Boeing said six airlines adopted its in-flight monitoring system in the first half of the year, bringing to 15 the number of airlines and freight carriers to sign for the program. Airlines, including Japan Airlines, Singapore Airlines, Air Austral, Austrian Airlines, Emirates, TNT Airways and Virgin Atlantic, have adopted the Airplane Health Management (AHM) system, which provides real-time monitoring and decision support for 42 percent of the world’s 777s and 28 percent of its 747-400s. "With this tool, airlines can address problems proactively and begin working on issues before an airplane lands and arrives at the gate. That kind of lead time can help an airline turn what might have been a costly, disruptive delay into routine maintenance," said Dan da Silva, vice president of Sales and Marketing for Boeing Commercial Aviation Services.
