If by any chance there is an engine failure, the Emergency Power Unit (EPU) starts automatically in order to provide the plane with the required hydraulic pressure of the primary system. The EPU can run for about 10 minutes due to an own fuel reserve which can be monitored with EPU Fuel Indicator. When the EPU is running the hydraulic system B is inoperative. When the EPU has no more fuel, both hydraulic systems fail, making the flying of the aircraft impossible. Under these conditions ejection should be done. This panel is located on the left console.
The model was created in Blender 2.93 for the Cycles engine, the textures and materials are PBR based. The model has been rigged with a simple Empty for easy animation.
NOTE: I tried to keep all the materials packed within the .blend but if for some reason it is not here, you can find them on the Texture folder in the .zip file that accompanies this panel or if you still require it, don't hesitate in contacting me.
