The Cessna Citation Longitude (Model 700) is a 3,500 nmi (6,500 km) range
business jet, part of the Cessna Citation family. Announced at the May 2012
EBACE, it made its first flight on October 8, 2016, certification is expected in
the third quarter of 2018 with deliveries later in the same year. Powered by
Honeywell HTF7000 turbofans, The aluminum airframe has the fuselage
swept wing and a T-tail.
The project is perceived as the follow-on development to the now-canceled Cessna
Citation Columbus. Its fuselage cross-section (83.25 inch circular section) is
the same as the Cessna Citation Latitude. The aircraft has a T-tail empennage
and area rule fuselage contouring. The aluminum wings incorporate moderate
winglets. Construction is aluminum for both wing and fuselage. The cabin is 7
inches shorter and 6 inches narrower than the Columbus design.
Initially, the Snecma Silvercrest engine was selected to power the aircraft,
however the production model is powered by Honeywell HTF7000 turbofans. The
Silvercrest will be used for the larger Citation Hemisphere.
Its wings and empennage are similar to the Hawker 4000 with winglets leading to
a 5.3 ft. larger wingspan. The moderately super-critical wing have a
section. The six-passenger Latitude fuselage has been reinforced and stretched
by another row of seats to accommodate eight people in double club. The
manufacturer has not announced the final design weights (as of May 2016); BCA
width is 6 ft. 5 in., floor width is 4 ft. 1 in and cabin length is 25 ft.

Developed into
Cessna Citation Hemisphere
Less than eight months after the first flight and after more than 200 missions
for nearly 400 hours, on track for certification later in 2017, the fourth
prototype joined the flight-test program on May 6, fully outfitted for interior,
environmental control system, pressurization and cabin technologies evaluation.
The first production unit was rolled out on June 13, 2017 as the four test
aircraft have flown 550 hours and a fifth aircraft will join in summer 2017. In
October 2017, test aircraft have completed more than 1,200 flight hours over 600
flights, for a certification expected by the end of 2017 or in early 2018.
In February 2018, as the five aircraft accumulated over 1,000 flights and 2,000
hours, US approval and customer deliveries were expected before the end of the
second quarter before European validation six months later. After 3,000 hours on
five aircraft, flight testing will conclude by early June 2018, and 200,000
pages of documentation will be completed after a month. As testing has doubled
for certification, expanding related documentation, it is expected in the third
quarter of 2018 with deliveries from late in this quarter or early in the
fourth, less than a year after originally planned. It received a partial
exemption for fuel tank flammability requirements applicable through January
2020 to keep its third-quarter approval goal, but a compliance plan have to be
submitted by October 1.
On October 15, 2018, fractional operator NetJets announced the purchase of up to
175 Longitudes, sold for $26 million each, along 150 Citation Hemispheres,
priced at $35 million.
