on parle effectivement de train renforcé .Changes from the basic Su-27
Changes from the shore-based Su-27 were the addition of canards, re-profiled leading-edge root extensions, redesigned folding outer wing panels, seperately controlled aileron and flaps. These changes were supported by an upgraded fly-by-wire control system and hydraulic system.
The Su-27K airframe and landing gear was strengthened to cope with the additional stress from carrier landings. The nose gear was changed to a twin-wheeled one with a telescopic strut and features an additional landing light and three-colour indicator lights for the carrier's flight controller's reference regarding glide-patch and landing speed.
