You don’t have to take our word for it: It has been proven many times over by military and commercial aircraft operators—as well any industry depending on large, powerful diesel and turbine engines—that active monitoring and data analysis can prevent failure and reduce the overall cost of operation. These days, sophisticated computerized engine controls are common in many applications, but the typical piston-powered aircraft still runs with instrumentation based on 1930s technology.
Looking back, the results were predictable, but the pilots and operators of earlier aircraft rarely had a choice. Advances in technology today allow precise engine monitoring and data evaluation so as to accurately predict and prevent upcoming partial or complete engine failures. In fact, monitoring has improved to the point that it’s rare for a modern and properly maintained—and operated—piston aircraft engine to fail without some kind of warning. The operator’s job is to conduct appropriate monitoring and analysis, and then to act when the data indicate a problem. Establishing an engine monitoring program and the minimal investment in equipment and training can be a significant factor in improving safety and reducing the overall cost of operation.
