With dimensions reduced to the minimum, the B-Pit puts at disposal directly at the aircraft parking position a 400 Hz power supply or a 50 Hz socket (up to 250 A) for a PCA group or any other equipment requiring a significant electric power.

Once all cables are connected, the Hatch pit can work in closed position.

The manhole (in option), next to the hatch, makes any maintenance fast and without effort.

The B-Pits can be associated in parallel in the same concrete pit, for the supply of different utilities.
