Citation Longitude completes initial ground tests


Cessna’s new $23.9 million Citation Longitude has completed the initial ground testing of its Honeywell HTF7700L engines.

The testing included verification of the engine fuel system and auto-throttle, as well as interfaces with the avionics, electrical and hydraulic systems.

“The engine run tests are one of the final major milestones as we prepare for first flight,” said Scott Ernest, president and CEO, Textron Aviation. “This step really allows us to prove the maturity of the aircraft and its systems. Following this, we will do a series of functional and structural tests on the airframe in preparation for first flight. The speed at which we are progressing on the Longitude program demonstrates our industry-leading development cycle and affirms our commitment to new product investment.”

The Textron Aviation company is now working towards the first flight of the aircraft, which was originally expected to take place in the coming weeks.

Honeywell’s HTF7000 series engines are also used on the Bombardier Challenger 350, Embraer 450 / 500 and Gulfstream G280.
