ZA737 - PAPI Light - ATG Airports - Description - The Precision Approach Path Indicator (PAPI) unit provides two colour (red and white) approach path information from a wingbar arrangement.

The ZA737 is a three lamp unit; the ZA757 is a two lamp unit. Both have identical 2’ to 3’ of arc transition performance but the three lamp units allow for one lamp out per unit but still leaving a fully operational wingbar. The units can be converted to CHAPI by inserting CHAPI filter gate.
