What should pilots do if they notice a discrepancy in avionics during a pre-flight check?

If pilots notice a discrepancy in avionics during a pre-flight check, they should report the issue before proceeding with the flight. This is crucial for safety and compliance with regulatory requirements. Avionics systems are integral to flight safety, providing critical information and functionality like navigation, communication, and monitoring systems. By reporting discrepancies, pilots ensure that necessary inspections and repairs can be conducted, preventing potential safety hazards during flight.

Addressing these issues prior to flight helps maintain the aircraft's operational integrity and assures all flight personnel that the aircraft is fit for safe operation. This protocol also reinforces the importance of pre-flight checks as a part of the overall safety management system within aviation.
