On the LR configuration, where are the PBE units located?

• A. LR: Aisle-side compartment and last overhead bin.
• B. LR: FWD equipment closet and last overhead bin.
• C. LR: Aisle-side compartment and first overhead bin.
• D. LR: Aft equipment closet and mid overhead bin.

Answer: (A)

PBE units are placed to ensure quick access from the aisle and from the rear of the cabin during an emergency. In the LR configuration, one PBE is kept in an aisle-side compartment so crew can grab it fast as they move through the aisle and address a smoke or fire scenario. The second PBE is located in the last overhead bin, which keeps a unit accessible toward the rear of the cabin and avoids being tucked away in a closet or in a position that would be harder to reach during an urgent situation. Placing a unit in a forward equipment closet or in a mid or first overhead bin would reduce accessibility when smoke or fire blocks parts of the cabin or when time is critical. This arrangement—aisle-side compartment and last overhead bin—supports rapid, two-direction access for the crew in LR configuration.
