Product Introduction

Runway visual range is the main basis for determining the minimum takeoff standard, the minimum approach standard, the classification standard of precision approach and landing operation, the minimum standard of airport operation, and the minimum planning standard. The runway visual range directly determines whether the runway can be opened normally and the feasible approach mode of aircraft.

Transmissive runway visual range measuring equipment uses laser with the most sensitive wavelength recognized for human eyes as the transmission light source. Based on the standard algorithm of ICAO, by measuring the transmission attenuation of the laser in the atmosphere, combined with the airport runway light intensity and the brightness of the atmospheric background light, it accurately calculates the maximum distance from the airport runway pavement signs, runway boundary lights or center line lights that the pilot in the aircraft cockpit can see on the runway. The equipment includes: laser transmitting terminal, optical receiving terminal and remote control terminal. The system can fully automatically measure the airport runway visual range and airport visibility.

Product advantages

• This product uses the laser with a wavelength of 532nm, which is the most sensitive to human eyes, as the light source, avoiding measurement errors caused by other wavelengths. The direct measurement results of this wavelength ensure the objective reflection of atmospheric visibility and runway visual range.

• This product is equipped with automatic identification function for extreme weather (heavy haze, sandstorm, rain and snow, etc.) and realtime temperature compensation system, which ensures that the system can provide stable measurement data under changing seasons, sudden changes in temperature characteristics and other environmental conditions

• The contrast sensitivity thresholds for the human eyes and illumination thresholds in this product can be either recommended by ICAO or adjusted according to the visual parameters of the observer, controller or pilot, which can ensure that the measurement results of the system are comparable to manual observation.

• Self-alignment technology is used for the transmitting terminal and receiving terminal of this product, the micron dimension ultra-high precision fully automatic auxiliary alignment system always ensures the measurement accuracy of extinction coefficient and effectively overcomes the alignment difficulties of the transmitting terminal and receiving terminal.

• This product adopts patented window pollution compensation technology, which can monitor window pollution in real time and dynamically compensate according to the detection results, effectively reducing the maintenance frequency of personnel and promptly reminding personnel to clean the window.

• The full Chinese interface of this product dynamically reports the runway visual range.
