“Pilots spend a significant portion of their time monitoring flight systems to ensure efficiency and safety. However, automated systems can fail. If a failure occurs, a pilot must be prepared to resume control, potentially in a high-stress environment. Automation relies on the integration of multiple components, and a failure in one area can require the pilot to fly manually. Every pilot should strive to maintain strong manual skills for these situations.”
