Nick Subbotin of the Airport Technology Research & Development (ATR) branch and support technicians Scott Smith and Matt McGown installed custom baffles on a Precision Approach Path Indicator (PAPI) lighting system, a visual reference used by pilots to maintain the correct glide slope during their final approach to landing, at Hollywood Burbank Airport (BUR) in Burbank, CA. Baffles were requested at BUR to satisfy Flight Inspection criteria due to mountainous terrain in the approach path. Custom metal shields called baffles, were installed inside of the PAPI that block the light signal in the vicinity of the mountainous terrain. Pilots will have to fly closer to the runway centerline to see the PAPI light signal and away from the terrain.  Flight Inspection Services will determine if the result is satisfactory and commissioned for use in the National Airspace System.
