The CJ1+ is a turbofan-powered light corporate jet built by Cessna and developed as an improved version of the Citation CJ1. It has two Williams International FJ-44-1AP engines, which are specialized for this model aircraft specifically because they allow it to have more efficient fuel consumption than its predecessors in addition to other benefits like better performance overall.

The plane was first revealed at NBAA’s annual convention in 2004 after undergoing testing with FAA certification granted less than a year later thanks to improvements made such that not only does it run cleaner but also faster while maintaining good range capabilities so long as you’re willing maintain speeds below Mach .82 vs just being limited by maximum altitude before having increased power output available up high
