To ensure reliability, what should pilots do regarding backup instruments?

Ensuring the reliability of backup instruments is crucial for pilot safety, particularly in instrument flying conditions. Setting and checking backup instruments before flight allows pilots to verify that those instruments are functioning correctly and that they can be relied upon if needed. This pre-flight preparation is an essential part of standard operating procedures and helps prevent in-flight surprises.

By confirming the functionality and accuracy of backup instruments before embarking on a flight, pilots create a safety net that can be critical during moments of failure in the primary flight instruments. This proactive approach helps ensure that all necessary instruments are ready for use in case they are required, especially during adverse weather conditions or system malfunctions.

This practice also familiarizes pilots with the operation of backup instruments, ensuring that they are comfortable and knowledgeable about using them should the situation arise. By taking these steps, pilots contribute to a higher level of safety and reliability during their flights.
