Introduction

GB/T 7256 "Civil Airport Navigation Aids Lamps" is planned to consist of five parts.

---Part 1. General requirements. It mainly stipulates that tungsten lamps and LEDs are used as light sources in civil airports, and the power supply voltage does not exceed General requirements for 1000V navigation aid lamps. Suitable for providing light guidance signals for aircraft taxiing, takeoff or approach and landing.

Navigation lights. The main products covered are approach lights, runway threshold identification lights, runway threshold wing bar lights, runway threshold lights, and runway end lights.

Lights, touchdown zone lights, runway center line lights, runway edge lights, taxiway center line lights, taxiway edge lights, stop lights, runway warning lights, etc.

---Part 2. Sequential flashing lights and runway threshold identification lights. Mainly stipulates those used in civil airports to provide aircraft with clear Requirements for runway approach directional guidance sequence flashing lights and runway threshold identification lights.

---Part 3. Precision approach course indicator. It mainly stipulates the purpose of use in civil airports to provide pilots preparing to land with Requirements for precision approach path indicators depending on precision approach path indication. The main products covered are precision approach course indicators (PAPI) and Simplified Precision Approach Path Indicator (APAPI).

---Part 4. Wind Vane. Mainly stipulates the requirements for wind vanes used in civil airports.

---Part 5. Aviation beacons. Mainly stipulates the equipment used in civil airports to indicate the location of the airport to aircraft (aircraft). requirements for aviation beacons. The main products covered include medium-intensity airport beacons, medium-intensity seaplane base beacons, high-intensity beacons Airport beacons, high-intensity seaplane base beacons, low-intensity airport beacons, low-intensity seaplane base beacons, etc. Civil airport navigation aids Part 3. Precision approach course indicators

1 Scope
