What happens to the compressed air taken from the engines?

Compressed air taken from the engines is primarily utilized for various pneumatic systems. This air is essential for numerous functions, including starting the engines, operating instruments, and powering tools and equipment within the aircraft. The use of compressed air is vital in maintaining the operational efficiency of the aircraft and ensuring that systems reliant on pneumatic power are functioning correctly.

In this context, while venting air into the atmosphere might occur in specific situations, it is not a primary function of the compressed air system. Similarly, although the compressed air could indirectly contribute to some cooling effects, particularly through its use in certain pneumatic systems, its main role is not to cool the engines. Storing compressed air in tanks may be applicable in some systems, but the immediate application of engine-compressed air is typically directed towards operational systems rather than storage.
