What components are located on the AGB?

The correct answer identifies the components located on the accessory gearbox (AGB) as three pumps, two generators, and one air turbine starter.

In the context of aircraft systems, the AGB is crucial because it houses essential components that provide power and manage critical systems. The three pumps typically refer to fuel pumps and hydraulic pumps, which are vital for engine operation and control. The inclusion of two generators is significant because they provide electrical power to the aircraft systems, and having two ensures redundancy, which is key for reliability in flight operations. The one air turbine starter included in this configuration is responsible for initiating the engine start sequence, a critical function for starting the engine and thus the entire aircraft operation.

In aviation, redundancy and reliability are paramount; having multiple generators ensures that if one fails, the other can continue to power essential systems. The configuration of components on the AGB is specifically designed to optimize performance while ensuring safety and operational reliability. This design philosophy is reflected in the selected answer, making it the most accurate description of the AGB's components.
