Final answer:
The LGCIU functions to control and monitor the landing gear system of an aircraft, ensuring safe operation during takeoff, landing, and taxiing. It receives signals from sensors, controls the extension and retraction of the landing gear, and interfaces with the cockpit controls. The LGCIU also provides warnings and indications in case of faults or abnormalities in the landing gear system.
Step-by-step explanation:
The function of the 2 Landing Gear Control and Interface Units (LGCIU) is to control and monitor the landing gear system of an aircraft. They play a crucial role in the safe operation of an aircraft's landing gear during takeoff, landing, and taxiing.
The LGCIUs receive signals from various sensors, such as the weight-on-wheels sensors and landing gear position sensors, and use that information to control the extension and retraction of the landing gear. They also interface with the cockpit controls, allowing the pilot to operate the landing gear.
In case of any faults or abnormalities detected in the landing gear system, the LGCIUs provide warnings and indications to the cockpit, enabling the crew to take appropriate actions for safe landing or troubleshooting.
