What is required to access the fixed FE-36 fire extinguisher in the Forward lavatory on the ERJ 175?

To access the fixed FE-36 fire extinguisher in the Forward lavatory on the ERJ 175, the use of the Maintenance Data Terminal (MDT) is required. This control system allows for the monitoring and controlling of various aircraft systems, including fire suppression systems.

In the context of the ERJ 175, the MDT facilitates the activation of the fire extinguisher, ensuring that appropriate safety procedures are followed. Using the MDT is crucial because it also indicates the readiness and functionality of the fire extinguisher system, thereby enhancing operational safety.

Other options like manual override, remote activation, or visual confirmation are not the standard procedures for accessing this specific fire extinguisher, as the process relies on the capabilities and protocols established within the aircraft's systems, specifically the MDT for such operations.
