[6] The Silvercrest was planned for the larger Citation Hemisphere, but Textron suspended its development in July 2019 as the turbofan did not meet objectives.

The six-passenger Latitude fuselage has been reinforced and stretched by another row of seats to accommodate eight people in double club.

At its Mach 0.83, 473 kn (876 km/h) TAS max cruise, fuel flow per side is 860–880 lb (390–400 kg) per hour at FL430 and ISA -4.

[1] The second flew in November, and in March 2017 the third, used to develop avionics and systems and to collect flight simulator data before two others will join the test program.

[12] 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.

[15] In February 2018, as the five aircraft accumulated over 1,000 flights and 2,000 hours, US approval and customer deliveries of the US$27 million jet were expected before the end of the second quarter before European validation six months later.

[18] 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 had to be submitted by October 1, 2018.

[20] After 4,050 hours in 1,650 test flights, the Longitude received a provisional FAA type certification on December 20, allowing deliveries in early 2019.

[21] The fuel tank flammability requirements were addressed on December 5, with airplanes to be delivered having the definitive installation but limiting it for high elevation airport or RVSM operations, and restricting maintenance.
