What is the purpose of performing pre-flight checks?

Performing pre-flight checks is crucial for confirming that all systems are functioning properly. This process involves thorough inspection and verification of various aircraft systems to ensure their operational readiness. It encompasses checks of critical systems such as avionics, flight controls, engines, and safety equipment. By ensuring that everything is in working order before takeoff, the pilots are able to identify and address any potential issues that could affect the safety and performance of the flight. This contributes to overall safety for the passengers and crew, aligning with the professional responsibility of the pilots to conduct a safe operation. While aspects like passenger comfort, weather conditions, and cabin crew readiness are important, the primary and most critical focus during pre-flight checks is the operational integrity of the aircraft itself.
