(ECPU) is part of a family of Cockpit Display Unit
(CDU) products that are available for use on both
military and commercial aircraft.

reporting (displaying) or relaying information (com-
municating) via the communications I/Os on the CDU.

with wide viewing angle technology and operates in
temperatures of -30°C to +85°C.
