  NEW LED PAPI Proudly manufactured by Research Engineers

Development of PAPI
The Precision Approach Path Indicator, commonly known as PAPI, was devised by Tony Smith and David Johnson at the Royal Aircraft Establishment Bedford in 1974, and developed by them over the ensuing two years. Research Engineers (RE) were also pioneers in the development of PAPI, having produced and supplied PAPI units for the first trials conducted. Today Research Engineers are pioneeers once again, in developing the LED PAPI.
