What is an Instrument Approach Procedure?

• A. Lateral navigation guidance for en-route flight
• B. Set of predetermined maneuvers for landing
• C. Weather briefing for approach
• D. Checklist for takeoff

Answer: (B)

An Instrument Approach Procedure is a published, predefined sequence of maneuvers that guides a flight from the initial approach through to a safe landing when operating under instrument conditions. It specifies a controlled path to align with the runway, including course instructions, altitude constraints, descent paths, and minimums at which a landing decision must be made or a missed approach initiated. This enables crews to descend and maneuver safely in reduced visibility or poor weather. Examples include ILS, VOR, RNAV (GPS) and localizer approaches, each with a final approach path to the runway. The set of predetermined maneuvers for landing best captures this concept, whereas the other items describe en-route navigation, weather briefings, or takeoff checklists, which are not what an instrument approach defines.
