Nextant completely redesigned the engine cowlings and pylons after performing computational fluid dynamics (CFD) analysis. The CFD revealed a supersonic shock wave generating excessive drag between the original engine nacelles and fuselage at normal cruise speeds. The redesign eliminated drag, reduced fuel consumption, delivered additional range and provided for simplified engine service access reducing maintenance downtime and costs.
The 400XTi’s exceptional range for a light-cabin jet is largely due to the revolutionary FJ44- 3AP engine, which is significantly lighter and more fuel efficient than its predecessors (by up to 32 percent). Full Authority Digital Engine Control (FADEC) eliminates the need for a thrust reverser- further reducing weight and operating costs while improving operational reliability. The addition of the auto-throttle saves fuel and greatly reduces pilot workload, especially at critical phases of flight. The engine is also significantly quieter, allowing the 400XTi to meet Category IV noise compliance regulations.
The Rockwell Collins Pro Line 21 avionics system is at the heart of the most modern business aviation cockpits. The uncluttered instrument panel features just 4 LCD screens, and the iconic glass cockpit allows pilots to have a better awareness of flight progress, weather, traffic, and other hazards.
