Hydraulic System Main Unit (Module)


Aircraft Hydraulic System Trainer provides students with practical experience needed to understand the function, to get to know components and to improve troubleshooting skills. Fully functional hydraulic system designed so that every component can be disassembled, reassembled and functionally tested. All the components mounted on the trainer are operational, removable and they can be reinstalled.

NOTE: EICAS/ECAM screen is located on the hydraulic landing gear trainer or main unit.

NOTE: Hydraulic System Main Unit UHT-100V is basically a hydraulic power unit which provides hydraulic pressure to operate the HYD-100V Landing Gear Module. UHT-100V can not be operated without HYD-100V
