What is field cleaning?

• A. The procedure for removing accumulation of dirt deposits on compressor blades
• B. The process of cooling the engine
• C. The method of cleaning fuel injectors
• D. The process of cleaning combustion chambers

Answer: (A)

Field cleaning is cleaning done on-site to remove dirt and deposits that build up on the compressor blades. Those deposits disrupt the airflow, reduce efficiency and pressure recovery, and can raise fuel consumption or risk surge. The best answer describes the procedure for removing this accumulated dirt from the compressor blades, which is exactly what field cleaning targets. Other tasks listed are different maintenance activities (cooling the engine, cleaning fuel injectors, or cleaning combustion chambers) and do not describe the on-site removal of deposits from the compressor blades.
