The outboard PAPI stake is placed how many feet from the left edge of the runway?

The PAPI is positioned so its lights create the correct visual glide path for pilots on final approach, which requires a precise lateral offset from the runway edge. The outboard PAPI stake is placed 80 feet from the left edge to achieve that standard lateral position, keeping the lighting clear of the edge, shoulders, and markings while ensuring the glide slope appears correctly to approaching aircraft. Distances like 25, 35, or 50 feet would place the stake too close to the edge or misaligned with the intended path, so 80 feet is the designated offset in this context.
