Definition
Published instrument approach procedures designed for, or usable by, helicopters operating under instrument flight rules (IFR), allowing a helicopter to descend through clouds or low visibility to a point from which a landing can be made visually. These approaches may be standard procedures shared with airplanes, copter-only versions of those procedures (often identified with 'COPTER' in the title), or point-in-space approaches that terminate at a fix from which the pilot proceeds visually to a landing area such as a hospital helipad or oil platform.
Plain English
Step-by-step routes a helicopter pilot can fly using only cockpit instruments to safely come down through bad weather and reach a point where they can see well enough to land.
Context Anchor
Seen on instrument approach charts, in helicopter instrument training, and when planning or flying an arrival in weather that limits outside view.
Derivation
Helicopter comes from Greek roots meaning “spiral” or “turning” and “wing,” referring to the turning blades that lift the aircraft. Approach comes from words meaning “to come nearer.” Together, the phrase means a helicopter coming nearer to landing by following a formal instrument-guided path.
Why Pilots Care
Allows helicopters to reach destinations and complete missions when visual approaches are impossible due to weather or darkness.
Grounding Statement
Picture a helicopter above a low cloud layer, following a charted path on instruments until the pilot can safely see the landing area below.
Intuition Check
Do not read “instrument” as just the gauges in the panel, and do not read “approach” as simply getting closer to the airport. Here, the phrase means a published procedure for descending safely when outside visual reference is limited.
Example Sentence 1
Because the ceiling was 400 feet, the pilot chose a helicopter instrument approach into the hospital helipad rather than diverting.
Example Sentence 2
After the missed approach, the crew requested vectors for another helicopter instrument approach to the alternate airport.
