Falcon 900: how it differs from its rivals

On the pre-owned market the Falcon 900 sits in the same budget as the Bombardier Challenger 604 and 650, the Embraer Legacy 600/650 and the Gulfstream G450. One class, a similar number of seats, money that overlaps. I go through four places where the Falcon 900 parts company with its neighbours on confirmed figures: three engines, ceiling, cabin height and takeoff weight. Separately I show where those differences cost the owner money.

Five aircraft on confirmed figures

The specifications are book figures for the types, taken from the model cards and the catalogue. Prices are market reference points for August 2026, to my information. The value of a particular aircraft is calculated from its records, its hours and its specification.

A note on the table. The cabin dimensions of the G450 are missing from my database, so the cell is empty: for the type I have the aircraft length and a three-zone layout confirmed, the cabin dimensions are absent from the sources.

Full specifications are on the Falcon 900 model card. The neighbours in this comparison: Challenger 604, Challenger 650, Legacy 600/650, G350/G450.

Three engines: what they give

The Falcon 900 carries three Honeywell TFE731 engines in the tail. Every neighbour in the table is a twin.

The practical sense of the third engine lies in two places. The first is ocean routes: the margin of reliability lifts part of the restrictions a twin plans its flight under. The second is short and high-elevation runways: thrust on takeoff is higher, and the route network gains airfields.

Composites in the airframe hold the weight down: 20,640 kg on the Falcon 900B against 21,863 kg on the Challenger and 24,300 kg on the Legacy 650. The three engines add a third set of maintenance work and a third remaining life into the calculation of the deal. The owner sees this in the first-year budget, the buyer sees it in the price.

Ceiling: three kilometres of difference

15,500 m on the Falcon 900 against 12,000–12,497 m on the Challenger and the Legacy. The difference is tangible: three and a half kilometres of altitude.

The upper levels are freer of traffic, and most weather fronts stay below. In practice this means a direct route where aircraft with a 12,000 m ceiling go around, and less turbulence on a long leg. Of the five the G450 comes closest at 13,716 m; the other three stay at their own level.

Cabin: height against width

The Falcon 900 shares its fuselage cross-section with the Falcon 2000 and the Falcon 7X: 2.34 m wide, 1.88 m high. The Challenger is seven centimetres wider and five lower. The Legacy 650 is six centimetres lower and twenty-four narrower.

A height of 1.88 m means walking the aisle upright for someone 185 cm tall. On an eight-hour leg this is felt far more than seven centimetres of width: the aisle is walked dozens of times a flight, the shoulders of the seats are touched rarely.

Length plays for the Legacy. A 12.9 m cabin divides into three zones with room to spare, while the Challenger 604 has a cabin around 8.7 m long. The Falcon 900 also lays out in three zones — a club section, a conference area and a rest area with a divan.

Takeoff weight and airport charges

20,640 kg against 33,838 kg on the G450 — a difference of thirteen tonnes.

Airport charges at many hubs are calculated from maximum takeoff weight. On a regular network of expensive European airfields that difference adds up over a year to a sum comparable with the cost of the calendar checks. The range meanwhile differs by 744 km in the Falcon 900's favour.

Inside the Falcon pair the difference lies in another place. The Falcon 2000LXS, with a landing distance of 689 m and a takeoff weight of 19,414 kg, solves the short-runway task at ten passengers and a range of 7,408 km. The Falcon 900 adds four seats and fifteen hundred kilometres of range to the same cabin cross-section. The details are on the Falcon 2000 model card.

Money: the entry point and the depth of the market

The entry point on the pre-owned market differs several times over. The bottom of the Falcon 900 family is $8.8 million: listings for the 900EX at $8.95–9.9 million fall into that corridor. Above them the 900EX EASy sits around $15.95 million, and the 900LX by the Aircraft Bluebook of summer 2024 falls between $18.5 and $45 million depending on the year. A new 900LX on the 2023 list price is $44.7 million. All the figures are to my information.

The Challenger 604 at a median around $6 million gives the cheapest entry into the class, to my information. The Legacy 600 starts at $3.5 million, and that is the most accessible point among the five. Behind a low price of entry comes the cost of keeping the aircraft, and among machines of one class that differs less than the purchase price does.

The Falcon 900 has been in production for more than forty years, over 500 aircraft have been built, and the current 900LX stands on the line. Factory support and parts for the type work in full. The Legacy 600/650 left production in 2020 after 289 aircraft, the Challenger 604 closed in 2006, the G450 in 2018. Of the neighbours in the table the Challenger 650 remains in production.

Who it suits

Falcon 900 — regular legs of seven to nine hours with a group on board, a route network with short and high-elevation airfields, ocean sectors. From 300 hours a year.

Challenger 604 — the same seven or eight passengers on routes up to eight hours with the lowest entry budget. Cabin width greater by seven centimetres, ceiling lower by three kilometres.

Legacy 650 — a long three-zone cabin and thirteen to fourteen passengers on legs up to 7,200 km. The engineering, the layouts and the versions are on the Legacy 600/650 model card.

G450 — sixteen seats and a range of 8,056 km, if takeoff weight in your network of airports is uncritical.

At a hundred hours a year and routes up to three hours any of the five carries air: the fixed part of the costs stays where it is, the capability of the airframe goes unused.

What to check on a particular aircraft

The version in the records. A Falcon 900B presented as a 900EX, and a 900DX under the 900LX name, are an ordinary story on the pre-owned market. The difference between versions runs to fifteen hundred kilometres of range and to several million dollars in price.

Engines. On the Falcon 900 there are three, and the time remaining to the next removal is counted on each one separately. The status of the hourly cost programmes passes to the new owner and counts as an asset in the deal.

Avionics. Aircraft predating the EASy flight deck need upgrading to meet current communication and surveillance requirements: money and weeks on the ground.

Cabin. The year of the last interior refurbishment. Work on the cabin of a large aircraft costs as much as a good light jet.

Records. Gaps in the entries, service bulletins left undone, components without confirmed provenance. Every position converts into a discount off the price, or into the first-year budget of ownership.

Conclusion

The Falcon 900 takes ceiling, range, cabin height and low takeoff weight. The Challenger answers with cabin width and the cheapest entry into the class. The Legacy 650 answers with cabin length and the number of seats. The G450 answers with capacity, and pays for it in thirteen extra tonnes of takeoff weight.

Beyond that the particular aircraft decides: the time remaining on the three engines, the status of the maintenance programmes, airframe hours and cycles, the avionics fit and the condition of the records.

The figures in this article are reference points; the specifics are calculated for the particular aircraft. The neighbouring review of the ultra-long-range class is in the Falcon 7X specifications, and the method of comparing types is in the article on the G550 against the Global 6000 and the Falcon 7X.
