Through driver authentication, location tracking and geo-fencing, wireless GSE fleet management systems provide a last layer of security for parked aircraft against potential terrorist attacks. Vehicle access control (driver authentication) prevents unauthorized personnel from using an airside vehicle — such as a fuel truck — as a weapon. Location tracking and remote vehicle deactivation can be employed to stop suspicious vehicle behavior. And geo-fencing (electronic boundaries of authorized and unauthorized geographic regions within the airport) can trigger automatic security alerts and vehicle shut-down based on defined emergency conditions.
As a safety system, wireless management of GSE has much to offer. Vehicle access control (driver authentication) ensures only fully accredited operators can use the GSE for which they are trained (a mandate of many government health and safety organizations). Vehicle inspection checklists are also often a regulatory requirement, and wireless systems provide the most fool-proof, cost-effective way to administer and enforce such requirements. With these tools — plus impact and speed sensing — wireless GSE management systems establish total operator accountability, which typically results in fewer GSE accidents, fewer injuries to ground handling personnel, and less damage to aircraft. In addition, the geo-fencing and remote shut-down capabilities of a wireless system can prevent GSE runway incursions.
Perhaps the greatest benefit of wireless GSE fleet management technology is the impact it can make on productivity — specifically, the ability to help ground handlers respond quickly, with the right resources, to meet the constantly changing demands of flight schedules. With real-time graphical visibility of vehicle location, finding borrowed or misplaced equipment is quick and easy, eliminating the significant time that is typically wasted searching for such equipment. Two-way text messaging and automated dispatch capabilities also provide GSE managers with a new way to allocate resources “on the fly” and direct work efforts to optimize aircraft turnaround. In addition, wireless GSE fleet management systems enable time-motion studies and peak asset utilization analyses that identify and quantify opportunities for fleet optimization and “right-sizing.”
Choosing the Right Wireless Technology
IT and ground support managers may debate over which wireless technology to deploy to best support the business needs of GSE management. Each technology has positives and negatives, so it is crucial to understand how different wireless systems handle different operational scenarios — especially how they respond to adverse conditions, such as interference from other wireless systems at the airport, saturation of airwaves during emergencies, wireless network outages, and “blind spots” where real-time wireless connectivity may not be available.
The most popular wireless choices are:
- “Closed-loop” long-range RFID-based systems, especially application-specific technology designed for vehicle tracking
- GPRS (General Packet Radio Service) mobile data systems that use third-party cellular networks
- “Wi-Fi” (802.11) systems that work over an existing Wireless local Area Network (WLAN)
Closed-loop RFID technology has many significant advantages, as illustrated in the table below.
