PAPI Precision Approach Path Indicator - 1

Approach & Navigational Aids Section Head Precision Approach Path Indicator Compliances: FAA: AC 150/5345-28 Current Edition: L-880 and L-881 ICAO Annex 14 Applications The PAPI System provides the pilot a positive visual indication of the aircraft’s position relative to the optimal glide slope during final approach to the runway. The L-880 PAPI system consists of four units in a line or bar, each unit having two or three 200 watt lamps. The PAPI unit produces a beam of light, the upper portion being white, the lower red. As the pilot’s vertical position changes, the color of the light as seen by the pilot changes instantaneously. The Style A PAPI uses a Power and Control Unit (PCU) which has a photocell for automatic day/night intensity control. The PCU can be operated by using an L-854 radio controller signaled by an approaching aircraft. The Style B PAPI is powered by an L-828 constant current regulator. Style B does not include isolation transformers or connector kits, please order those separately. Features PAPI UNIT ETL Certified 1000 Hour Lamps Meets ICAO Recommendations Sharp Signal Transition: less than 3 Minutes of Arc Precise Setting Tool: ±2 Minutes of Arc (not included with PAPI unit) Ordering Information How to Order: Construct the basic catalog number based on the number of units per system and the power available. Add dash numbers for the temperature class and options. Style A includes the PCU. Above ground mounting hardware is included except 2 inch EMT for the legs. Order baseplates, transformer bases, and all other below ground items separately. Example: 880A2A-2 is an FAA L-880 system. It includes the PCU and tilt switches for voltage operation. 880A2B-2-11 is an ICAO PAPI system. It includes the EMT legs and it does not have tilt switches.
