Power

The emergency locator transmitter (ELT) control panel gets 28v dc or 16v dc from the master dim and test (MD&T) circuit. This power is for the ELT light.

The ELT uses an internal battery pack. The battery pack has four D size lithium manganese dioxide cells. The cells connect in series to supply 6v dc to the ELT.
