Cessna has completed initial ground engine tests on its new mid-size Citation Longitude, ahead of first flight of the prototype aircraft in the coming weeks.


The test verified functionality of the Honeywell HTF7700L turbofan engine's start, fuel system and auto-throttle as well as interfaces with the avionics, electrical and hydraulic systems.

The aircraft will proceed to a series of functional and structural tests on the airframe in preparation for first flight.

Cessna successfully mated the wing and fuselage of the first Longitude in May, just six months after unveiling details of the super-midsize jet, and powered the electrical distribution system for the first time in June.

The aircraft is designed specifically for maximum passenger comfort and offers the lowest cabin altitude in its class at 5,950 feet, with seating for up to 12 passengers, the Longitude features a stand-up, flat-floor cabin with a standard double-club configuration and a class leading walk-in baggage compartment fully accessible in flight.

The clean sheet design features the next evolution of the Garmin G5000 flight deck and is powered by FADEC-equipped Honeywell HTF7700L turbofan engines with fully integrated autothrottles.

The aircraft offers a full fuel payload of 1,500 pounds, a maximum cruise speed of 476 knots and a high-speed range of 3,400 nautical miles. With optional head-up display and enhanced vision capability, the Longitude facilitates eyes-up flying.
