Cessna 400

The Cessna 400 ( Cessna 350 ) is a single-engine low-wing monoplane with a fixed undercarriage. The Cessna 350 was a variant with weaker naturally aspirated engine. Originally sold under the designation Cessna 400, the aircraft received as of January 2009 the name Corvalis TT ( for twin turbocharged ). Today's marketing name include: Cessna Corvalis and Corvalis TT Cessna. Prior to the acquisition by Cessna, the aircraft was designated as LC -41 Columbia 400. It was designed by the company as a further development of the Columbia Columbia 300 with a turbocharger and an enlarged tail. It had its first flight in June 2000.

The Cessna 400 is characterized particularly from its aerodynamically sophisticated composite cell, the glass cockpit with components from Garmin or Avidyne and its large interior. The Cessna 400 is comparable performance with aircraft such as Cirrus SR22 GTS or the Mooney Acclaim.

On 27 November 2007, the Cessna Aircraft Company announced the acquisition of individual parts of Columbia. The Columbia 350 and 400 were marketed from that date as Cessna 350/400 for prices of about 530.000/620.000 U.S. dollars.

Today it is delivered under the name Corvalis TTX in the Garmin with two 14 -inch displays and the backup instruments are performed digitally in addition to the G2000 glass cockpit. It is the first piston engine aircraft with no analog instruments.
