2 FIXTURE DESCRIPTION
2.1 General characteristics
The PAPI fixtures are designed for the purpose of providing visual guidance to aircrafts in the bichromatic approach
flash signalling:
●
Four-light PAPI: the system (in use in commercial and military airports) consists of 4 units each equipped
with 2 or 3 lamps (200 W), current-powered in environments with temperatures between -55 °C [-67 F] and
+55 °C [+131 F].
●
Two-light PAPI: the system (in use in commercial airports or heliports) consists of 2 units each equipped
with 2 lamps (100 or 200 W), current-powered in environments with temperatures between -55 °C [-67 F]
and +55 °C [+131 F].
The halogen lamps installed allow to minimize maintenance costs. Optics, made up of an aluminium parabolic
reflector, a filter and a lens assure uniform intensity and the red/white rapid transition to provide the pilot with an
accurate reporting on the glideslope approaching the runway. The PAPI fixture is a device able to offer in the same
optics visible and infrared operating states.
