Yellowstone Airport Receives Upgrade

July 1, 2022

WYS upgrade

Yellowstone Airport recently installed a new Precision Approach Path Indicator (PAPI). This new LED approach light uses less energy and replaced the old and problematic PAPI which required a tremendous amount of maintenance over the last several years. The PAPI provides vertical guidance to approaching aircraft for Runway 1. The lights are adjusted to ensure a smooth decent at 3 degrees to the runway while transitioning from the traffic pattern for landing. This project was funded entirely by the Federal Aviation Administration with 100% federal Airport Improvement Program Funding.
