For the last couple nights we have been installing piers at the Thunder Bay International Airport in order to support a new PAPI light system. PAPI lights,( Precision Approach Path Indicator )are visual navigation aids which provide guidance information to help pilots acquire and maintain the correct approach angle to an airport. Being that these lights have nearly zero tolerance to movement and vibration, custom 14' long piers were installed to ensure that they will maintain proper adjustment for as long as they remain in service.
