The DX1 is an engine and systems display that indirectly obtains real-time information from remote units like the TSLM, TM1, PDC, and FSM. It has a local fuel interface to derive information such as fuel flow, fuel pressure, fuel quantities, fuel remaining, and more. The table below gives the functionality:
