What should a pilot focus on when performing an IFR approach?

When performing an IFR approach, the focus should be on using onboard instruments for navigation. This is because IFR (Instrument Flight Rules) operations are designed for flying in conditions where visual references outside the cockpit are limited or nonexistent. Relying on onboard instruments ensures that the pilot can maintain control of the aircraft and navigate precisely, using data such as altitude, heading, and position relative to the approach path.

Using onboard instruments also enhances safety by allowing pilots to make data-driven decisions based on what the instruments indicate, rather than depending on visual cues that may not be reliable. Instruments like the altimeter, attitude indicator, and navigation displays are essential for safe IFR operations, especially during approaches when precise navigation is crucial to avoid terrain and other obstacles.

Navigating based on visual aids or following manual charts without instruments disregard the fundamental requirement of IFR operations, which necessitates responsible reliance on instruments. Similarly, input from passengers may not provide reliable information needed for navigation or situational awareness.
