Airsafe LED PAPI: Outstanding performance to grant the safest pilot guidance on the approach operations, with the most sophisticated LED technology, achieving the following features:
-
- Best optical design in the market: Based on the camera principle the Airsafe LED PAPI unit provides a really narrow transition area (pink area) fewer than 1,2 minutes of arc, while FAA requires 3 and 5 minutes of arc for the centre and edge of the beam, respectively.
-
-
- Three sets of angle management systems ensure that PAPI angle can be retrieved in any case.
-
- Integrated digital clinometer with 4 modes of operation:
-
-
- C – Calibration.
- A – Normal operation.
- F – Storage mode.
- E – Error when abnormal system conditions.
-
- The chromaticity of the red and white area is pure, especially red, reaching CIE x+y>0.999 while ICAO requires 0,980 and FAA requires 0,998.
-
- Intelligent electrical control system can automatically turn off the light in case of abnormal conditions.
-
- Anti-condensation design inside and outside the PAPI unit grants the optical performance will be accurate under any weather conditions:
-
-
- Internal cooling to condensate and evacuate water vapor when the ambient humidity is high.
- Lens heater to dissipate condensation of the lens when the ambient temperature is too low.
