The Airstair tester is designed to support the Weber airstair aboard any Boeing product.
Designed to interface with the installed airstair the tester allows the troubleshooting of these complex systems to be made very simple. Using a graphical airstair control/interface, the technician can operate and adjust the airstairs from inside the e-bay, using the tester to determine each sequence of operation as well as the correct sequences and switch adjustments at his fingertips!!! This shall make the airstairs operator freindly.
