KSA Design Engineer, Michael Shangreaux, EIT, helped design, install and acquire funding for the first LED PAPI system in Texas at the Taylor Municipal Airport. “PAPI” stands for Precision Approach Path Indicator. PAPI systems are used by pilots as a visual guidance system on the ground that assists in landing their planes safely. As pilots approach the Taylor Municipal Airport, the LED PAPI system will use a combination of red and white lights to indicate if they are on the correct trajectory, or if they are too high or too low.

The LED lights that are used in the PAPI system at the Taylor Municipal Airport are beneficial to the environment using 62% to 80% less energy than incandescent lights used in traditional PAPI systems depending on the operation mode. The LED’s are cost effective and require less maintenance. Using a Style A (Voltage Powered) LED PAPI generally has a reduced installation cost over the conventional PAPI system. The TxDOT Aviation Division funded 90% of the LED PAPI system as part of Taylor’s CIP. This is the first instance of TxDOT funds being used for LED PAPI systems in Texas. Using LED lights in PAPI systems are becoming more popular because of their green sustainability and cost effectiveness.
