The ~$5 million HondaJet has claims to what could be advances in aircraft design, including a unique over-the-wing engine-mount that is said to improve aircraft performance and fuel efficiency by reducing aerodynamic drag. However, this claim awaits FAA-certified production aircraft powered by two new design GE Honda HF120 turbofan jet engines. The small business jet market has long been dominated by Wichita-based Cessna, of course, which pioneered the idea of turbofan engines and manufacturer-supplied maintenance – and guaranteed costs for owners – in business aviation with its successful Citation line starting in the 1970s.
