Mobile Light Measurement of Airfield Lighting System

Commissioning of New Installations and Preventive Maintenance
Annex 14, Volume I, recommends regular measurements of light intensity of Airfield Lighting Installations, at least twice a year with a Civil Aviation Certified device.Since October 2003, airports have to submit compliancy report of their installations against the ICAO standards. (Amendment n°5 to Annex 14)This officialises the requirement for a Preventive Maintenance System for Airfield Lighting that meets the safety regulations. It has to be regularly monitored to ensure that it meets ICAO standards.

Optimising maintenance works and stocks
PAC is a mobile system for evaluating all inset and elevated lights. The test report provides the candela value of each light, and identifies any defect requiring action to be taken. It also makes it possible to monitor lamp ageing from previous runs so that all the results for a runway or taxiway can be compared.
This enables the airfield lighting department to plan its operations and manage its stocks as efficiently as possible. If the lamp is not defective although the system indicates a low intensity, the identification facility guides the search and thus optimises maintenance operations >back to top

Operation of the PAC system
The system is installed on the front of a standard vehicle. Measurements are made in real time as the vehicle travels over the lights at a speed up to60km/h.
The luminous intensity detected is fed to a data processing program which stores and processes several thousand values for each light.This technique provides the average intensity of the main beam in candelas, its maximum intensity, as well as the colour and elevation settings of the lights.PAC can be used to evaluate any light source shining on its surface giving an illumination of more than 10 lux. >back to top

Alignment Control
In order to ensure the best alignment, the driver looks at a video monitor fed by a camera fitted on PAC strip.
Certification and calibration
Each unit manufactured by FB Technology is calibrated and certified on the basis of a specification drawn up by the S.T.N.A. >back to top
