This scenario-based instrument approach discussion is designed to sharpen real-world IFR decision-making skills. The first scenario is flown at night in IMC by a fatigued pilot, emphasizing missed approach planning before FAF intercept, DME arc tracking, and the compounding risks of fatigue and deteriorating weather. The second scenario covers an approach in deteriorating conditions, exploring glide slope failure procedures, in-flight runway changes, and when to execute a missed approach even on a "salvageable" approach. We will address five critical IFR proficiency areas: briefing the missed approach before starting down, making go​/​no-go decisions before the FAF, managing runway changes while in holding, mitigating fatigue in night IMC, and understanding primary versus alternate missed approach procedures. The material is intended for instrument-rated pilots and flight instructors seeking to strengthen aeronautical decision-making through realistic, chair-flying exercises. — Skyfarer is not affiliated with the FAA.
