New environmental control system (ECS)
The 747-8's environmental control system is derived from the 767-400ER.
The 747-8 uses an advanced ECS similar to the system used on the 767-400 Extended Range. This system features digital control, lighter weight, increased reliability, and reduced maintenance. (Image represents the Boeing 767-400 ECS)
