The Cessna model 700 ‘Citation Longitude’ is a super-midsize jet developed and manufactured by Textron Aviation of the USA.

Textron Aviation originally announced the development of the Citation Longitude in 2012, and the aircraft first flew in October 2016. Some three years later, in late 2019, the Citation Longitude was delivered to its first customer.

The Cessna Citation Longitude shares the same cabin width and flat-floor cabin as the smaller Citation Latitude. However, the Longitude features an extended cabin, a longer transatlantic range, and external differences, including blended winglets and a T-tail design.

The Gulfstream G280 is a super midsize jet developed by Gulfstream Aerospace and manufactured by Israel Aerospace Industries (IAI).

Initially designated the name Gulfstream G250, its first flight was in 2009 before the project was later renamed to the G280. Developed as a follow-on aircraft to the Gulfstream G200, the newer G280 featured many design improvements including a larger cabin, new glass cockpit and a larger wing design derived from the Gulfstream G550 ultra-long-range jet.

Unlike other members of the Gulfstream family, the G280 is manufactured in Israel by IAI. The airframes are then flown to Gulfstream’s facility in Dallas in the United States for interior completion and painting.

To date, more than 200 Gulfstream G280s have been manufactured and delivered worldwide.

The Embraer Praetor 500 and 600 are midsize jets developed and manufactured by Embraer. Developed from the highly successful Legacy 450 and 500 models, the Praetor 500 and 600 incorporate a number of design and performance modifications making an already highly advanced family of aircraft even greater game changers.

Announced in 2018, the Praetor 500 and 600 feature 22 inch taller inch winglets for greater fuel efficiency, and larger ventral fuel tanks to substantially increase range.

Powered by two Honeywell HTF7500E turbofan engines, the Embraer Praetor 500 and 600 boast maximum ranges of 3,250 and 3,900 nautical miles respectively, bringing city pairs such as London to Dubai, New York to London and Beijing to Singapore within reach.

The Embraer Legacy and 500 is a super midsize jet developed and manufactured by Brazilian manufacturer Embraer. Along with the smaller Legacy 450, the Legacy 500 was initially announced in 2007 as concept aircraft to fill a market gap between Embraer’s Phenom 300 light jet and their Legacy 600/650 heavy jets.

Development on the Legacy 450 and 500 program commenced in early 2008 with introduction of both models planned for between 2012 and 2013.

Cited by many as the world’s most advanced private aircraft, the Legacy 450 and 500 share many common design features with the greatest difference being the fuselage length increase of 4 feet (122 inches) on the Legacy 500. Both Legacy 450 and 500 models feature a flat floor stand-up cabin with typical cabin capacities for seven and eight passengers respectively.

Powered by two Honeywell HTF7500E turbofan engines, the 500 has great short field performance, allowing access to more airports worldwide. Its short field capabilities allowed the smaller Embraer Legacy 450 to become the first midsize jet to be approved to operate into La Mole Airport, St. Tropez after meeting strict performance requirements demonstrated during flight tests conducted in April 2016.

The Cessna 750 Citation X and Citation X+ are super midsize jets developed and manufactured by Cessna in the USA. First delivered in 1996, the Citation X assembly line operated for 22 years with the final airframe being delivered in 2018, with a total number manufactured of over 320.

Unlike earlier Citation models, the Citation X was not based on earlier designs. Instead, the model 750 was an entirely new design with the intention of taking over the previous Cessna 650 family. The primary design objective with the Citation X was a super midsize jet of unrivalled speed, something which is easily identifiable by the aircraft’s sleek airframe and highly swept wing designs. An aftermarket elliptical winglet was developed for the Citation X in 2008 to improve range, fuel burn, cruise speed and climb rate. The elliptical winglets were made standard on the modified Citation X+ model which first flew in 2012.

The Citation X is powered by two Rolls-Royce AE3007C turbofan engines, part of a family of engines which power larger aircraft such as the Embraer Legacy 600 and Embraer Regional Jet airliners. The Cessna Citation X’s power to weight ratio allows it to reach a transonic maximum speed of Mach 0.935 (1,155kmh/717mph), and has also meant that the aircraft has broken many speed records, as well as being faster than the Gulfstream G650 ultra-long-range jet.

The Cessna model 680 ‘Citation Sovereign’ is a super-midsize jet developed and manufactured by Cessna in the USA. The Citation Sovereign first flew in 2002 and entered production two years later in 2004.

Based on earlier Citation fuselage designs, the Citation Sovereign features a new swept-wing design with trailing edge flaps for optimised runway performance. The Citation Sovereign typically seats eight passengers in a double club configuration, although it can seat a maximum of 11 passengers in a high-density configuration.

In 2012, Cessna announced the launch of the Citation Sovereign+. The improved model incorporated blended winglets and uprated Pratt and Whitney PW306D turbofan engines for enhanced range performance.

The Cessna 680A Citation Latitude is a super midsize jet designed and manufactured by Cessna in the USA. Introduced in 2011, the Citation Latitude fills a market gap between the smaller Citation Excel and larger Citation Sovereign. The Citation Latitude first flew in 2014 with deliveries commencing the following year. By 2019, just short of 200 Latitudes had been manufactured and delivered globally.

Featuring the same wing design as the Citation Sovereign+, the Latitude is powered by Pratt and Whitney PW306D turbofan engines and has as typical capacity of eight or nine passengers. The flat floor of the Latitude allows for greater comfort, space and ease of movement throughout the cabin.

The Citation Latitude’s transcontinental range makes flights of between four and five hours manageable. Coupled with the aircraft’s extremely spacious and luxurious cabin, the Latitude is the perfect aircraft for short to medium-haul flights.

The Bombardier Challenger 300 series is a family of super-midsize jets developed and built by Bombardier in Canada. Introduced in 1999, the family includes the original Challenger 300, the 350 and, more recently, the Challenger 3500.

Unlike other variants, the Challenger 300 family did not derive from the Challenger 600 series aircraft. Instead, the Challenger 300 was an entirely new design. Since their introduction in 1999, more than 650 Challenger 300 series aircraft have been manufactured, a testament to their proven track record.

The Challenger 350, which first flew twelve years after its predecessor, features many of the original design aspects of the Challenger 300. However, modified features include larger cabin windows, interior design improvements, and minor external alterations such as canted winglets.
