  • Eliminates yaw damper inoperative altitude limits, increasing your dispatch reliability
  • Improved directional stability and pilot control
  • Reduced drag in all flight modes
  • Improved passenger ride quality
  • Quieter cabin and cockpit
  • Increased climb and cruise performance
  • Inherently reduced minimum control airspeed


Wing/body vortices normally disrupt airflow under the aft fuselage, creating drag. Dual Aft Body Strakes eliminate this separation, channeling the vortices and accelerating the air -- in effect, pushing the airplane through the air.

Technology Benefits:
  • Classic Beech ventral fin is removed
  • The shedding wing/body vortices are captured under the aft fuselage pressurizing and reducing aft-body drag resulting coanda-effect attaches the aft-body airflow
  • Equivalent vertical tail area is increased
