FS98 EYA Air File For AS-365. EYA (Enjoy Your Aircraft) .air file for Aerospatiale AS-365N-2, FS98 design by Ian Standfast, repaint as Proteccion Civil by Gaylen Cates (PROCIVIL.ZIP). With this .air file rework, a better control with a force feedback joystick was intended. Without neglecting the typical secondary reactions of a helicopter control is more moderate. Special hints to what's new in the Dauphin's flight dynamics are included. By Christoph Ruhtenberg.
