PAPIlandingfor airport

Product Description
The Precision Approach Path Indicator (PAPI) is designed for civil airports and heliports to provide pilots with a clear visual glide-path reference for safe approach and landing. The unit integrates electronic angle monitoring, onboard logging and robust environmental protection for reliable field operation.

Specification

• Automatic shutdown when the elevation angle exceeds the preset threshold; each lamp includes an individual electronic angle chip with real-time LED digital readout (accuracy up to 0.01° / 0.6 points) and onboard angle data storage.
• Separate "operation" and "flight-calibration" modes to simplify commissioning and in-field adjustments.
• Individual lamp runtime tracking with system status logging and exportable records.
• Integrated calibration bubble to verify optical angle after flight calibration.
• Control electronics thermally isolated from heat sources to reduce risk of heat-related failures.
• Self-positioning optical design for lamps and color filters, eliminating the need for re‑calibration when replacing optical components.
• Lightweight aluminum-alloy housing with specialized surface treatment; all fasteners in corrosion-resistant stainless steel.
• Compact footprint with aerodynamic design offering wind resistance up to 161 km/h.
