What must a pilot do when preparing for an ILS approach regarding the aircraft's systems and settings?

When preparing for an ILS (Instrument Landing System) approach, it is essential for a pilot to verify that all systems are set correctly for the approach. This includes ensuring that the navigation systems are correctly tuned to the ILS frequency, verifying that the course and vertical guidance indicators are set for the specific runway, and confirming that autopilot settings, if used, are appropriately configured for capturing and following both the glide slope and localizer signals.

The accuracy of these settings is critical to ensure safe and successful execution of the procedure, particularly in low-visibility conditions where precision guidance is paramount. A thorough pre-approach check helps minimize the risk of errors that could lead to complications during the landing process. Properly configured systems will facilitate smooth descents and alignments with the runway, enhancing overall flight safety and performance during landing.
