2010, Dassault Falcon and BMW Designworks were awarded the 2009 Good Design Award by the Chicago Athenaeum and the European Centre for Architecture Art Design for their collaboration on the new Falcon 7X interior option.
Due to special engine mounts and cabin isolators, the cabin is extremely quiet, below 50 dBA, and is available with a shower.

Pitch trim incident

EASA grounded the Falcon 7X fleet after a report from Dassault Aviation regarding an uncontrolled pitch trim runaway during descent in one of its jets in May 2011. The aircraft pitched up to 41 degrees, with the load factor increasing to 4.6''g'', it climbed from 13,000 to 22,500 ft and the airspeed went from 300 to 125 kn.

"This condition, if occurring again, could lead to loss of control of the aeroplane," the EASA notice said. Initial results of investigation showed that there was a production defect in the Horizontal Stabilizer Electronic Control Unit which could have contributed to the cause of the event. Dassault Aviation developed modifications in June 2011 to allow a return to flight.

After four years of investigation, the Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile published its final report in June 2016. It was found that incorrect nose-up commands to the trimmable horizontal stabilizer were caused by a soldering defect on the pin of its electronic control unit provided by Rockwell Collins.

Teterboro-London City record

On May 2, 2014, Dassault Falcon pilots Philippe Deleume and Olivier Froment set a new speed record for the Falcon 7X on a 5 h 54 min flight from New York Teterboro Airport with three passengers on board.

Falcon 8X

The 6,450 nmi (11,945 km) range Falcon 8X was announced at the European Business Aviation Convention & Exhibition in May 2014. Its cabin is longer than the 7X. With improvements to wing design and improved Pratt & Whitney Canada PW300, the 8X is up to 35% more fuel efficient than its competitors.

The prototype, registered F-WWQA, first flew from Bordeaux–Mérignac Airport on 6 February 2015. The Falcon 8X was added as a subtype of the Falcon 7X on the EASA type certificate on 24 June 2016 as modification M1000 for S/N 0401 and ongoing. Dassault delivered the first Falcon 8X on 5 October 2016 to Greek business aviation operator Amjet Executive.
By October 2018, the Falcon 8X FalconEye EFVS was approved by the FAA and EASA for approaches down to , and dual HUD FalconEye will allow EVS-to-land in 2020, without using natural vision.

The three PW307D turbofans gained each, and are 1.5% more fuel efficient.
MTOW is increased from and fuel capacity is increased by for more range.
The wing structure is lighter, and more flexible for comfort, while operating empty weight is heavier than the 7X despite the stretch.
A strict weight control allows most operators to match or best Dassault's estimate BOWs for a fully equipped aircraft with three crewmembers.
Its unmatched structural efficiency, with a OEW only half of MTOW, allow a superior fuel efficiency while its MTOW is less than a Gulfstream IV-SP.
The first hour fuel burn is while average cruise fuel burn is per h.
The 47 db average cabin sound level is 2-3 db lower than the Falcon 7X.
In 2022, its equipped price was $62.5M.
