Aircraft Systems: Complete Guide for Pilots

All aircraft have the requirement for essential interconnected and integrated systems, the performance of which is critical to safe operations. Most aircraft have a standardized set of systems, and these systems are dependent on some power source. There are also a variety of support systems provided for comfort, regulatory, or human physiological reasons.

This section covers the primary systems found on most aircraft. These include the engine, propeller, induction, ignition, as well as the fuel, lubrication, cooling, electrical, landing gear, and environmental control systems.

Understanding how these systems operate and interact is essential for pilots. Knowledge of their basic functions also helps pilots recognize abnormal indications, understand system limitations, and respond appropriately when a system does not operate as expected.

The following topics introduce the major aircraft systems and provide a foundation for understanding their operation and role in safe aircraft operations.
