What happens to the inboard brakes if hydraulic system 3 is lost?

They remain operational
They will lose partial functionality
They will be completely lost
They will operate automatically

The correct answer is: They will be completely lost

The inboard brakes on the Canadair Regional Jet rely on the hydraulic system for their operation. If hydraulic system 3 is lost, the functionality of the inboard brakes is entirely dependent on that system. As such, losing hydraulic system 3 leads to a complete loss of braking capability for the inboard brakes. This means that without hydraulic pressure supplied from system 3, the inboard brakes cannot engage or function at all. In contrast, the other options imply some level of operational capability, whether partial or complete, which is not the case here. The brakes do not retain any operational status without the necessary hydraulic support, making it clear why the complete loss of functionality is the accurate response in this scenario.
