Identify two types of aircraft systems that crew members must be familiar with.

Crew members must be familiar with avionics systems and propulsion systems because these are critical to the safe operation of the aircraft.

Avionics systems encompass a wide range of electronic systems used in aircraft, including navigation, communication, and flight control systems. Understanding avionics is essential for crew members, as these systems play a vital role in managing flight operations and ensuring the aircraft is being navigated accurately and safely.

Propulsion systems, which include the engines and associated systems, are fundamental to an aircraft’s ability to take off, maintain flight, and land. Knowledge of propulsion systems allows crew members to understand engine performance, troubleshoot potential issues, and respond effectively in various flight scenarios.

While other systems, such as cabin comfort and communication systems, are important for passenger experience and crew coordination, they do not have as direct an impact on the critical operational capabilities of the aircraft compared to avionics and propulsion systems. Thus, familiarity with avionics and propulsion is essential for ensuring overall flight safety and effectiveness.
