Cessna 320D,E,F

Number of Active Aircraft: 111 Active- Map


The original SkyKnight's were turbocharged variants of the popular natural aspirated 310. The 320 differed from the 310 by an additional window in the back and other options more suited to the business traveller.

The 320 was non pressurized but was one of the fastest twin engine piston aircraft built by Cessna if taken to higher altitudes.
