ACU

Aircraft communications system

In the context of aviation and aerospace, an Aircraft Communications System (ACS) refers to the integrated system of equipment, protocols, and procedures that enable communication between an aircraft and various stakeholders, including:

Antenna control unit

In the context of aviation and aerospace, an Antenna Control Unit (ACU) is an electronic device that controls and manages the operation of antennas used in aircraft and spacecraft communication systems. The ACU is responsible for selecting the correct antenna, configuring the antenna's operating parameters, and ensuring that the antenna is functioning properly.

Apron control unit

In the context of aviation and aerospace, an "Apron Control Unit" (ACU) refers to a system or device used to manage and control aircraft movements on the apron, which is the area of an airport where aircraft are parked, fueled, and serviced.

Autopilot control unit

In the context of aviation and aerospace, an "Autopilot control unit" (ACU) is a component of an autopilot system that controls and stabilizes an aircraft's flight trajectory. The autopilot control unit is essentially the "brain" of the autopilot system, responsible for receiving and processing data from various sensors and systems to make adjustments to the aircraft's flight control surfaces.
