The CJ1+ is a new and improved version of the Citation Jet 1. It has two Williams International FJ-44-1AP engines, which are capable of producing more thrusts than its predecessor’s engine. The performance level on this jet model also increased by a significant amount because it offers fuel efficiency, making it an ideal option for small businesses looking to invest in their own aircraft or individuals who want reliable and fast travel that doesn’t sacrifice time away from work.
