Precision Approach Path Indicator – PAPI

These units can be used to create the PAPI or APAPI systems used on Heliports or Airports.

The purpose is to signal the pilots if they are on the correct landing angle. Depending on the approach angle combination of white and red lights will be seen. More reds mean the angle is too low, more white means it is too high.

  • Housing powder-coated aluminum, RAL 1004 (aviation yellow)
  • Anti-glare visor powder-coated aluminum, RAL 1004 (gloss black)
  • Diffuser hardened front glass for sandblasting protection
  • Cable gland nickel-plated brass
  • Fastening system powder-coated aluminum, RAL 1004 (aviation yellow)

In the unit, it is integrated an electronic clinometer.

The calibration is made in the factory so the user has just to install the PAPI on the desired angle then push the user calibration button. From this position, if the reading is changed with half-degree the light will automatically be turned OFF and one relay will have an open circuit to signal the failure.

Electrical Characteristics

Precision Approach Path Indicator can be made in more powering input voltages

  • 230 VAC
  • 24 V DC
  • 48 VDC
  • 2.8…6.6 A from a CCR

The total power is around 50 W per unit.

If needed we can make these units powered by solar systems.

Optical Characteristics

We use RED and white OSRAM LEDs for these units and specially designed optics for the best optical output.
