What is the term for a maneuver conducted when an instrument approach cannot be safely completed?

The term for a maneuver conducted when an instrument approach cannot be safely completed is the missed approach. This procedure is specifically designed to ensure safety when an aircraft cannot land due to various reasons such as poor visibility, obstruction on the runway, or any other issue that makes landing unsafe. During a missed approach, the pilot follows a predetermined set of instructions to climb away from the approach path and either circle to try another approach or divert to a different airport.

The missed approach procedure includes specific altitude and navigation instructions that are crucial for safe operation, allowing pilots to transition smoothly to a safe altitude and confirm alternate options without immediate panic or disarray.

Other terms, while relevant to aviation, do not describe the same situation. A go-around typically refers to a scenario where the pilot decides to abort the landing attempt while still within the approach phase but might still be able to attempt landing again. A return to base involves going back to the airport of departure, which isn’t specific to the missed approach context. Final approach refers to the last segment of the landing sequence, just before touchdown, which is not applicable if the landing cannot be safely completed.
