The usual term is aircraft position or, more specifically, its spot or parking position in the hangar. If you mean the exact placement relative to the building, people might also say location , bay position , or hangar parking position.

Most natural wording

  • Parking position : best if you mean where the plane is parked.
  • Spot : common in casual or operational language.
  • Bay position : useful if the hangar is divided into marked sections.
  • Aircraft location : broad and clear, especially in records or tracking.

Plain-English answer

If you’re naming it in one short phrase, “hangar position” or “parking position in the hangar” sounds most natural. For aviation paperwork or software, “aircraft location” is often the cleanest term.

TL;DR: “hangar position” is a good general phrase, and “parking position” is the most natural if you mean where the plane sits inside the hangar.
