The CESSNA CITATION ASTRA has aerodynamic wings and the new airframe design was credited with increasing the IFR range and allowing zero flap takeoffs.
PRIVATE JET CHARTER in a CITATION ASTRA SP and you get performance. The "Astra SP" made leaps and bounds from the original. Its range increased from 2,755 nautical miles to 2,815 nm due largely to aerodynamic features. Additionally, the SP benefited from a 400 pound increase in its hot/high climb limit.
