TECHNOLOGY February/March 2018 airportbusiness 37 to highlight a single circuit helps save time and effort when troubleshooting an issue with a circuit. Knowing the exact path a circuit takes through an expansive airfield significantly speeds up the repair process. Following the mapping phase of the project is a cleanup project where abandoned and dead wires will be removed in an effort to clean up the worst manholes, using a re-numbering scheme for all the circuits on the airfield. By having an accu- rate 3D map, the project can be more efficient in choosing which manholes to clean up and where the majority of the dead and abandoned wires are in the duct banks. INTELLIGENT WAY TO SAVE TIME AND MONEY Three-dimensional mapping for airfield lighting systems is an intelligent solution capable of provid- ing cost and time savings to airport management. With a detailed 3D map of the electrical wires across an entire airport on hand, maintenance and airport personnel can have a true picture of what is going on the with airfield lighting system, which is beneficial for both immediate repairs and future improvements. Since the 3D map is built upon the 2D map, it offers smart functionality for personnel with the ability to hover over a numbered manhole on the map to see the exact circuits in the duct and cor- responding duct number. By utilizing this technol- ogy, airports achieve a number of benefits: 1. Maintenance can quickly view which wires in a duct or manhole are dead, abandoned or live. This makes the repair process simpler and safer. 2. Reduction in the number of flight delays. By making maintenance efficient, taxiways and runways don't need to be shut down for long. 3. Improved time/cost savings for future air- field improvement projects. By having an accurate as-built paired with a detailed 3D map of the entire airfield lighting system, improvement projects can be more detailed and accurate in scope. By not having to hunt down as-built drawings from the past 20-30 years, users can pull up the model and find out exactly what circuits and duct banks are entering and exiting the project lim- its. The 3D map gives the airport a more realistic and accurate model of all the wires in the airfield electrical system. CHALLENGES TO OVERCOME While 3D mapping has proven useful for model- ing airfield lighting systems, especially at ATL, the technology still presents some drawbacks. For one, and as is the case when adopting any new technology, to most effectively utilize an emerging platform, training must be in place to ensure proper adoption and use. As sched- ules are often crowded as is, making the time for additional training can prove challenging. And as the technology is still in its infancy and only available on desktop computers, the lack of remote, in the field training is still unavailable. With the influx of data available with 3D map- ping technology, files sizes are significantly larger than their 2D mapped counterparts. This results in a slower experience for those unaccustomed to the new technology. However, 3D mapping is still inherently tied to the older technology as a 3D map cannot be created without first surveying and creating a 2D map first. This also poses a chal- lenge as the two files are not automatically synced together. Meaning, if a team member updates the 2D file, the 3D file is not updated automatically and must be manually recreated. This requires effective communication among team members to ensure all project files are accurate and up-to-date. 3D MAPPING IN THE FUTURE While there are challenges with any new tech- nology, the use of 3D mapping for airfield light- ing systems is on the brink and will continue to gain traction in the future. The benefits for airports now, and especially as the technology advances, are unmatched. With detailed and accurate 3D representation of the airfield electrical lighting system, airport managers can be save time and money across all facets of business. From maintenance and repair time reduction to time and cost savings for future airport improvement projects to a reduction in flight delays, airports that smartly adopt technology can remain leaders. As the 3D mapping technology evolves throughout the engineering industry, it is important for those in the airfield lighting field to remain abreast of the updates and on the leading edge of technology usage. By staying on the cutting edge of technology, airfield lighting engineers can provide unique solu- tions to satisfy their client's needs.
