Bleed-type air nozzles are typically found on which systems?

Bleed-type air nozzles are a fundamental component in both RSA and TCM fuel metering systems. These nozzles function by utilizing air, often referred to as "bleed air," to control fuel flow and ensure accurate fuel metering during various phases of engine operation.

In the context of the RSA system, bleed-type air nozzles help optimize air flow into the metering system, enhancing the performance and response of the fuel delivery process. Similarly, in a TCM system, these nozzles play a crucial role in maintaining the appropriate pressure and flow characteristics necessary for the efficient operation of the fuel system.

The presence of bleed-type air nozzles in both systems illustrates their importance in aircraft fuel management, particularly in controlling fuel-air mixtures to achieve efficient combustion. This integration into both types of metering systems makes the correct answer comprehensive, reinforcing their essential role in modern aviation fuel systems.
