Definition
A specific geographic location defined by latitude and longitude (and sometimes altitude) that serves as a reference point for an instrument approach procedure, but is not aligned with a runway. A point-in-space (PinS) approach guides the aircraft to this location, from which the pilot then proceeds visually to a landing area or continues to a missed approach.
Plain English
A fixed spot in the sky used as the target of an instrument approach when there is no runway to line up with. The approach takes you to that spot, and from there you either see your landing area and go in visually, or you fly the missed approach.
Context Anchor
Seen on helicopter instrument approach and departure procedures, and in discussions of continuing from an instrument procedure toward a heliport or other landing area.
Derivation
The phrase is plain English used in a technical sense. 'Point-in-space' literally means a precise location in three-dimensional airspace — defined by coordinates rather than by a physical feature like a runway. The label highlights that the approach's endpoint is a coordinate, not a piece of pavement.
Why Pilots Care
It lets helicopters fly instrument approaches to places without a full runway-aligned approach, expanding safe access in low visibility.
Grounding Statement
Picture a helicopter reaching a marked spot above the ground, then continuing by sight to a nearby helipad only if the pilot can clearly see enough to do so safely.
Intuition Check
A point-in-space is not any random point the pilot chooses in the sky. It is a specific published point built into the procedure.
Example Sentence 1
The helicopter flew the RNAV approach to the point-in-space, then continued visually to the hospital helipad.
Example Sentence 2
At the point-in-space, the pilot transitioned to visual references for the final landing.
