The aeronautical hydraulic test bench enables trainees to learn in the best possible conditions about the technical specifics, aeronautical maintenance and safety constraints of the aeronautical hydraulics sector.


Learning to maintain aeronautical hydraulics

This teaching equipment has been specially designed for training in aeronautical hydraulic maintenance.

The aim is to provide the best possible learning and safety conditions for vocational baccalaureate, BTS and engineering students, as well as adult learners, by combining this teaching equipment with industrial hydraulic components adapted to the needs of the aeronautical industry.

These teaching aids prevent learners from being exposed to the highly toxic, high-pressure hydraulic fluids found on aircraft, while ensuring their safety and that of their instructors.

Students practice on a specially-designed aeronautical trainer using industrial hydraulic technology components from leading brands, which have the advantage of being much less expensive than aeronautical equipment. They learn how to maintain aircraft/helicopter hydraulic systems in a much more fun and, above all, safer way.

Aérocampus de Bordeaux, an expert in aeronautical maintenance, helped us design this electro-hydraulic control panel and its operating parts, which enable us to put learners through their paces with didactic material based on the specifics of the aeronautical field.

We drew on the skills and experience of Yoann Gac, a qualified teacher and former flight engineer in the French Air Force, to develop and perfect this comprehensive teaching aid.

Purpose of this educational equipment

The training objective is to identify the various components of an aircraft’s hydraulic kinematic chain (landing gear, flap control, etc.), and to connect them hydraulically and electrically using the various component modules and 2 control strips, while complying with the safety conditions essential to this profession.

That’s why we’ve chosen to encapsulate the operating parts, double the hydraulic and electrical safety devices, and protect the hoses with jet-breaking socks and anti-whipping cables.

We have also created a “black box” accessible only to teachers/trainers, which can be used to trigger electrical faults on the circuits.

A case of components found to be defective is supplied for hydraulic troubleshooting at various points in the circuit.

Our bench enables us to carry out practical work in the best possible conditions, so that students can grasp the specifics.

ECAM automatic display and control unit


This new-generation industrial HMI controller represents an Ecam screen that you’d normally find in aircraft cockpits.

The sensors connected to the PLC and the LEDs on the landing gear & flap control panel enable you to monitor the correct functioning of the movement sequences during the operating cycles of the operating parts, gear and flap (Wheel and Flapi).

A “Hydraulic Diagram” tab will be available for students to understand the various hydraulic and electrical circuits of the equipment.

You’ll also be able to access tutorials and a number of videos, as this PLC is able to read PDF and mp3 formats.

A “Graph” tab is available for interpretation and analysis of curves related to flow, pressure or temperature.

Aeronautical landing gear operating part

Operating part Landing gear POTA-V2

This “Landing gear” section reproduces the same kinematic cycle for opening the landing gear and the aircraft hatch. The hatch is opened by a hydraulic cylinder and then locked in position (indicator light and position sensors).

The landing gear is controlled by a jack, which also deploys to complete its movement, and to complete the cycle, the hatch closes on itself.

The various stages of the cycle are validated by sensors which authorize or disable the next movement.

Aeronautical section

Operating part POV-V2 shutter

We have reproduced the kinematics of a shutter with the possibility of hydraulic “on/off” control, but also proportional control.

The digital board and its software integrated into the PCA-V2 control panel enable you to control shutter movement in open loop or position control with its linear potentiometer (4 positions in closed loop with 4 position sensors).

A compass is fitted to this flap and communicates its angular displacement.

GS service unit

GS service unit

The purpose of this unit is to provide adjustable pressure and flow, thus replacing the aircraft’s functions (the PCA-V2 console will become the aircraft in this case).
and therefore replace the aircraft’s pump unit.

Module holders
The module holder is the ideal accessory for front-mounted training benches.

All modules are stored in one place and are easy to attach. It allows you to hang all the hydraulic hoses you need for your practical work.
