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

The position of PAPI stakes is tied to giving pilots a reliable, consistent glide-path cue from the approach. The inboard PAPI stake marks the inner edge of the light array and is standardized to sit 50 feet from the left edge of the runway. This offset keeps the lights in the pilot’s proper view along the approach corridor and ensures the glide-path indication remains accurate and easy to interpret as you approach. Distances such as 25 or 35 feet would place the stake too close to the edge, and 80 feet would be too far for the inboard position, which is why 50 feet is the correct placement.
