What you need to know
Precision approaches (like ILS) give you both lateral and vertical guidance down to a Decision Altitude/Decision Height, and the core skill being tested is disciplined execution: correctly tuning and identifying the navaid before relying on it, staying stabilized on speed, configuration, and descent rate throughout, and making a firm go/no-go decision at DA/DH based solely on what you can see. You must never continue descent below DA/DH without the required visual references in sight, and any deviation—whether from ATC instruction, deteriorating weather, an unstable approach, or a suspected instrument malfunction—demands prompt recognition and correction rather than pressing on. Good judgment also means catching unreasonable descent rates or automation misbehavior (autopilot/flight director not doing what you commanded) early, cross-checking raw data against automated displays, and being ready to hand-fly or go missed if things don't add up. Throughout, timely ATC communication and correct readbacks are expected as part of safely managing the approach, not just as a formality.
Why students miss this
Students often treat Decision Altitude/Height as a hard floor they can 'level off and look' at, when the real rule is a continuous decision: if the required visual reference isn't there exactly at DA/DH, the missed approach must already be underway, not started after a pause to check. A related trap is confusing DA/DH stabilization criteria with non-precision MDA logic, leading pilots to think brief descent below DA while searching for the runway is acceptable the way it sometimes gets rationalized at MDA.
Focus on: Drill the concept that at a precision approach's DA/DH, the missed approach is initiated at the moment of reaching that altitude unless the visual references are already clearly in sight, with no dip-and-look allowed.

AA.VI.E.R3 came from a question you missed on the FAA Airline Transport Pilot Multiengine Airplane knowledge test. Take a free, ACS-aligned Equipment, Navigation, and Facilities quiz — instant scoring, explanations, and the cited FAA reference behind every answer.
Missing it isn't a verdict on you — it's a sign your prep skipped the why behind it. Memorizing answer letters is exactly what leaves gaps like this. Here, every answer explains the reasoning and cites the FAA source it comes from, so the concept holds on test day and at the checkride oral.

Common question
Is there any situation where a pilot can legally go below DA/DH without the runway environment in sight?
No — at DA/DH the pilot must have the required visual references to continue; if not, the missed approach must begin right at that altitude, not after descending further to check.
What is an FAA ACS code?
The FAA's Airman Certification Standards (ACS) break each certificate into Areas of Operation, Tasks, and specific Knowledge (K), Risk Management (R), and Skill (S) elements. Every knowledge-test question maps to one code like AA.VI.E.R3. When you miss a question, your Airman Knowledge Test Report lists its code so you know exactly what to review.
