Where is the MDT located on the ERJ 175?

The Maintenance Data Terminal (MDT) on the ERJ 175 is indeed located under the forward (FWD) and aft (AFT) flight attendant jumpseats. This location is chosen for practical reasons: it is a discreet area that minimizes the chance of interference with cabin operations while still providing easy access for crew members and maintenance personnel when needed.

The MDT is used to communicate vital data about the aircraft's systems, which helps in diagnosing issues and performing maintenance. Placing it in this location ensures that it is close enough for flight attendants to access if needed while remaining out of the way of passenger activities.

Locating the MDT in the cockpit, overhead bin, or behind the last row of seats would impede accessibility, create clutter in passenger areas, or complicate communication during maintenance checks. Therefore, the correct position under the jumpseats supports operational efficiency and facilitates maintenance tasks.
